AIS subcontracted the California Native Plant Society (CNPS) to conduct field reconnaissance assistance for this project, as well as accuracy assessment (AA) field data collection; and Soar Environmental Consulting to assist in the AA field data collection. CDFW's Vegetation Classification and Mapping Program (VegCAMP) provided in kind service to allocate and score the AA. The mapping study area, consists of approximately 1,824,939 acres, of Mariposa, Madera, Tulare, Kern, and Los Angeles counties. Work was performed on the project between 2019 and 2022. The primary purpose of the project was to further CDFW's goal of developing fine scale digital vegetation maps as part of the California Biodiversity Initiative Roadmap of 2018. CNPS under separate contract and in collaboration with CDFW VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The vegetation map was produced applying heads-up digitizing techniques using a 2018 base of one-meter National Agricultural Imagery Program (NAIP) imagery (truecolor and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 2 acres; exceptions are made for wetlands and riparian types, which were mapped to a 1-acre MMU. Field reconnaissance and accuracy assessment enhanced map quality. There was a total of 111 mapping classes. The overall Fuzzy Accuracy Assessment rating for the final vegetation map, at the Alliance and Group levels, is 89.5 percent.211115:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=211115Thu, 12 Mar 2026 11:12:34 -07002022-03-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc.

This report provides a summary of the accuracy assessment allocation, field sampling methods, and accuracy results; it also provides a change comparison between the new 2022 map and the existing 2012 vegetation map where 32,000 acres or ~37% of the mapped area was burned within those past 10 years. California state standards (CDFW 2024) require that a fine-scale vegetation map should achieve an overall accuracy of 80%; after final scoring, the 2022 Orange County vegetation map received an overall accuracy of 84.6%. Within the recent fire footprints, we found an overall decrease in acres of coastal sage scrub and a corresponding increase in post-fire seral scrub types. Some sensitive natural communities such as Tecate cypress (Hesperocyparis forbesii Association) increased in acreage over the past 10 years in unburned areas. Other communities such as Cactus scrub (Opuntia littoralis Alliance) had a 17% decline in acreage due to recent fires, likely negatively impacting populations of the coastal cactus wren. This fine-scale vegetation re-map provides valuable insight into the ecological response of vegetation over time to inform long-term land management and conservation within the remaining natural lands of Orange County.242409:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=242409Tue, 24 Feb 2026 13:15:31 -08002025-01-01T00:00:00Suisun Marsh Vegetation Map - This report summarizes the methods and results of the 2024 Suisun Marsh triennial vegetation map update. This update by the North State Planning and Development Collective at California State University, Chico, is part of an ongoing triennial vegetation monitoring program for the Suisun Marsh. The project tracks changes in the Suisun Marsh vegetation over time to fulfill specific requirements of the Suisun Marsh Plan of Protection of 1984, the Suisun Marsh Preservation Agreement of 1986, the 2015 Suisun Marsh Preservation Agreement, and associated regulatory permits. This is the eighth update using the current mapping standards originally implemented in 1999. All of the previous vegetation maps from 1999 to 2021 can be viewed and downloaded using the online California Department of Fish and Wildlife (CDFW) Biogeographic Information and Observation System (BIOS); the links to the associated reports are included in the map metadata. For detailed information regarding the history and evolution of this project, see Appendix A in the 2012 update report (Boul and Keeler-Wolf 2016). The final map covers 91,486 acres, containing vegetation and land use polygons ranging from 0.001 acres to 418 acres and averaging 1.8 acres. The tidally influenced acreage is covered by 13,106 vegetation polygons; 36,392 vegetation polygons cover the leveed acreage. 232836:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=232836Tue, 24 Feb 2026 11:30:49 -08002025-01-01T00:00:00Vegetation Mapping Report - Mapping standards and the map classification for the vegetation map of the 199,000 acre Potential Tehachapi Pass High Speed Rail Corridor area are presented.

This area is a biologically diverse mix of habitats including annual and perennial grasslands, oak woodlands, riparian scrub and forests, and foothill chaparral types. The vegetation map is based upon 1-m resolution digital color aerial imagery. It includes 67 map units, of which 54 are natural vegetation map units at the floristic alliance level or higher (group) level and 13 are non-vegetation land use mapping units. The resulting vegetation map and supporting surveys provide baseline data with great floristic and ecological detail. Information from this project is being used to assess conservation and management objectives in the region, and it will enable wildlife, wildfire, and climate change modeling in the future. 31346:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=31346Tue, 24 Feb 2026 11:16:34 -08002011-02-01T00:00:00Vegetation classification and mapping standards - Vegetation Protocols for Sampling, Mapping, and Accuracy Assessment for the Doyle-Loyalton mapping area, including field forms and protocols, data entry protocols, quality control protocols, and mapping standards and attributes. 151006:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=151006Tue, 24 Feb 2026 10:58:43 -08002020-11-01T00:00:00Vegetation classification, description and key - This report describes 118 alliances and 212 associations that are found in Sonoma County, California.

The mapping was done in a two-part effort. The first phase started in 2016 and covered the ecoregion subsections named Cottonwood-Skedaddle Mountains, Likely Mountain, and the eastern portion of Eagle Lake-Observation Peak (Miles and Goudey 1997) which covered nearly 1.1 million acres. A summary of the mapping units, frequency (number of polygons mapped) and acres for Phase 1 can be found in Table 6. The second phase began in 2018 and covered the ecoregion subsections named Devil's Garden and Adin Mountains, which covered an additional 866,228 acres. A summary of the mapping units, frequency (number of polygons mapped) and acres for Phase 2 can be found in Table 7. The vegetation map followed guidelines set forth by the National Vegetation Classification System and A Manual of California Vegetation. It is an Alliance level map overall, with photo-interpreters attempting to map to the more specific Association level when they were confident to go to that level of detail. The Association level map from the first phase was incorporated into a bird species occupancy study by CDFW to see if birds choose to reside in specific vegetation communities.

A crucial step of vegetation management is the production of a vegetation map. We mapped the Whiskeytown Unit of the Whiskeytown-Shasta-Trinity National Recreation Area. Vegetation was classified and mapped to the Association-Alliance level, the Alliance level and, for some classes, to the mixed alliance level to facilitate cross walk to fuel types. Recent advances in satellite imaging capabilities (1-meter spatial resolution) and pattern recognition software that considers neighborhoods of picture elements facilitated the compilation of this electronic map and database. The previously developed, vegetation classification at Whiskeytown National Recreation Area served as the basis for making the vegetation map. We modified this classification to reflect actual conditions in the study area. We produced three versions of the vegetation map of the Whiskeytown Unit. The Association-Alliance map offers maximum classification detail with 38 classes (31 plant associations, 5 alliances, 1 Disturbed class and a Barren class). Because we sometimes experienced confusion by the contextual classifier when defining associations, we aggregated to the alliance level (20 alliances, Disturbed, and Barren classes) and finally to an appropriately mixed alliance level of classes that we defined as "Mapping Units" (13 alliances, 3 mixed alliances called Mapping Units, and a combined Barren - disturbed class). Results of mapping at the vegetation association-alliance level indicated that two abundant classes covered 24 percent of the landscape: the Canyon live oak/whiteleaf manzanita association and the Mixed conifer alliance in near equal proportion. Six classes covered between 5 and 9 percent each for a total of 44 percent of the land area. The remaining thirty classes were rarer, covering 32 percent of the land area. In the alliance level map, four alliances (Canyon live oak forest, Ghost pine woodland, Mixed conifer forest, Ponderosa pine forest) covered between 11 and 17 percent of the landscape each for a total of 56 percent of the land area. Another four alliances covered between 5 and 9 percent of the landscape for a total of 30 percent. The remaining 14 least abundant alliances covered 14 percent of the land area. In the Mapping Unit level map, four Mapping Units (Canyon live oak forest, Ponderosa pine forest, Mixed conifer forest, Mixed pine - mixed oak) covered between 11 and 24 percent of the land area each for a total of 64 percent of the landscape. The remaining ten, less abundant Mapping Units covered 14 percent of the land area. 16313:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=16313Fri, 21 Nov 2025 09:37:09 -08002006-02-15T00:00:00standardsVegetation classification and mapping standards - The Survey of California Vegetation (SCV) defines the process of vegetation classification and mapping as a series of integrated steps.

AIS subcontracted the California Native Plant Society (CNPS) to conduct classification development work needed for this project, as well as accuracy assessment (AA) field data collection. The California Department of Fish and Wildlife's (CDFW) Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate and score the AA. The mapping study area, consisting of approximately 66,402 acres, of Lassen County. Work was performed on the project between 2019 and 2021. The primary purpose was an effort toward BLM's goal of developing fine-scale digital vegetation maps for all the public lands it manages in California. The vegetation classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on new surveys and classification work conducted in collaboration with CDFW VegCAMP. The map was produced applying heads-up digitizing techniques using a base of one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 1 acre; exceptions are made for wetlands and riparian types, which were mapped to a 1/4 acre MMU. Field reconnaissance and accuracy assessment enhanced map quality. There was a total of 78 mapping classes. The overall Fuzzy Accuracy Assessment ratings for the final vegetation map at the Alliance level were 86.3 percent at the 60-100% Correct or Acceptable level, and 81.9 percent at the 80-100% Correct or Acceptable level.

The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification is the basis for an integrated vegetation map of the same area expected to be completed in 2021 by CSU Chico's Geographical Information Center (GIC). Ecologists with the California Department of Fish and Wildlife's (CDFW) Vegetation Classification and Mapping Program (VegCAMP) and the California Native Plant Society (CNPS) analyzed species data from 857 field surveys collected in the study area between 2016 and 2020. The data include 627 surveys collected from 2016 to 2019 with funding provided by CDFW Region 1 specifically for this classification effort. An additional 230 surveys collected immediately adjacent to the study area by CNPS through funding from the Bureau of Land Management (BLM) are included in the analysis, providing a broader, regional understanding. Nearly 1200 samples from the US Forest Service, recent Assessment Inventory and Monitoring (AIM) BLM-NRCS field samples, surveys from the US National Parks Service for Lava beds National Monument, and VegCAMP surveys from past vegetation projects that were collected within the Modoc Plateau and NW Ecoregions (USDA) were also included in the analysis. A total of 8 tree-overstory, 25 shrub, and 28 herbaceous alliances are described, with 14 tree-overstory, 41 shrub, and 29 herbaceous associations. Included within this report is a project introduction, methods, and results. It includes a floristic key to all vegetation types, descriptions and stand tables for all alliances and associations included in the study area, a table showing the full local classification nested within the USNVC hierarchy, and a crosswalk showing the relationship between this and other classification systems. The descriptions summarize distributional, structural, environmental, and plant species data for each type.183030:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=183030Sun, 02 Nov 2025 08:55:33 -08002021-02-01T00:00:00Vegetation Mapping Report - The Nature Conservancy (TNC) contracted Aerial Information Systems, Inc (AIS) to develop a vegetation map covering approximately 23,800 acres (~37 square miles) of the Garcia River Watershed east of Point Arena. The mapping area is split by the north coast and outer north coast range floristic provinces as defined by The Jepson Manual - Higher Plants of California, Hickman. The goal of the project was to create a baseline vegetation map depicting existing conditions within the study area at the time the base imagery was flown in 2005. The vegetation map will be used by TNC to track changes that may occur to vegetation and associated wildlife habitats over time, to better understand the distribution of oaks and related tanoak which may in the future be susceptible to sudden oak death and to contribute to building a better statewide vegetation map on lands where TNC has conservation interest.41130:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=41130Fri, 24 Oct 2025 14:21:09 -07002007-11-01T00:00:00Vegetation Map Accuracy Assessment Report - Cow Creek and Mill Creeks are east-side tributaries to the north Sacramento River that provide important habitat for native fish and other wildlife. To-date however, both watersheds have lacked detailed and spatially explicit information on the existing vegetation and ecological condition of the riparian corridors. To address this information gap and to help guide future restoration and enhancement efforts, this project was initiated with three primary goals: (1) map the riparian and adjacent vegetation; (2) assess conditions of the riparian corridors; and (3) develop recommendations in the form of an annotated list, on priority action areas for restoring or enhancing riparian vegetation. This project is funded through the Anadromous Fish Restoration Program administered by the US Fish and Wildlife Service. To map vegetation along the river corridors for Mill and Cow Creeks, we used a combination of remotely collected and field collected data. For three weeks in 2013, a field crew surveyed vegetation types at 244 points and performed more in-depth surveys of riparian conditions at 81 points in both watersheds. These field data provided ground truthing information for the draft vegetation map and information on riparian conditions. A draft vegetation map of the riparian corridors was created using aerial imagery from a variety of sources. Two attributes associated with riparian vegetation that are new or unusual components of vegetation maps were included in this effort: vegetation overhang along the stream channel and meadow type based on a hydrogeomorphic classification for the Sierra Nevada, published in 2011. Ground truthing demonstrated that the draft vegetation map had an overall accuracy of 89%. As a first step in the riparian conditions assessment, the riparian corridor within both watersheds was divided into reaches with consistent geology, hydrology and surrounding land use. Within these areas, information from the mapping effort, field surveys, technical documents and other spatially explicit data were used to assess riparian conditions. We used eight structural characteristics discernable using remote imagery or GIS data layers as indicators of riparian condition and then applied a consistent scoring scheme to develop advisory condition quantifications for each condition reach. These were used with other site-specific and less easily quantified information to develop final condition scores for each condition reach. Reaches with lower condition scores were more closely examined using remote imagery and other information sources to identify, in an annotated list, high priority areas for restoration and enhancement in Cow Creek and Mill Creek watersheds.101389:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=101389Fri, 24 Oct 2025 12:39:24 -07002015-04-01T00:00:00Vegetation Mapping Report - The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation map of Slinkard Valley and Little Antelope Valley Wildlife Areas in Mono County, California. The vegetation classification was derived from data collected in the field during the periods August 28-31, 2017, September 10-14, 2018, and November 5-9, 2018. Vegetation polygons were drawn using heads-up "manual" digitizing using the 2016 National Agricultural Imagery Program (NAIP) true color and color infrared (CIR) 1-meter resolution data as the base imagery. Supplemental imagery included NAIP true color and CIR 1-meter resolution data from 2009-2012, BING imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is 1 acre, with the exception of wetland and riparian types, which have an MMU of ½ acre. Mapping is to the National Vegetation Classification System (NVCS) hierarchy association, alliance, or group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. 165535:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=165535Fri, 24 Oct 2025 12:17:28 -07002021-08-01T00:00:00Vegetation Classification Report - This report consists of a vegetation classification system for the Central and Coastal Subregions of Orange County.

AIS subcontracted the California Native Plant Society (CNPS) to conduct classification development work needed for this project, as well as accuracy assessment (AA) field data collection. The California Department of Fish and Wildlife's (CDFW) Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate and score the AA. The mapping study area, consisting of approximately 84,574 acres, of Modoc and Lassen Counties. Work was performed on the project between 2017 and 2021. The primary purpose was an effort toward BLM's goal of developing fine-scale digital vegetation maps for all the public lands it manages in California. The vegetation classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on new surveys and classification work conducted in collaboration with CDFW VegCAMP. The map was produced applying heads-up digitizing techniques using a base of one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 1 acre; exceptions are made for wetlands and riparian types, which were mapped to a 1/4 acre MMU. Field reconnaissance and accuracy assessment enhanced map quality. There were a total of 91 classes mapped. The overall Fuzzy Accuracy Assessment ratings for the final vegetation map at the Alliance level were 92.2 percent at the 60-100% Correct or Acceptable level, and 86.4 percent at the 80-100% Correct or Acceptable level. At the Association level, the Fuzzy Accuracy Assessment ratings were 88.1 percent at the 60- 100% Correct or Acceptable level, and 79.1 percent at the 80-100% Correct or Acceptable level. 191774:8https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=191774Thu, 23 Oct 2025 14:30:53 -07002021-03-01T00:00:00Vegetation Map Accuracy Assessment Report - A set of contingency tables showing each accuracy assessment survey and what vegetation type was in the map vs. what the vegetation keyed to on the ground.192229:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=192229Thu, 23 Oct 2025 13:54:34 -07002021-05-01T00:00:00Vegetation Mapping Report - The California Native Plant Society (CNPS) received a private donation to conduct field sampling, produce a vegetation classification, and fine-scale, spatially and floristically accurate vegetation map in the southern Sierra Nevada Foothills (SSNF). A pilot mapping area in this region was chosen based on input from the Sierra Foothills Conservancy, and encompasses approximately 35,000 acres (including about 2,300 acres of reservoir) around Eastman and Hensley Lakes in Madera County. This area was immediately adjacent to the Northern Sierra Nevada Foothills vegetation map produced by Aerial Information Systems in an effort led by the California Department of Fish and Game and completed in 2011. The mapping area included mostly private lands except for the areas adjacent to Eastman and Hensley Lakes, which are owned by the Army Corps of Engineers. Some of the privately owned properties have easements with the Sierra Foothills Conservancy. The classification of vegetation types used in the map was based on a previous vegetation classification of 47 native vegetation alliances and semi-natural stands from surveys collected between 2008 and 2010 across a larger region of about 300,000 acres (Roach et al. 2011). Guidelines for assessing and mapping the plant communities are found in the widely accepted California standards for interpreting vegetation patterns and for initiating local and regional ecological assessments (see A Manual of California Vegetation, Sawyer et al. 2009).101387:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=101387Thu, 23 Oct 2025 12:56:15 -07002014-10-10T00:00:00Vegetation Classification Report - This is a classification report placeholder.

Additionally, three other associations were also described: Pinus muricata - Chrysolepis chrysophylla / Arctostaphylos nummularia in the Pinus muricata - Pinus radiata Alliance; Arctostaphylos nummularia in the Arctostaphylos (nummularia, sensitiva) Alliance; and Chrysolepis chrysophylla / Vaccinium ovatum in the Chrysolepis chrysophylla Alliance. Two provisional associations in the Sequoia sempervirens Alliance need additional sampling: Sequoia sempervirens - Pinus muricata and Sequoia sempervirens - Hesperocyparis pygmaea. Mapping the vegetation and land cover types on the extent of the oligotrophic soils in what is likely the historical extent of the Mendocino Cypress (Hesperocyparis pygmaea) Woodland and related vegetation reveals a loss of between 20% and 44% of these sensitive vegetation types due to agricultural and urban development.161736:12https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=161736Wed, 22 Oct 2025 15:05:09 -07002019-01-01T00:00:00Appendix C - This is an excel appendix for the Classification and Mapping of Mendocino Cypress (Hesperocyparis pygmaea) Woodland and Related Vegetation on Oligotrophic Soils, Mendocino and Sonoma Counties, California.238124:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=238124Wed, 22 Oct 2025 15:01:50 -07002019-01-01T00:00:00Vegetation Mapping and Accuracy Assessment - This is a mapping report for the remap of the CVFPPA section of the Central Valley and change detection done between this map based on 2016 NAIP imagery with a past mapping done using 2009 NAIP Imagery. The Central Valley Riparian Mapping developed by the Geographic Information Center (GIC) is used as a planning tool for the Department of Water Resources (DWR) and stakeholders in planning regional flood management projects and plans associated with the Central Valley Flood Protection Plan (CVFPP). These data are used to assess current areas of vegetation and habitat within the flood protection system, set measurable objectives within CVFPP Conservation Planning areas for the enhancement of specific types of habitat, and create initial assessments of potential impacts of proposed multi-benefit projects associated with the State Plan of Flood Control. This dataset was developed as part of the California Department of Water Resource's Central Valley Flood Protection Program to facilitate regional planning and conservation and enhancement of biological resources by the Department of Water Resources, project partners, and regional stakeholders.184992:8https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=184992Tue, 21 Oct 2025 17:11:34 -07002021-12-01T00:00:00Vegetation Mapping Report - The California Department of Fish and Game and GreenInfo Network have created a vegetation map of the Ballona Wetlands Ecological Reserve, Los Angeles County, California, under a grant from the California Coastal Conservancy to assist in restoration planning. Vegetation mapping classes are based on existing National Vegetation Classification standards to the extent possible. Mapping was based on a 1-foot pixel resolution (±1:16,800) true color orthophoto taken June 13, 2006 by I.K. Curtis Aerial Photography under contract to the Coastal Conservancy, and on field work conducted in 2007.16316:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=16316Tue, 21 Oct 2025 17:10:55 -07002007-01-01T00:00:00Vegetation classification, description and key - This report describes approximately 110 alliances and 280 associations that occur in Marin County, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification forms the basis for an integrated, countywide vegetation map supported through a collaboration by Golden Gate National Parks Conservancy, National Park Service, Tukman Geospatial LLC, and other partners of the Marin Countywide Vegetation Map and Landscape Database Project. Vegetation ecologists from the California Native Plant Society analyzed species data from 6,407 field surveys collected between 1992 and 2019. The data included 255 new surveys collected in 2018 and 2019 through funding provided specifically for this classification effort. Additional surveys were compiled for the analysis from previous sampling efforts in Marin (2,966) and from adjacent counties (3,186) to provide a broader, regional understanding. A total of 26 tree-overstory, 29 shrubland, 53 herbaceous and 2 sparsely vegetated alliances are described, with 79 tree-overstory, 72 shrubland, 127 herbaceous and 3 sparsely vegetated associations. The report results include summary tables of county-wide classification results including a count of surveys by alliance. Appendices include a floristic key of vegetation types, a table of vegetation types nested within the USNVC hierarchy, and descriptions of each vegetation alliance and association. The descriptions contain stand tables which summarize structural and species cover data for each type; stand tables serve as a reference for the countywide expression of vegetation, as well as plant palettes for future restoration efforts. The appendix with vegetation descriptions can be found here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=195295195293:7https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=195293Tue, 21 Oct 2025 17:10:16 -07002021-09-01T00:00:00Vegetation Mapping - CNPS has initiated a project with partners at the Bureau of Land Management (BLM) and The Nature Conservancy (TNC) Phase 1 of the project includes detailed vegetation mapping in the northwestern portion of the Ciervo Panoche Natural Area (CPNA).

The mapped area is bounded to the west and south by USDA Ecoregional Subsection 322Ag of the Mojave Desert (Miles and Goudey 1997). To the east, the portion mapped by AIS (approx. 4,202,000 acres) is bounded by the borders of a vegetation map produced in 2004 for the Mojave Desert Ecosystem Program (MDEP). VegCAMP mapped a portion of the area mapped previously for the MDEP (approx. 776,000 acres) using the finer-scale rules and classification that AIS used for the larger portion (see Figure 1). The boundary of VegCAMP's study area was chosen to eliminate an arbitrary hole in AIS's work area based on the MDEP boundary around Ord Mountain, absorb an additional core area for the Mojave Ground Squirrel, include more critical habitat area for the Desert Tortoise, and ensure access to 1-ft. ancillary imagery via ImageConnect©. 47996:8https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=47996Tue, 21 Oct 2025 17:07:23 -07002012-06-01T00:00:00Vegetation Mapping Report - The U.S. Geological Survey (USGS) and the National Park Service (NPS) Vegetation Characterization Program initiated a project at Joshua Tree National Park (JOTR or Park) in 1996 to classify, describe, and map the vegetation communities of the Park. The project, including the final map, classification, and report, was completed in 2012. Initial mapping, photo-interpretation, and field work was conducted between 1996 and 2005. Final reports for these efforts were generated by 2005, including a map, ecological descriptions, classification, key, and photo-interpretation guide. Following this, a total of 1,313 accuracy assessments were conducted in 2007 and 2008, the results of which spurred additional field relevés and a reworking of the map and classification. An additional 111 relevés were conducted in 2009 targeting problematic associations and alliances; these data were used in conducting additional analyses to produce a revised vegetation map and classification. Photo-interpretation was also redone during this time for a subset of the problematic associations and the classification was updated to match the most recent vegetation classification presented in the Manual of California Vegetation Second Edition (Sawyer et al. 2009). Between 2010 and 2011 data analysis was completed and incorporated into the final map and classification. By February 2012 the ecological descriptions were updated and completed to match (as best as possible) the most recent version of the U.S. National Vegetation Classification and the map was updated to reflect the final nomenclature.85348:8https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=85348Tue, 21 Oct 2025 17:06:57 -07002013-04-01T00:00:00Vegetation Mapping Report - This document summarizes the methods and results for vegetation change detection in Suisun Marsh conducted by the Wildlife and Habitat Data Analysis Branch of the California Department of Fish and Game. This effort is the continuation of a habitat monitoring and assessment program undertaken in 1999 and reported in Vegetation Mapping of Suisun Marsh, Solano County: A Report to the California Department of Water Resources (Keeler-Wolf et al. 2000). The change detection process uses the existing 1999 digital vegetation map and classification, 2003 aerial photograph interpretation, database functions, and geographic information systems (GIS) editing and processing. Field data was collected to strengthen the existing classification and improve map accuracy. The study area is bounded by the 10-foot elevation contour surrounding Suisun Marsh on the west, north and east, and extends into the open water beyond the tidal flats and marsh vegetation in Suisun Bay to the south; the Potrero Hills are excluded. In total, 69,316 acres were assessed for vegetation change. Within this area 98 rapid assessment plots were collected over the summer of 2003 and 31,218 vegetation polygons were examined against aerial photography. Over the 4-year study period, 16.8% of the study area was interpreted to have changed.18254:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18254Tue, 21 Oct 2025 17:05:47 -07002004-09-01T00:00:00Vegetation Mapping Report - Aerial Information Systems (AIS) and the California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) with assistance from the California Native Plant Society (CNPS) created a fine-scale vegetation map of portions of the Mojave and Colorado Deserts in California. Approximately six million acres spanning desert portions of Inyo, Kern, Los Angeles, San Bernardino, Riverside, and Imperial Counties were mapped between 2011 and 2012. The primary purpose was to develop an accurate vegetation map for the California desert as it pertains to renewable energy sources and conservation opportunities, helping planners identify high quality habitat and rare communities. The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of true-color and color infrared 2010 one-meter National Agricultural Imagery Program (NAIP) imagery in conjunction with ancillary data and imagery sources. Map polygons were assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a one or five acre MMU) and areas characterized as Land Use polygons (which were mapped to a 2.5 acre MMU). Field reconnaissance and accuracy assessment enhanced map quality. A total of 46,803 map polygons representing 137 vegetation map classes were developed. The overall accuracy assessment rating for the final vegetation map was 84.59 percent.62826:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=62826Tue, 21 Oct 2025 17:05:07 -07002013-04-01T00:00:00Vegetation Classifcation and Mapping Report - Aerial Information Systems (AIS) with assistance from the California Department of Fish and Wildlife (CDFW), the Vegetation Classification and Mapping Program (VegCAMP), and the California Native Plant Society (CNPS) created a fine-scale vegetation map of portions of the Mojave and Sonoran Deserts in California. Approximately 2,195,415 acres spanning desert portions of Inyo, San Bernardino, Riverside, and Imperial Counties were mapped between 2014 and 2016. The primary purpose was to develop an accurate vegetation map for the California desert as it pertains to renewable energy sources and conservation opportunities, helping planners identify high quality habitat and rare communities. The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of 2014 true-color and color infrared one-meter National Agricultural Imagery Program (NAIP) imagery in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a 1 or 5 acre MMU, depending on type) and areas characterized as Land Use polygons (which were mapped to a 2.5 acre MMU). Field reconnaissance and accuracy assessment enhanced map quality. A total of 88 vegetation classes were mapped. The overall accuracy assessment rating for the final vegetation map was 91.90 percent. 131751:7https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=131751Tue, 21 Oct 2025 17:04:19 -07002016-05-01T00:00:00Vegetation - The initial land cover map used for the DRECP was a composite dataset created primarily from California Gap (2008 CA-GAP) Vegetation (USGS GAP Program, Lennartz et al. 2008) with updates for agricultural and urban areas from California Farmland Mapping and Monitoring Program (FMMP) (California Department of Conservation 2009). Once the land cover map was adapted to the NVCS system, new vegetation mapping conducted in the West Mojave, Lucerne Valley, and East Riverside areas using the NVCS was incorporated into the land cover map using the common classification system. . Additionally, datasets from the Mojave Desert Ecosystem Project, Joshua Tree National Park, and Anza-Borrego Desert State Park were incorporated. 64051:7https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=64051Tue, 21 Oct 2025 17:03:55 -07002013-03-27T00:00:00Vegetation Map Accuracy Assessment Report and Overview - Aerial Information Systems (AIS) and the California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) created a vegetation map of a 5,969,650-acre portion of the Mojave Desert and Colorado Desert in California to assist with the development of the Desert Renewable Energy Conservation Plan (DRECP). The map was produced using heads up digitizing based on 2010 National Agricultural Imagery Program (NAIP) imagery. The minimum mapping unit (MMU) was 10 acres, with exceptions made for wetlands and certain wash types (1 acre MMU) and areas characterized as human land use polygons (2.5 acre MMU). This map will provide planners with detailed information to help identify high quality habitats and rare communities. Although the primary purpose of the map is to document vegetation communities, it provides multiple attributes including structural data such as herbaceous, shrub and tree cover, and information about the level of disturbance within the vegetation stand. These are important habitat factors for Covered Species of the DRECP, including the Mohave ground squirrel and desert tortoise. This report covers the project purpose, intended map uses, and accuracy assessment of the map as conducted by VegCAMP and the California Native Plant Society. A separate report by AIS (Menke et al. 2013) discusses the ecological setting in the mapping area and provides a thorough discussion of mapping standards and methods. Their report also includes descriptions, photointerpretation signatures, distributions, elevation ranges, and ground photos of the vegetation types mapped.62825:7https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=62825Tue, 21 Oct 2025 17:03:15 -07002013-03-27T00:00:00Vegetation Mapping Report - The University of California Riverside's Center for Conservation Biology (CCB) has created fine-scale vegetation maps for a number of Conservation Areas under the jurisdiction of the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) under contract with the Coachella Valley Conservation Commission (CVCC). The primary purpose for creating these maps is provide a landscape-scale approach to monitoring changes due to land use, invasive species, recreation, hydrology, and climate. These digital maps, documenting changes and their causes, are then tools for prioritizing future conservation actions. The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS; Federal Geographic Data Committee 2008). The classification is meant to align with previous and concurrent efforts previous survey and classification work done by California Department of Fish and Wildlife's Vegetation Classification and Mapping Program (VegCaMP) and Aerial Information Systems (AIS) for the Desert Renewable Energy Conservation Plan Area as well as the southeastern Salton Sea Mid-Desert Area, and by the National Park Service for Joshua Tree National Park. This unit was mapped using the California Department of Fish and Wildlife (CDFW) and California Natural Plant Society Combined (CNPS) Vegetation Classification and Mapping Program protocol (CNPS 2014). The primary purpose was to develop a dynamic and accurate vegetation map for the Coachella Valley Floor Reserve Management Unit (Figure 1), so that it may be applied to further conservation efforts and assist with management of the 27 species and 27 natural communities listed within the plan. Map polygons were assessed for vegetation type, percent cover, presence of exotics, anthropogenic disturbance, and roadedness. This map and report describes a map correction for the year 2013 as well as an updated map for the year 2018 for the area within the 95,000 acres that fall within the 18 CVMSHCP Management Units on the Coachella "Valley Floor." Within the study areas, rapid assessment protocol vegetation plots, basic vegetation assessment plots and supplemental reconnaissance observations were obtained within the study at pre-determined points in order to document the plant community, disturbances, and invasive species across space and types. Heads-up photo- interpretation of 2013 local flight true-color imagery, fine-scale National Agriculture Imagery Project (NAIP) imagery (USDA, 2012, 2014, 2016 and 2018) and field information were combined to produce delineations of vegetation alliances and associations according to the California Department of Fish and Wildlife classification system, outlined in the Manual of California Vegetation (MCV) Second Edition (Sawyer et al. 2009). 174970:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174970Tue, 21 Oct 2025 17:02:42 -07002019-09-30T00:00:00Natural Communities - This is the transcript of a video (https://www.youtube.com/watch?v=KvBTf67xFvc) that provides an overview of Sensitive Natural Communities with examples from the Modoc Plateau region in northeastern California, based on a recently-completed fine-scale vegetation mapping project.189052:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=189052Tue, 21 Oct 2025 17:02:09 -07002020-10-02T00:00:00Vegetation Mapping - The primary objective of this project is to provide a preliminary vegetation classification and detailed vegetation map for the mainstem Santa Clara River riparian corridor and its major tributaries within Ventura and Los Angeles Counties, from Bouquet Canyon to the estuary. The 116-mile-long Santa Clara River flows in a westerly direction from headwaters on the northern slopes of the San Gabriel Mountains in Los Angeles County, through the Santa Clara River Valley and the Oxnard Plain in Ventura County, and empties into the Pacific Ocean near the City of Ventura (Figure 1). The Santa Clara River riparian corridor, however, has retained a significant amount of high-quality riparian habitat that supports a diversity of native wildlife, including threatened and endangered species such as least Bell's vireo (Vireo bellii pusillus), southwestern willow flycatcher (Empidonax traillii extimus), and yellowbilled cuckoo (Coccyzus americanus). The present-day Santa Clara River is a dynamic semi-arid ecological system driven primarily by periodic short duration, high intensity flood events (Stillwater Sciences 2005). 220145:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=220145Tue, 21 Oct 2025 17:01:11 -07002019-01-01T00:00:00Vegetation Classification Report - The Vegetation Program of the California Native Plant Society (CNPS) has developed a floristic classification of alliances and associations within the Great Valley Ecoregion Section of the USDA Ecological Subregions of California (Miles and Goudey 1997). This study area encompasses a wide range of plant communities from vernal pool grasslands and alkali flats to densely wooded riparian corridors. The resulting vegetation classification is supported by both new and compiled data from this region including 808 surveys collected across 2010-2011 by staff of Chico State University's Geographical Information Center (GIC) and the California Department of Fish and Game (CDFG). The CNPS-CDFG Combined Vegetation Rapid Assessment and Relevé protocol was implemented for these new field surveys. An additional 1807 field surveys, collected across 2001-2011, have been collated and merged with the new data, and a total of 2615 surveys have been used to develop a floristic classification analysis. The vegetation classification has been produced using the National Vegetation Classification System's hierarchy of alliances and associations. The plant communities are floristically and environmentally defined, following the format of A Manual of California Vegetation (Sawyer et al. 2009). In this report, vegetation types are summarized within a key and descriptions that differentiate 138 alliances and 242 finer-level associations. Of the vegetation alliances currently identified within the Great Valley Ecoregion, 6 are newly described types (with at least 10 samples) and 13 are new provisional types (with fewer than 10 samples). The floristic vegetation classification was translated into a mapping classification to produce a fine-scale map of the natural vegetation features in this region. The resulting map can serve as a baseline for future climate-change monitoring, environmental assessment, fire/fuels modeling, rare and invasive species management, and a host of other valuable analyses. 64011:10https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=64011Tue, 21 Oct 2025 17:00:30 -07002012-04-01T00:00:00Vegetation and GIS - This is a transcript of a video (https://www.youtube.com/watch?v=AYQoqSTgzaM) which shows examples of how Survey of California vegetation maps are used, and details on the limitations of these maps including minimum mapping units, crosswalks, and accuracy189054:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=189054Tue, 21 Oct 2025 16:59:51 -07002020-10-02T00:00:00Vegetation and Ecological Site Descriptions - This is a transcript for a video (https://www.youtube.com/watch?v=4BXsr8d1q3o) showing examples of how Survey of California vegetation maps can be used to improve NRCS data development for Ecological Sites, State and Transition Models, and Rangeland Health.189058:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=189058Tue, 21 Oct 2025 16:59:24 -07002020-10-02T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc. (AIS) was contracted by the Coachella Valley Conservation Commission (CVCC) through a Local Assistance Grant originating from the California Department of Fish & Wildlife (CDFW) to map and describe the essential habitats for bighorn sheep monitoring within the San Jacinto-Santa Rosa Mountains Conservation Area. This effort was completed in support of the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP). The completed vegetation map is consistent with the California Department of Fish & Wildlife classification methodology and mapping standards. The mapping area covers 187,465 acres of existing and potential habitat on the northern slopes of the San Jacinto and Santa Rosa Mountains ranging from near sea level to over 6000 feet in elevation. The map was prepared over a baseline digital image created in 2014 by the US Department of Agriculture - Farm Service Agency's National Agricultural Imagery Program (NAIP). Vegetation units were mapped using the National Vegetation Classification System (NVCS) to the Alliance (and in several incidences to the Association) level (See Appendix A for more detail) as described in the second edition of the Manual of California Vegetation Second Edition (Sawyer et al, 2009). The mapping effort was supported by extensive ground-based field gathering methods using CNPS rapid assessment protocol in the adjacent areas as part of the Desert Renewable Energy Conservation Plan (DRECP) to the north and east; and by the 2012 Riverside County Multiple Species Habitat Conservation Plan vegetation map in the western portion of Riverside County adjacent to the west. These ground-based data have been classified and described for the abovementioned adjacent regions and resultant keys and descriptions for those efforts have been used in part for this project. The Peninsular Bighorn Sheep Habitat (PBSH) Vegetation Map will help inform scientists in their effort to study fluctuations in the distribution of Peninsular bighorn sheep due to changes in vegetation due to fire, drought and climate change. Thus, the primary goals and objectives of the vegetation map are to develop a spatial geodatabase of vegetation communities deemed essential for Peninsular bighorn sheep habitat and to provide a baseline to monitor natural communities and landscape-scale vegetation change within their range. Quantification of biotic habitat variables will help assess factors that influence Peninsular bighorn sheep and other species population fluctuations. These data are key to conservation of biological diversity in the Plan area, especially given the impacts of increasing periods of drought and effects of climate change. In addition, the completed map is necessary in order to address changes in vegetation makeup due to increased fire frequency and extent throughout the mapping area. 138663:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=138663Tue, 21 Oct 2025 16:56:19 -07002016-11-01T00:00:00Vegetation - This is a transcript of a video (https://www.youtube.com/watch?v=KvBTf67xFvc) which provides an overview of the methods and products that for the fine-scale vegetation classification and map of the Modoc Plateau and surrounding region189049:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=189049Tue, 21 Oct 2025 16:55:48 -07002020-10-02T00:00:00Vegetation Mapping Summary - This fine scale grassland map represents native grasslands and low-cover shrublands throughout select East Bay Regional Parks District (EBRPD) lands - a 74-class grassland map with 2,805 polygons.

It is intended for use in image interpretation-based identification of vegetation. The key follows the hierarchy of the current United States National Vegetation Classification (USNVC) as of the publication of the Manual of California Vegetation (Sawyer et al., 2009). The USNVC hierarchy is promoted by the Federal Geographic Data Committee (FGDC) and the Ecological Society of America's Vegetation Panel (FGDC 2008, Faber-Langendoen et al. 2014).219808:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=219808Mon, 20 Oct 2025 15:33:22 -07002023-03-13T00:00:00Vegetation Mapping Report - This report documents the methods and results of the fine-scale, countywide vegetation map of Santa Cruz and Santa Clara Counties. The map represents the state of the landscape in summer, 2020, when the high-resolution imagery for the two counties was collected. In 2020 the Santa Cruz Mountains Stewardship Network (SCMSN or the Network), initiated a fine scale vegetation mapping project in Santa Cruz and Santa Clara counties. The Network is a region-wide and cross-sector collaboration of independent individuals and organizations who are committed to practicing effective stewardship on their own lands and coordinating their efforts with other land stewards to enhance stewardship on a regional level. The Network facilitated multiple meetings with potential project stakeholders and, with support from the San Mateo Resource Conservation District, was able to build a consortium of funders to map all of Santa Cruz and Santa Clara counties. The consortium included Big Creek Lumber, CALFIRE - Santa Clara Unit, CALFIRE - Santa Cruz/San Mateo Unit, California Department of Fish and Wildlife, California Department of Parks and Recreation, California State Coastal Conservancy, County of Santa Cruz, County of Santa Clara Technology Services and Solutions, Gordon and Betty Moore Foundation, Midpeninsula Regional Open Space District, National Oceanic and Atmospheric Administration - Coastal Change Analysis Program (C-CAP), Peninsula Open Space Trust, Resources Legacy Fund, San Francisco Public Utilities Commission, Santa Clara Valley Open Space Authority, Santa Clara Valley Water District, Save the Redwoods League, UC Santa Cruz Natural Reserves, and United States Geological Survey, 3D Elevation Program. Over a 3-year period, the project, collectively referred to as the "Santa Cruz and Santa Clara Fine Scale Veg Map", produced numerous environmental GIS products including impervious surfaces, wildland fuels, orthophotography, and other land cover maps. A 121-class fine-scale vegetation map was completed in June 2023 that details vegetation communities and agricultural land cover types, including forests, grasslands, riparian vegetation, wetlands, and croplands.219717:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=219717Mon, 20 Oct 2025 15:31:51 -07002023-06-19T00:00:00Vegetation Classification - Stand tables and descriptions of all the alliances and associations that were part of the Santa Clara/Santa Cruz vegetation classification219807:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=219807Mon, 20 Oct 2025 15:31:12 -07002023-01-01T00:00:00Vegetation Classification Report - This report describes approximately 130 alliances and 330 associations that occur in Santa Clara and Santa Cruz Counties, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification forms the basis for an integrated, countywide vegetation map supported through a collaboration by Santa Cruz Mountains Stewardship Network, Tukman Geospatial LLC, and other partners of the Countywide Vegetation Map and Landscape Database Project, Santa Clara & Santa Cruz. Vegetation ecologists from the California Native Plant Society analyzed plant species data from over 8,600 field surveys collected between 1992 and 2022. The data included over 1,200 new surveys collected in 2020 and 2021 in association with this classification effort. Additional surveys were compiled for the analysis from previous sampling efforts in Santa Clara and Santa Cruz Counties (847), and from nearby counties (more than 6,600) to provide a broad, regional understanding. A total of 32 tree-overstory, 41 shrubland, and 60 herbaceous alliances are described, with 119 tree-overstory, 89 shrubland, and 126 herbaceous associations.219719:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=219719Mon, 20 Oct 2025 15:30:22 -07002023-01-01T00:00:00Vegetation Classification - Ciervo-Panoche, Hubbard Hill, vegetation descriptions220226:9https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=220226Mon, 20 Oct 2025 15:29:15 -07002023-01-01T00:00:00Vegetation sampling, classification, and mapping report - With funding from the Bureau of Land Management (BLM), the California Native Plant Society (CNPS) Vegetation Program has collected and compiled vegetation data, produced a vegetation classification, and produced a fine-scale vegetation map of select BLM land units in the inner Central Coast of California. During this effort, CNPS completed vegetation sampling across the southern portion of the Ciervo-Panoche Natural Area (CPNA), including 21 relevé plots and 52 rapid assessment surveys, that represent 28 vegetation alliances. Building upon previous vegetation sampling and mapping efforts, we also compiled and quality-controlled >1,800 surveys of vegetation data from BLM to develop a robust regional vegetation classification of the inner Central Coast. All new and compiled classification data are stored within a geodatabase and a standardized Access database. CNPS additionally produced a fine-scale vegetation map for ~7,300 acres across three BLM allotments in San Luis Obispo County: Hubbard Hill, Anderson Canyon, and Freeborn Mt (HUBB). We have employed heads-up digitizing techniques based upon 2020 National Agricultural Imagery Program (NAIP) aerial imagery for San Luis Obispo County. The minimum mapping unit (MMU) is 1 acre, and the map units follow the National Vegetation Classification Standard and State of California Vegetation and Mapping Standards. The map includes 15 vegetation map units, with additional attributes including structural information (e.g., herbaceous, shrub and tree cover), as well as disturbance and site quality information for each polygon. Field reconnaissance and verification enhanced the final map quality. This report provides a summary of the methods and results of field sampling, data compilation, classification, and mapping. The project deliverables include a geodatabase consisting of fine-scale vegetation map polygons and field survey data, a floristic key and descriptions of inner Central Coast vegetation types which provide baseline information for long-term land management, conservation, and wildlife protection.220225:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=220225Mon, 20 Oct 2025 15:28:15 -07002023-01-01T00:00:00Vegetation Mapping and Accuracy Assessment - Sonoran Deserts in California. Approximately 555,000 acres, spanning desert portions of Kern, San Diego, and Imperial Counties were mapped between 2017 and 2020 within the Desert Renewable Energy Conservation Plan (DRECP) area. The primary purpose was to develop an accurate vegetation map for portions of the California desert as it pertains to renewable energy sources and conservation opportunities, helping planners identify high quality habitat and rare communities. The vegetation classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). California Native Plant Society (CNPS), as a subcontractor to AIS, conducted any classification development work needed for this project. The classification is based on new and previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of 2016 one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a 1 or 5 acre MMU depending on type), and areas characterized as Land Use polygons (which were mapped to a 2.5 acre MMU). In the transition to non-desert areas the MMU transitioned to 1 acre for upland types and 1/4 acre for special types. Field reconnaissance and accuracy assessment enhanced map quality. A total of 88 vegetation classes were mapped. The overall accuracy assessment ratings for the final vegetation map were 87.7 percent for User's Accuracy, and 88.6 for Producer's Accuracy.191778:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=191778Mon, 20 Oct 2025 15:27:17 -07002021-03-01T00:00:00Vegetation Mapping Report - The California Native Plant Society (CNPS) received a private donation to produce a fine-scale, spatially and floristically accurate vegetation map with field sampling in the southern Sierra Nevada Foothills. This included a focus mapping area of approximately 11,640 acres near Millerton Lake. The area is mainly in the Millerton Lake East quadrangle and includes 2,990 acres of the McKenzie Preserve at Table Mountain and 754 acres of Big Table Mountain. These protected areas contain vernal pools on basalt lava-flow table mountains, which provide habitat for rare plants and crustaceans. Vegetation surveys from 2008 to 2010 resulted in a classification of 47 native vegetation alliances and semi-natural stands across a larger region of around 300,000 acres, and this contextual information was applied to a detailed vegetation map across the focused mapping area. The mapped lands are managed by the Bureau of Land Management, Bureau of Reclamation, Department of Fish and Game (DFG), and Department of Parks and Recreation for Millerton State Recreation Area, as well as private land owners and the Sierra Foothills Conservancy. Guidelines for assessing and mapping the plant communities are found in the widely accepted California standards for interpreting vegetation patterns and for initiating local and regional ecological assessments (see A Manual of California Vegetation, Sawyer et al. 2009). 87983:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=87983Mon, 20 Oct 2025 15:26:42 -07002011-01-01T00:00:00Vegetation Classification Report - This report describes approximately 90 alliances and 200 associations that occur in San Mateo County, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification forms the basis for an integrated, countywide vegetation map supported through a collaboration by Golden Gate National Parks Conservancy, National Park Service, Tukman Geospatial LLC, and other partners of the San Mateo Countywide Vegetation Map and Landscape Database Project. Vegetation ecologists from the California Native Plant Society analyzed species data from 6,425 field surveys collected between 1992 and 2019. The data included 394 new surveys collected in 2019 through funding provided specifically for this classification effort. Additional surveys were compiled for the analysis from previous sampling efforts in San Mateo (746), San Francisco (6), and from nearby counties (5,279) to provide a broader, regional understanding. A total of 27 tree-overstory, 24 shrubland, and 37 herbaceous alliances are described, with 64 tree-overstory, 54 shrubland, and 78 herbaceous associations.212666:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=212666Mon, 20 Oct 2025 15:26:23 -07002021-01-01T00:00:00Vegetation Mapping and Accuracy Assessment - In 2018, the Golden Gate National Parks Conservancy (Parks Conservancy) (https://parksconservancy.org), non-profit support partner to the National Park Service (NPS) Golden Gate National Recreation Area (GGNRA), initiated a fine scale vegetation mapping project in Marin County. The GGNRA includes lands in San Francisco and San Mateo counties, and NPS expressed interest in pursuing fine scale vegetation mapping for those lands as well. The Parks Conservancy facilitated multiple meetings with potential project stakeholders and was able to build a consortium of funders to map all of San Mateo County (and NPS lands in San Francisco). The consortium included the San Francisco Public Utilities Commission (SFPUC), Midpeninsula Regional Open Space District (MROSD), Peninsula Open Space Trust (POST), San Mateo City/County Association of Governments, and various County of San Mateo departments including Parks, Agricultural Weights and Measures, Public Works/Flood Control District, Office of Sustainability, and Planning and Building. Over a 3 year period, the project, collectively referred to as the "San Mateo Fine Scale Veg Map", has produced numerous environmental GIS products including 1 foot contours, orthophotography, and other land cover maps. A 106-class fine-scale vegetation map was completed in April 2022 that details vegetation communities and agricultural land cover types, including forests, grasslands, riparian vegetation, wetlands, and croplands. The environmental data products from the San Mateo Fine Scale Veg Map are foundational and can be used by organizations and government departments for a wide range of purposes, including planning, conservation, and to track changes over time to San Mateo County's habitats and natural resources.212663:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=212663Mon, 20 Oct 2025 15:26:10 -07002022-10-21T00:00:00Vegetation Mapping Report - This report summarizes the methods and results of the 2015 Suisun Marsh triennial vegetation map update. This update is part of an ongoing monitoring project conducted by the Vegetation Classification and Mapping Program (VegCAMP) of the California Department of Fish and Wildlife (CDFW), in collaboration with the Department of Water Resources (DWR) and the CDFW Bay Delta Region. The project tracks changes in the Suisun Marsh vegetation over time to fulfill specific permit requirements of the Suisun Marsh Plan of Protection of 1984 and the Suisun Marsh Preservation Agreement of 1986. This is the sixth update using the current mapping standards originally implemented in 1999. An Accuracy Assessment was conducted on the 2015 map based on 260 field samples collected in the summer of 2016. After consulting with the Environmental Coordination Advisory Team (ECAT), we have reduced the number of map classes. Reassigning map classes per the revised map classification improved producers' accuracy to 85.9% and users' accuracy to 84.3%. 149178:12https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=149178Mon, 20 Oct 2025 15:25:53 -07002018-05-01T00:00:00Natural Communities - As new areas of the state come under study, and as regional classification efforts combine and analyze surveys from multiple projects, community concepts and community names change. Some changes to the California communities happen to keep in sync with changes at the National (NVC) level. Changes also can happen because of plant nomenclature. The following sections show changes that have happened to the Alliance and Association levels of California's Natural Communities.161686:12https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=161686Mon, 20 Oct 2025 15:25:08 -07002025-02-01T00:00:00Vegetation Mapping and Accuracy Assessment - This report documents the methods and results of the fine-scale, countywide vegetation map of Marin County, CA. The map represents the state of the landscape in summer, 2018, when the high-resolution imagery for the county was collected. Development of the Marin fine-scale vegetation map was managed by the Golden Gate National Parks Conservancy and staffed by personnel from Tukman Geospatial (https://tukmangeospatial.com/) Aerial Information Systems (AIS; http://www.aisgis.com/), and Kass Green and Associates. The fine-scale vegetation map effort included field surveys by a team of trained botanists. Data from these surveys, combined with older surveys from previous efforts, were analyzed by the California Native Plant Society (CNPS) Vegetation Program (https://www.cnps.org/vegetation) with support from the California Department of Fish and Wildlife Vegetation Classification and Mapping Program (VegCAMP; https://wildlife.ca.gov/Data/VegCAMP) to develop a Marin County-specific vegetation classification. High density lidar data was obtained countywide in the early winter of 2019 to support the project. The lidar point cloud, and many of its derivatives, were used extensively during the process of developing the fine-scale vegetation and habitat map. The lidar data was used in conjunction with optical data. Optical data used throughout the project included 6-inch resolution airborne 4-band imagery collected in the summer of 2018, as well as 6-inch imagery from 2014 and various dates of National Agriculture Imagery Program (NAIP) imagery. In 2019, Tukman Geospatial staff and partnersconducted countywide reconnaissance fieldwork to support fine-scale mapping. Field-collected data were used to train automated machine learning algorithms, which produced a fully automated countywide fine-scale vegetation and habitat map. Throughout 2020, AIS manually edited the fine-scale maps, and Tukman Geospatial and AIS went to the field for validation trips to inform and improve the manual editing process. In the spring of 2021, draft maps were distributed and reviewed by Marin County's community of land managers and by the funders of the project. Input from these groups was used to further refine the map. The countywide fine-scale vegetation map and related data products were made public in June 2021. In total, 107 vegetation classes were mapped with a minimum mapping size of one fifth to one acre, varying by class. Accuracy assessment plot data were collected in 2019, 2020, and 2021. Accuracy assessment results were compiled and analyzed in the summer of 2021. Overall accuracy of the lifeform map is 95%. Overall accuracy of the fine-scale vegetation map is 77%, with an overall 'fuzzy' accuracy of 81%. 213079:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=213079Mon, 20 Oct 2025 15:24:45 -07002022-03-22T00:00:00Vegetation Classification and Mapping - The National Park Service Vegetation Mapping Inventory Program funded an effort, beginning in 2010, to classify and map the vegetation at Lava Beds National Monument. Southern Oregon University and Klamath Network staff performed the inventory work. The Klamath Network coordinated the effort. To classify the vegetation, we sampled 169 representative vegetation classification plots throughout the 18,936 hectare (46,792 acre) project area using traditional phytosociological methods (i.e., relevé sampling). The relevé plots were located and sampled primarily in 2010 and 2011. We identified a total of 222 vascular plant species in the relevé plots, including several species that were not previously recorded on the monument's species list. These were added to the flora of the monument by Sean B. Smith published in 2014. We classified the plot data into 24 plant associations using standard vegetation analysis methods. We provide a key to the plant associations and descriptions of each association in Appendices B and D of this report. Mapping of the vegetation polygons was completed via manual digitizing of vegetation types visible on the most recent National Agriculture Imagery Program (NAIP) and ESRI World imagery. A number of plant associations could not be consistently distinguished in the imagery. Based on our analysis, what could be distinguished accurately on the imagery, and a minimum mapping unit of 0.5 ha, we defined 15 vegetation mapping classes that were related to vegetation associations. Up to two of these vegetation classes were mapped as present in each polygon, and the percent cover that each one occupied in a polygon was coded in the database. The percent cover attribute for the primary and secondary (if present) vegetation in each polygon was estimated from photographic and field evidence. In addition, the occurrence of up to two associations and their percent cover were identified as composing the primary and secondary vegetation. We conducted map accuracy assessment in 2013 by visiting 505 stratified random accuracy assessment plots throughout the project area. The field data were compared to the vegetation map to determine accuracy. Our initial map had an overall thematic accuracy that was slightly below the 80% standard set by the National Program. To improve accuracy, we merged two vegetation types resulting in an overall thematic accuracy of 85% for the primary vegetation. Accuracy was difficult to assess for some rare types. We also assessed the accuracy of the primary association in each polygon, which was 82%. 235741:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=235741Mon, 20 Oct 2025 15:24:31 -07002025-12-01T00:00:00Vegetation Classification Key - This is the vegetation key for Sierra Nevada Foothills Ecoregion (USDA). It is based on 3,661 vegetation samples; 1,847 surveys collected between 2003 and 2006 in the northern Sierra Nevada Foothills and 1,703 surveys collected between 2008 and 2016 in the southern Sierra Nevada Foothills. Data from other projects that intersected with the Sierra Nevada Foothills (the Foothills) were included adding 117 surveys. This key follows the hierarchy from the Manual of California Vegetation (MCV) at the time of classification. This key is not dichotomous but instead may present more than two options for each key break. Users should read all options in each key break carefully and sequentially to arrive at the correct vegetation type. This vegetation key includes all expected vegetation types including those that are not accurately detectable in remotely sensed imagery. Alliance and association names are frequently followed by a number, e.g. (n=5). An asterisk (*) following an alliance name indicates there were no samples classified to that type, but it is expected to occur in the region based on remotely sensed imagery, species distributions and/or personal communications. In some cases, the number of samples recorded for an alliance will equal the sum of the samples recorded for the associations below it. If this is not the case, then some samples could not be classified below the alliance level.216890:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=216890Mon, 20 Oct 2025 15:23:39 -07002023-11-01T00:00:00Mapping Report Central California Foothills Coastal Mountains - The purpose of this project was to contribute to state-wide vegetation classification and to create a comprehensive digital map of vegetation communities within the California State Parks using vegetation survey data. Creation of this map has multiple purposes, including but not limited to the following: assisting land managers in decision-making, fire and fuel management, protecting endangered species and habitats, protecting cultural and natural resources, outlining habitat connectivity, guiding habitat restoration, guiding conservation prioritization, and informing development. The map produced for this project is part of a greater collaborative effort to create a comprehensive vegetation map for all of California. This project involved the collection of 403 Rapid Assessment and Relevé vegetation surveys. The completed map covers a surface area of 88,003.92 acres and has a total of 11,027 polygons with 94 vegetation mapping units.233466:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=233466Mon, 20 Oct 2025 15:05:11 -07002024-01-01T00:00:00Vegetation Classification Alameda Countra Costa - This report includes approximately 120 alliances and 280 associations that occur in Alameda and Contra Costa Counties, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification forms the basis for an integrated, two-county vegetation map supported through a collaboration by California State Coastal Conservancy (SCC), East Bay Regional Park District (EBRPD), and Tukman Geospatial LLC. Vegetation ecologists from the California Native Plant Society (CNPS) analyzed vegetation data from over 2,600 field surveys collected between 1992 and 2024. The data included over 500 new surveys collected in 2022 and 2023, and 100 additional grassland surveys in 2024, in association with this classification effort. Additional surveys were compiled for the analysis from previous sampling efforts in Alameda and Contra Costa Counties (560), and from adjacent counties within the same ecoregion subsections (1,460) to provide a broad, regional understanding. A total of 29 tree-overstory, 38 shrubland, and 56 herbaceous alliances are described, with 93 tree-overstory, 66 shrubland, and 124 herbaceous associations. The report results include Alliance-level summary tables of the classification results from Alameda and Contra Costa counties, along with supporting data from surrounding counties for uncommon types. Appendices include a floristic field key of vegetation types, a table of vegetation types nested within the USNVC hierarchy, and descriptions of each vegetation alliance and association. The descriptions contain stand tables which summarize structural and plant species cover data for each type; stand tables serve as a reference for the expression of vegetation, as well as plant palettes for future restoration efforts in the region. 233251:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=233251Mon, 20 Oct 2025 15:03:42 -07002025-01-01T00:00:00Alameda Contra Costa Vegetation Map - This report documents the methods and results of the fine scale, countywide vegetation map of Alameda and Contra Costa Counties. The map represents the state of the landscape in summer, 2020, when National Aerial Imagery Program (NAIP) data was collected.233252:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=233252Mon, 20 Oct 2025 15:03:10 -07002025-01-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc. (AIS) was contracted by the Natural Communities Coalition (NCC) to create an updated fine-scale vegetation map of the regional database developed by AIS in 2012-2015. The mapping area covers approximately 86,000 acres of open space and adjacent urban and agricultural lands, including habitat located in both the Central and Coastal Subregions of Orange County. The updated map was prepared over a baseline digital image created in 2022 by the U.S. Department of Agriculture - Farm Service Agency's National Agricultural Imagery Program (NAIP). Vegetation units were mapped using the National Vegetation Classification Standard (NVCS) to the alliance level, where possible, as depicted in the online version of A Manual of California Vegetation (MCV) (CNPS 2025). One of the most important data layers used to guide the conservation planning process for the 1996 Orange County Central & Coastal Subregion Natural Community Conservation Plan/Habitat Conservation Plan (NCCP/HCP) was the regional vegetation map created in the early 1990s by Dave Bramlett and Jones & Stokes Associates, Inc. (1993). Up until 2015, this map was used to direct monitoring and management efforts in the NCCP/HCP Habitat Reserve. In 2013 AIS was contracted by the Nature Reserve of Orange County (NROC - now NCC) to create an updated regional vegetation map to 2012 conditions, completed in 2015. Refer to AIS (2015) for reporting on the 2012 update. An updated map is necessary in order to address changes in vegetation composition due to widespread and multiple burns, urban expansion, and broadly occurring vegetation succession that has occurred over the past 30 years since the original map was created, and over the last 10 years since the last update of the vegetation map was completed. The California Native Plant Society (CNPS) completed an accuracy assessment of the 2012 vegetation data and conducted a trend analysis comparison between the 1992 and 2012 vegetation maps, both of which were documented in a report produced by CNPS (Buck-Diaz & Evens 2015). For the current mapping effort, CNPS again conducted an accuracy assessment of the newly created 2022 image-based map and completed a change detection trend analysis between the 2012 vegetation map and the 2022 updated vegetation data, both of which are documented in a separate report produced by CNPS (Buck-Diaz et al., 2025). 233168:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=233168Mon, 20 Oct 2025 15:02:20 -07002025-03-01T00:00:00Vegetation Mapping Report - This report summarizes the methods and results of the 2009 Suisun Marsh vegetation map update. This is part of an ongoing monitoring project that the Biogeographic Data Branch (BDB) of the California Department of Fish and Game (CDFG), in collaboration with the Department of Water Resources (DWR) and the CDFG Bay Delta Region (BDR), started in 1999 to track changes in the Suisun Marsh vegetation over time. This is the fourth update since the original map was made in 1999. The first update, conducted in 2000, is summarized in Vegetation Mapping of Suisun Marsh, Solano County: A Report to the California Department of Water Resources (Keeler-Wolf et al. 2000). The second update, done three years later in 2003, is summarized in Suisun Marsh Vegetation Mapping Change Detection 2003 (Vaghti and Keeler-Wolf 2004). 48108:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=48108Mon, 20 Oct 2025 13:59:28 -07002012-06-01T00:00:00Vegetation Classification and Mapping Report - The California Department of Fish and Game Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation classification and map of the Pine Creek and Fitzhugh Creek Wildlife Areas, Modoc County, California following FGDC and National Vegetation Classification Standards. The map classification is based on a floristic classification that was derived from data collected in the field in June 2006 and analyzed by VegCAMP using cluster analysis to derive the classes. This classification was then translated to a mapping classification, and the map was produced using truecolor 2005 1-meter National Agricultural Imagery Program (NAIP) imagery as the base. The minimum mapping unit (MMU) is one acre, with the exception of wetland types, which were mapped down to ½ acre. Field verification of 48% of the mapped polygons was conducted in June 2007; in combination with the 2006 sampling effort, 65% of the polygons were verified in the field.24566:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24566Thu, 18 Sep 2025 11:23:12 -07002008-04-05T00:00:00Contingency Table - This table is linked in the fine-scale vegetation map of the Northern California coast.

The accuracy assessment described here was performed in the autumn of 2016. A total of 58 plots from 19 categories were evaluated. The final map accuracy was 69% using a traditional error matrix, and 89% with a fuzzy logic scoring system.175004:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=175004Wed, 16 Jul 2025 14:42:50 -07002019-10-31T00:00:00Vegetation Sampling Protocol - This protocol describes the methodology for both the relevé and rapid assessment vegetation sampling techniques as recorded in the combined relevé and rapid assessment field survey form.18599:28https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18599Tue, 20 May 2025 14:59:55 -07002024-04-16T00:00:00Vegetation Classification and Mapping Report - This report describes the work conducted at the John Muir National Historic Site in 2004. The John Muir National Historic Site (JOMU) is located in Martinez, Contra Costa County, California. Data on the vegetation of Mt. Wanda was gathered using the rapid assessment field method as developed by the California Native Plant Society (CNPS). . A formal site-specific classification using ordination was not performed and the plant communities are not fully described. Vegetation communities were delineated for the Mt. Wanda sub-unit of the John Muir National Historic Site in the summer of 2004. A total of 13 alliances and 18 associations were identified in the study area. These 13 alliances represent 7 formation types and 4 classes: forest, woodland, shrubland and herbaceous vegetation. CNPS, California Fish and Game, and NatureServe will use these data in conjunction with other agencies and vegetation mapping projects in the San Francisco Bay area to more fully develop plant community classifications specific to the area. The vegetation map resulting from this project will be used by the National Park Service (NPS) to assist with park and Network management activities and research.75295:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=75295Mon, 28 Apr 2025 08:33:42 -07002004-01-01T00:00:00Natural Communities - The list below shows changes that have been made to the rarity ranks of natural communities during the time period specified above. Changes are most often made based on data from additional projects ("Update from report") or on use of NatureServe's rarity rank calculator that assigns conservation status ranks ("Rank calculator"). Newly added communities are also provided with their ranks ("New")161688:12https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=161688Thu, 27 Feb 2025 17:49:17 -08002025-02-01T00:00:00Natural Communities - This list is a verion of the currently accepted Vegetation Alliances and Assocations (or Natural Communities List), and is based on the Manual of California Vegetation (see http://vegetation.cnps.org/). This is the California expression of the National Vegetation Classification System. The list is presented alphabetically within life forms (trees, shrubs, herbs), and includes pending changes that have been accepted but not fully developed within the MCV database. Natural Communities with ranks of S1-S3 are considered Sensitive Natural Communities to be addressed in the environmental review processes of CEQA and its equivalents. A question mark (?) denotes an inexact numeric rank because we know we have insufficient samples over the full expected range of the type, but existing information points to this rank; it is the equivalent of the ranking calculators range of rankings option. We have not provided the G and S rank of associations in the January 2018 version of this classification. However, associations currently designated as being of S3 or rarer are indicated with a Y in the Sensitive column. For alliances with State ranks of S1-S3, all associations within them are also considered Sensitive. Ranking is an ongoing process and we expect to provide association level ranks for all of the S3 or rarer entities in the future. Please note that semi-natural stands are not ranked, as these are defined and strongly dominated by non-native species. As of 2018, about half of California has been mapped and classified according to the state and national standard. Accordingly, not all Sensitive Natural Communities have been described, and the ranks of some current communities may change as we refine their known distributions.

This effort involves different methodologies from those undertaken in prior habitat monitoring and assessment of the Suisun Marsh. Therefore, it discusses them in some detail and includes recommendations based on the authors' experience with this project. The mapping project blends ground-based classification, aerial photo interpretation, and GIS editing and processing. The method is based on the development of a quantitative vegetation classification, which is used to describe the vegetation map units of the marsh. The classification is defined to meet the specifications of the National and State standards for vegetation classification, but is related through a cross-walking table to other standard classifications in use 10calIy or statewide. The reporting of this information is broken into sections on field and lab- based methods, results and conclusions. In some cases it has been necessary to describe the processes involved from the standpoint of the vegetation classifier, delineator, and mapper. Thus, there is some inherent redundancy in the report, but this we trust wilI be appreciated by the various specialists who may be interested in the product and the processes involved. The mapping area as defined in the contract is bounded by the 10-foot elevation contour surrounding the marsh on the west, north, and east and extends into the open water beyond the tidal flats and marsh vegetation in the Suisun Bay to the south. It excludes the Potrero HiIIs (see Figure 1). In total 69,323 acres were mapped. Within this area 198 vegetation samples were coIIected, 271 reconnaissance plots and 271 accuracy assessment plots were taken, and 39,460 polygons were delineated and attributed. A total of 121 mapping units were used to depict the vegetation.90000:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=90000Wed, 18 Dec 2024 08:23:48 -08002000-12-30T00:00:00Vegetation Sampling Field Form - California Native Plant Society and California Department of Fish and Wildlife combined vegetation rapid assessment and relevé field sampling form.18598:12https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18598Thu, 02 May 2024 10:44:56 -07002024-01-10T00:00:00Vegetation Classifcation and Mapping Report - A fine-scale vegetation classification and map of a portion of the Fish Slough Area of Critical Environmental Concern (ACEC) (including the California Department of Fish and Wildlife (CDFW) Fish Slough Ecological Reserve) in Inyo and Mono Counties, California, was created by the CDFW Vegetation Classification and Mapping Program (VegCAMP). The vegetation classification is derived from floristic field survey data collected during September 2011, November 2012 and June 2013 and is based on previously described Alliances and Associations, with a few new provisional types included. The map was produced using heads-up digitizing using true-color 2012 1-meter National Agricultural Imagery Program (NAIP) imagery as the base. Supplemental imagery included 2012 1-meter NAIP Color Infrared and imagery available through Bing Maps and Google Earth. The minimum mapping unit (MMU) is 1 acre for upland habitats and ¼-acre for wetland habitats. Field reconnaissance and field verification enhanced map quality. The final map includes a total of 365 polygons representing 40 vegetation map classes.76530:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=76530Mon, 29 Apr 2024 14:01:14 -07002014-01-01T00:00:00Vegetation Classification and Mapping Report - Under contract to the U.S. Bureau of Land Management (BLM), Aerial Information Systems (AIS) created a fine-scale vegetation map of portions of the Mojave Desert in California. AIS subcontracted the California Native Plant Society (CNPS) to conduct classification development work needed for this project, as well as accuracy assessment (AA) field data collection. The California Department of Fish and Wildlife's (CDFW) Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate and score the AA. The mapping study area consisted of approximately 437,073 acres in the Searles Valley and West Mojave Trails A subareas, spanning the desert portions of Inyo and San Bernardino Counties were mapped between 2019 and 2021 within the Desert Renewable Energy Conservation Plan (DRECP) area. The primary purpose was to develop an accurate vegetation map for portions of the California desert as it pertains to renewable energy sources and conservation opportunities, helping planners identify high quality habitat and rare communities. The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on new and previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of 2020 or 2018 one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a 1- or 5-acre MMU, depending on type) and areas characterized as Land Use polygons (which were mapped to a 2.5-acre MMU). In the progression to non-desert areas the MMU transitioned to 1 acre for upland types and 1/4 acre for special types. Field reconnaissance and accuracy assessment enhanced map quality. There were a total of 126 mapping classes. The overall accuracy assessment ratings for the final vegetation map was 93% overall fuzzy accuracy. 221984:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=221984Mon, 29 Apr 2024 13:46:18 -07002023-09-01T00:00:00SamplingReportVegetation sampling report - The California Native Plant Society, contracted by the California Department of Fish and Wildlife (CDFW), collected vegetation data within the Southern Sierra Nevada Foothills (SSNF), which will be used to develop a hierarchical vegetation classification and a fine-scale vegetation map of the region in future projects. Using the CNPS-CDFW Protocol for Combined Vegetation Rapid Assessment and Relevé Sampling, CNPS and partners coordinated with landowners and land managers, obtained land access permits, and collected over 700 surveys including 510 rapid assessment surveys and 202 relevé plots. We conducted field surveys across two spring seasons between April 2015 and April 2016, and these surveys represented more than 115 vegetation types. The field data was entered into the CDFW/CNPS joint SQL database and has been thoroughly quality controlled by the CNPS staff.133705:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=133705Wed, 06 Mar 2024 14:31:15 -08002016-10-31T00:00:00Vegetation Mapping Report - The 17,158 acre Johnson Valley project area is located in San Bernardino County, 32 miles east of Victorville, CA bisected by highway 247.

This effort involves new methodologies proposed to be used for many other significant natural areas in the United States. Therefore, it discusses them in some detail and includes recommendations based on the contractors experience with this project. The mapping project blends ground-based classification, aerial photo interpretation, and GIS editing and processing. The method is based on the development of a quantitative vegetation classification which is used to describe the vegetation mapping units of the park. The classification is defined to meet the specifications of the new National and State standards for vegetation classification, but is related through a cross-walking table (Table 2) to other standard classifications in use locally or state-wide. In total a 928,090 acre area was mapped. Within this area 501 vegetation samples were taken and over 23,000 polygons were delineated and attributed. A total of 94 mapping units were used to depict the vegetation.18246:12https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18246Mon, 04 Mar 2024 10:48:42 -08001998-03-01T00:00:00Riparian Vegetation - Least Bell's Vireos (LBVI) are a state and federally listed endangered species that nests exclusively in riparian areas in California. Despite being listed for ~40 years, there has never been a single map, with high thematic resolution, of riparian vegetation covering the entire breeding range of this species. Conservation Science and Data Visualization and Aerial Information Systems co-developed a standardized mapping protocol, called VireoVegMap, with the objective of providing a comprehensive map of potential LBVI nesting habitat. Dominant vegetation map units and secondary map attributes were chosen to provide specific information relevant to LBVI ecology, conservation, and management. We then applied this protocol, using 2020 aerial imagery, to create a baseline map of riparian vegetation to support vireo recovery planning and status evaluation. The overall study area consists of twenty-eight USGS Hydrologic Unit Code (HUC) 8 subbasins in Central and Southern Coastal California and Southern California Deserts. This study area is represented by a polygon feature class in the project geodatabase called "Total Study Extent". Within this large study area, a Focused Mapping Area was developed to ensure near-complete coverage of all riparian vegetation within active channels and floodplains of Level 1 stream networks (e.g., streams that terminate in the Pacific Ocean) within each HUC8 subbasin. Similar protocols were developed to cover active channels and floodplains of desert streams that flow eastward from Peninsular Ranges and terminate in playa lakes. Work was performed on the project between 2021 and 2023. Project data was produced applying heads-up digitizing techniques in an Esri ArcMap environment using 2020 National Agricultural Imagery Program (NAIP) imagery (60-centimeter base; true-color and color infrared). Ancillary imagery and data sources provided context during mapping. 215147:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=215147Fri, 15 Dec 2023 10:28:51 -08002023-08-01T00:00:00Vegetation Map Accuracy Assessment Report - Contingency table (confusion matrix) showing the accuracy assessment results for the vegetation map of the Sierra Nevada Foothills produced by Aerial Information Systems for the California Department of Fish and Wildlife216722:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=216722Fri, 27 Oct 2023 13:59:49 -07002023-10-01T00:00:00Vegetation classification, description and key - This is an appendix to a report which describes approximately 110 alliances and 280 associations that occur in Marin County, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification forms the basis for an integrated, countywide vegetation map supported through a collaboration by Golden Gate National Parks Conservancy, National Park Service, Tukman Geospatial LLC, and other partners of the Marin Countywide Vegetation Map and Landscape Database Project. Vegetation ecologists from the California Native Plant Society analyzed species data from 6,407 field surveys collected between 1992 and 2019. The data included 255 new surveys collected in 2018 and 2019 through funding provided specifically for this classification effort. Additional surveys were compiled for the analysis from previous sampling efforts in Marin (2,966) and from adjacent counties (3,186) to provide a broader, regional understanding. A total of 26 tree-overstory, 29 shrubland, 53 herbaceous and 2 sparsely vegetated alliances are described, with 79 tree-overstory, 72 shrubland, 127 herbaceous and 3 sparsely vegetated associations. The report results include summary tables of county-wide classification results including a count of surveys by alliance. Appendices include a floristic key of vegetation types, a table of vegetation types nested within the USNVC hierarchy, and descriptions of each vegetation alliance and association. The descriptions contain stand tables which summarize structural and species cover data for each type; stand tables serve as a reference for the countywide expression of vegetation, as well as plant palettes for future restoration efforts.

The vegetation inventory is compatible with the Midpeninsula Regional Open Space District’s (MROSD) Purisima Creek Redwoods vegetation inventory that was performed by AIS in 2005. The mapping area includes approximately 20,800 acres of coastal plain, foothills and mountains south of San Francisco in the Santa Cruz Mountains. Its western boundary roughly follows the mean high water line of the shore, and on the east by property boundaries near Skyline Boulevard along the summit of the Santa Cruz Mountains. The Northern boundary forms an edge to the previously mapped Purisima study area just south of highway 84. The southern boundary is located just north of the Cloverdale Coastal Ranches. Included in the study area are several ranches, including Pomponio and Michelson Ranch, both in the eastern portion of the mapping area. Several state parks are adjacent or nearby the mapping area and include Big Basin Redwoods & Butano State Park, Pescadero and Bean Hollow State Beaches, and Memorial & Pescadero Creek County Parks.78487:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78487Sun, 16 Apr 2023 14:50:34 -07002007-06-29T00:00:00Vegetation Classifcation and Mapping Report - This chapter of the Biotic Inventory report describes existing plant associations and their relation to soil and hydrology conditions of a portion of the Fish Slough Area of Critical Environmental Concern (including all of CDFW's Fish Slough Ecological Reserve.76470:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=76470Sun, 16 Apr 2023 14:39:45 -07001991-01-01T00:00:00Vegetation Classifcation and Mapping Report - Although the Santa Clara River riparian corridor is relatively intact, flood protection infrastructure, diversions, roads, agriculture, and urbanization have constrained or disrupted natural geomorphic and hydrologic processes, causing riparian and aquatic habitat degradation. While a number of studies and planning efforts have begun on the river to address these issues (e.g., Trustee Council 2002, AMEC 2005, and the Santa Clara River Parkway project), baseline information on existing riparian community types, their extent, and distribution is not available. Since native riparian vegetation provides critical ecosystem services, such as improved flood control and water quality, improved terrestrial and aquatic habitat quality, and increased local biodiversity, managing for healthy riparian vegetation is a central part of river management and restoration. Developing an accurate, current map of riparian vegetation is a crucial first step in river management and restoration planning This project addresses the need for detailed vegetation information in support of conservation and restoration planning efforts on the lower Santa Clara River within Ventura County. Funding for the project was provided through matching grants by the California State Coastal Conservancy (SCC) and The Santa Clara River Trustee Council (Trustee Council). The complex and dynamic nature of vegetation communities present within the lower Santa Clara River corridor required modifications to traditional approaches for riparian vegetation mapping; thus, this project utilized a combination of field-based vegetation classification and mapping, and traditional photo-interpretive techniques. The vegetation classification followed the State of California standard vegetation classification system developed under the auspices of the Vegetation Program of the California Native Plant Society and described in the first edition of A Manual of California Vegetation (Sawyer and Keeler-Wolf 1995), with minor adjustments to match changes being incorporated into the second edition of the Manual, which is currently in preparation (T. Keeler-Wolf, pers. comm., 2005 and 2007).76140:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=76140Sun, 16 Apr 2023 14:38:59 -07002007-08-01T00:00:00Vegetation Classification - The classification presented in this document has been replaced by The Survey of California Vegetation as the state's classification standard.

The Park is located in the Santa Monica Mountains of coastal southern California northwest of Los Angeles. It is a rugged mountain environment with many canyons and inland valleys. The vegetation types include riparian woodlands, oak woodlands, wetlands, chaparral, and coastal sage scrub. The park is a patchwork of federal, state, conservancy and private land holdings. Rural and suburban development occurs within and on the fringes of the park. Aerial Information Systems (AIS) was subcontracted by Environmental Systems Research Institute (ESRI), the prime contractor, to perform the vegetation photo-interpretation (PI) and automation for the program. NPS contracted with NatureServe and the California Department of Fish and Game for the development of the National Vegetation Classification System. The Park conducted the field sampling effort to support the development of the National Vegetation Classification System, as feedback for the photo interpreters, and to provide samples for Accuracy Assessment.72572:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=72572Sun, 16 Apr 2023 14:24:34 -07002007-05-23T00:00:00Vegetation Classifcation and Mapping Report - The California Native Plant Society (CNPS) Vegetation Program has produced a fine-scale vegetation map and monitoring data for the Carrizo Plain National Monument in conjunction with the US Bureau of Land Management and California Department of Fish and Wildlife. The vegetation map encompassed over 247,000 acres and was based upon 2007 true color one-foot resolution aerial imagery from San Luis Obispo County and 2010 natural color one-meter resolution digital imagery from Kern County. The minimum mapping unit (MMU) was 1 acre, with exceptions for wetland and other special types (0.5 acre MMU). The classification and map followed the National Vegetation Classification Standard and state of California Vegetation and Mapping Standards. The map includes 56 map unit codes, of which 48 are natural vegetation codes and eight are non-vegetated or exotic vegetation codes (e.g., cliffs and rock outcrops, developed, agriculture, exotic trees and shrubs). While the primary map attribute is vegetation type, additional map attributes include structural information (e.g., herbaceous, shrub and tree cover), and disturbance and site quality information. This report provides a summary of the mapping and field sampling methods, vegetation classification, results, and accuracy assessment that meets an overall accuracy of over 80%. The fine-scale vegetation map and supporting field survey data provide baseline information for long-term land management, conservation, and wildlife protection within the Carrizo Plain National Monument. 70311:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=70311Sun, 16 Apr 2023 14:21:33 -07002013-01-01T00:00:00Vegetation Classification and Mapping Report - This report describes sampling, classification, and mapping of Central California Sycamore Alluvial Woodland.63806:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=63806Sun, 16 Apr 2023 12:27:16 -07001997-05-01T00:00:00Vegetation Mapping Report - The Geographical Information Center (GIC) at California State University, Chico has completed a map of the natural vegetation of previously unmapped portions of Butte, Yuba, Sutter, Placer and Sacramento Counties with funding from the Strategic Growth Council (SGC).

This is the transcript of the webinar199106:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=199106Tue, 01 Mar 2022 14:03:04 -08002021-12-07T00:00:00Vegetation Mapping Report - Napa County has used a 2004 edition vegetation map produced using the Manual of California Vegetation classification system (Thorne et al. 2004 ) as one of the input layers for land use decisions and policy. The county decided to update the map because of its utility. The earlier map used black and white digital orthophoto quadrangles from 1993, with a pixel resolution of 3 meters. This updated version uses a 2016 edition of 1 meter color aerial imagery taken by the National Agriculture Imagery Program (NAIP; https://www.fsa.usda.gov/programs-and-services/aerial-photography/imagery-programs/naip-imagery/index) as the base imagery. It therefore permits an assessment of the change in the patterns of vegetation over 23 years in the county.174943:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174943Tue, 11 Jan 2022 15:19:11 -08002019-01-01T00:00:00Vegetation Classifcation and Mapping Report - Under contract to the U.S. Bureau of Land Management (BLM), Aerial Information Systems (AIS) created a fine-scale vegetation map of portions of the Mojave and Sonoran Deserts in California. AIS subcontracted the California Native Plant Society (CNPS) to conduct classification development work needed for this project, as well as accuracy assessment (AA) field data collection. The California Department of Fish and Wildlife’s (CDFW) Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate and score the AA. The mapping study area consisted of approximately 1,016,668 acres, spanning the desert portions of Inyo, Kern, and Imperial Counties were mapped between 2018 and 2020 within the Desert Renewable Energy Conservation Plan (DRECP) area. The primary purpose was to develop an accurate vegetation map for portions of the California desert as it pertains to renewable energy sources and conservation opportunities, helping planners identify high quality habitat and rare communities. The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on new and previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of 2016 or 2018 one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a 1 or 5 acre MMU, depending on type) and areas characterized as Land Use polygons (which were mapped to a 2.5 acre MMU). In the progression to non-desert areas the MMU transitioned to 1 acre for upland types and 1/4 acre for special types. Field reconnaissance and accuracy assessment enhanced map quality. There were a total of 126 mapping classes. The overall accuracy assessment ratings for the final vegetation map were 86.23 percent for User’sAccuracy, and 87.9 for Producer’s Accuracy187919:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=187919Fri, 15 Oct 2021 08:54:29 -07002020-12-01T00:00:00Vegetation Mapping Report - The original Dos Palmas Conservation Area 2013 status vegetation map and report were completed in 2016. The report and related map describe a map correction for the 2013 map as well as an updated map for the year 2018 covering the approximately 25,800 acres that comprise the Dos Palmas Conservation Area. Within the study areas, rapid assessment protocol vegetation plots, basic vegetation assessment plots and supplemental reconnaissance observations were obtained within the study at pre-determined points in order to document the plant community,disturbances, and invasive species across space and types. Heads-up photo-interpretation of 2013 local flight true-color imagery, fine-scale National Agriculture Imagery Project (NAIP) imagery (USDA, 2012, 2014, 2016 and 2018), other 2018 imagery and field information were combined to produce delineations of vegetation alliances and associations according to the California Department of Fish and Wildlife classification system, outlined in the Manual of California Vegetation (MCV) Second Edition (Sawyer et al. 2009). The first version of the Dos Palmas map was completed in 2016, however, the map will be referred to as a corrected 2013 map to match the imagery date, and further detail about the4 original map is contained in that report (Sweet et al. 2017). For the 2018 map update, additional field data was collected in 2018, which was incorporated into the both the 2013 map correction(as appropriate) and the 2018 map update. The 2018 map delineation was done by photointerpretation of updated imagery, with a focus on stand changes, mortality, cover and land use changes, and other anthropogenic changes. One hundred ninety-one partial Rapid Assessment plots were conducted in 2015-2016 within the study area, and an additional 222 Rapid Assessments were completed in 2018, plus additional reconnaissance field information that was collected.138027:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=138027Fri, 01 Jan 2021 13:19:42 -08002019-09-01T00:00:00Special Status Plants - Explains how the special status plants table in the 2nd edition of the Biodiversity Atlas was created.184756:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=184756Thu, 19 Nov 2020 15:26:55 -08002020-11-19T00:00:00Vegetation Mapping and Accuracy Assessment - 174866:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174866Fri, 24 Jul 2020 13:37:02 -07002019-11-01T00:00:00Vegetation sampling report - In keeping with the monitoring focus of the Suisun Marsh Vegetation Surveys (Keeler-Wolf and Vaghti 2000), in 2006, 100 of the original 198 Suisun Marsh vegetation plots were selected to be revisited for the first time since their establishment in the summer of 1999. To enable regular re-sampling into the future without any access issues, only those plots located on DFG land, Rush Ranch, or other publicly-accessible lands were considered for resampling. Of these plots, 100 were selected by the DFG Vegetation Classification and Mapping Program to capture the diversity of vegetation types that represent the Marsh’s vegetation as a whole. Due to the construction of the new Benicia-Martinez Bridge, two of the selected 100 plots are no longer in existence. Therefore, 98 plots were resampled (Figure 1). Each plot was located based on careful interpretation of GPS coordinates, field sample photos, aerial photos, and plot descriptions provided in the original 1999 field data. This report compares the original 1999 samples and the 2006 resamples with regard to the following characteristics: • Vegetation type as identified using the key developed from the 1999 field samples as displayed in Keeler-Wolf and Vaghti (2000); •Top three dominant species comparison from 1999 to 2006; •Shifts in non-native species composition; and •Basic shifts in floristic diversity and water cover. 178572:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=178572Wed, 22 Apr 2020 17:05:36 -07002007-02-01T00:00:00Vegetion Plot Resampling - In 1999 the DFG Vegetation Classification and Mapping program identified 198 vegetation sampling plot locations within the Suisun Marsh to be surveyed in order to create a vegetation classification to support the Suisun Marsh triennial vegetation map, as well as to establish baseline vegetation data that can be monitored over time (Keeler-Wolf and Vaghti, 2000). Since then, some portion of the established plots has been resampled every 6 years. In 2006, 98 out of the 198 plots were resampled and compared to the 1999 plot data to determine changes. The documents reporting those findings can be obtained from the California Department of Fish and Wildlife document library (http://www.dfg.ca.gov/biogeodata/vegcamp/veg_classification_reports_maps.asp). The purpose of this report is to document the methods and findings from the 2012 resampling of 98 of the original 198 vegetation sampling plots within Suisun Marsh and to show the trends of changes in the vegetation from 1999 to 2012 within those plots. 178571:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=178571Wed, 22 Apr 2020 17:00:17 -07002012-12-01T00:00:00Vegetation Classifcation and Mapping Report - The project consisted of installation-wide vegetation classification and mapping for Naval Base Ventura County (NBVC) Point Mugu, California. HDR conducted a vegetation assessment and sampling to obtain information necessary for land use and management decisions in support of military training activities, and facilities development and maintenance. Vegetation classification and mapping was carried out using the National Vegetation Classification Standard (NVCS) and the California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program. Plant nomenclature follows that of Baldwin et al. (2012). Surveys were conducted during four survey periods between January and July 2012, and were timed and spaced to avoid sensitive species, particularly birds, during the breeding and nesting seasons. 115571:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=115571Wed, 27 Nov 2019 10:41:04 -08002014-01-01T00:00:00Vegetation Mapping Report - The University of California Berkeley Herbarium contracted Aerial Information Systems, Inc. in 2008 to create a baseline inventory of wetlands and associated upland vegetation for approximately 38 square miles of land north of the city of Livermore, California, including and adjacent to the Springtown Alkali Sink Preserve. The vegetation map adheres to the 2008 National Vegetation Classification Standard (NVCS) and the Manual of California Vegetation. The complete mapping effort is divided into two phases. The first phase is the detailed mapping of several focus study areas which total approximately 4200 acres in size and include the Springtown Preserve and adjacent areas along with Brushy Peak and the upper Altamont Creek drainage. The Phase II portion involves the creation of a more generalized vegetation map for the remaining thirty square miles including much of the remaining Altamont Creek watershed in the northern portion of the Livermore Valley. The final vegetation map will serve multiple interests and will seek to provide the following: • Baseline inventory of existing vegetation • Baseline for monitoring change • Conservation & management planning needs • Addressing issues of increased alkalinity and expansion of Saltgrass habitat174996:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174996Wed, 06 Nov 2019 12:09:42 -08002009-11-01T00:00:00Vegetation Classifcation and Mapping Report - The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) has created a fine-scale vegetation map of the Department’s mitigation lands in the northern portion of the Carrizo Plain, San Luis Obispo County, California. The mapping follows Survey of California Vegetation, Federal Geographic Data Committee (FGDC), and National Vegetation Classification (NVC) standards (FGDC 2008, Jennings et al. 2009). The map legend is based on the classification in Stout et al. (2013), with slight modifications as discussed in Appendix C. Reconnaissance-level sampling of vegetation stands in the project area was conducted in the spring of 2013. Polygons were drawn using heads-up digitizing using the July 2011 1-foot imagery acquired for San Luis Obispo County and downloaded from US Geological Survey (USGS) EarthExplorer as the map base. Supplemental imagery included National Agricultural Imagery Program (NAIP) true color and color infrared (CIR) 1-meter resolution data from 2010–2012, Bing imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is ½ acre in order to capture small, remnant native stands of trees, shrubs, and bunch grasses. Mapping is to the NVC hierarchy Association, Alliance, or Group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. Field verification data was collected in the spring of 2014 and corrections were made to the map based on that data to increase the final accuracy. 92969:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=92969Fri, 01 Feb 2019 08:50:42 -08002015-01-01T00:00:00Vegetation Classifcation and Mapping Report - The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation classification and map of the southern addition to the CDFW Knoxville Wildlife Area , Napa County, California following State Vegetation Survey, Federal Geographic Data Committee (FGDC), and National Vegetation Classification (NVC) standards (Grossman et al 1998). The vegetation classification was derived from data collected in the field during the periods November 18–20, 2013 and April 28–May 1, 2014. Vegetation polygons were drawn using heads-up “manual” digitizing using the 2011 Napa County 30-cm resolution color infrared (CIR) imagery as the base imagery. Supplemental imagery included National Agricultural Imagery Program (NAIP) true color and CIR 1-meter resolution data from 2009–2012, BING imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is 1 acre, with the exception of wetland types, which have an MMU of ½ acre. Ponds, riparian types, and the one vernal pool on the WA that were visible on the imagery were mapped regardless of size, and streams were generally mapped if > 10 meters wide (narrower portions may have been mapped to maintain the continuity of the streams). Mapping is to the NVC hierarchy association, alliance, or group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. Both the existing (northern) and new addition (southern) portions of the Knoxville WA were mapped in 2002 as part of the Napa County vegetation map (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=14660). The 2014 map update was undertaken for two reasons: the 2002 map is at a coarse thematic resolution (alliance through macrogroup level), and vegetation in portions of the Wildlife Area has changed since the 2004 Rumsey Fire. We have produced an updated version of the 2002 map layer that uses the same spatial data, but adds a crosswalk to the current classification and the upper levels of the current hierarchy. This map layer is included in the download of the dataset from BIOS. 164824:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164824Fri, 01 Feb 2019 08:45:06 -08002014-10-01T00:00:00Vegetation Crosswalk Report - This map of the northern (existing) and southern (new acquisition) portions of the Knoxville Wildlife Area is a subset of the vegetation map and classification produced for Napa County in 2002 (Thorne et al 2004), which used the classification standards as described in the 1995 Manual of California Vegetation (Sawyer and Keeler-Wolf 1995) and followed the National Vegetation Classification Standard (NVCS) of the time. This map includes both the vegetation type as mapped in 2002 and the corresponding vegetation type as defined in an updated and finer-scale classification that was produced in 2014 by the Vegetation Classification and Mapping Program (VegCAMP). The updated classification was used for a fine scale map of the southern portion of the Wildlife Area. The base imagery used for photointerpretation for this map was the 1993 Digital Orthophoto Quarter Quads for Napa County. The full 2002 Napa County map can be found on BIOS (Vegetation – Napa County and Blue Ridge Berryessa [ds201]) and the associated report can be found here: http://www.nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=14660 (Thorne et.al 2004). The 2014 vegetation map and associated report for the Knoxville Wildlife Area can be obtained from the California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP). 164825:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164825Fri, 01 Feb 2019 08:44:12 -08002014-10-01T00:00:00Vegetation classification, description and key - This report describes 118 alliances and 212 associations that are found in Sonoma County, California. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification is the basis for an integrated, countywide vegetation map that the Sonoma County Vegetation Mapping and Lidar Program expects to complete in 2017.This report is divided into two volumes. Volume 1 is composed of the project introduction, methods, and results. It includes a floristic key to all vegetation types, a table showing the full local classification nested within the USNVC hierarchy, and a crosswalk showing the relationship between this and other classification systems. Volume 2 (this volume) provides descriptions of all vegetation alliances and associations. It summarizes distributional, structural, environmental, and plant species data for each type. Selaginella bigelovii was changed to S. wallacei in the January 2019 version of this report.115808:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=115808Fri, 25 Jan 2019 10:19:26 -08002015-12-01T00:00:00classificationVegetation classification - This spreadsheet lists Terrestrial Natural Communities per Robert Holland's 1986 Department of Fish and Game publication, "Preliminary Descriptions of Terrestrial Natural Communities of California." The full document, with descriptions, can be found here: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=75893 Please note that this classification has been replaced by the state's new standard as provided by the Vegetation Classification and Mapping Program. This list is made available for use in portions of the state that have not yet been classified and/or mapped. Types that were considered high priority for inventory (rare) in 1986 are denoted by an "x" in the second column. Sorting the list by the code in the third colulmn provides Holland's original bio-geo-physiognomic order.162503:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=162503Wed, 05 Dec 2018 16:05:20 -08001986-01-01T00:00:00Vegetation Mapping Report - The University of California Riverside’s Center for Conservation Biology (CCB) has created fine-scale vegetation maps for a number of Conservation Areas under the jurisdiction of the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) under contract with the Coachella Valley Conservation Commission (CVCC). The primary purpose for creating these maps is provide a landscapescale approach to monitoring changes due to land use, invasive species, recreation, hydrology, and climate. These digital maps, documenting changes and their causes, are then tools for prioritizing future conservation actions. The vegetation classification follow Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS; Federal Geographic Data Committee 2008). The classification is meant to align with previous and concurrent efforts previous survey and classification work done by California Department of Fish and Wildlife's Vegetation Classification and Mapping Program (VegCaMP) and Aerial Information Systems (AIS) for the Desert Renewable Energy Conservation Plan Area as well as the southeastern Salton Sea Mid-Desert Area, and by the National Park Service for Joshua Tree National Park. This map and report addresses the Coachella Valley Stormwater Channel and Delta Conservation Area (4,404 acres). Fieldwork, photo-interpretation and mapping were performed from 2016-2017. Within the study areas, rapid assessment protocol vegetation plots and supplemental reconnaissance observations were obtained within the study at pre-determined points in order to document the plant community, disturbances, and invasive species across space and types. Photo-interpretation of 2013 imagery and field information were combined to produce delineations of vegetation alliances and associations according to the California Department of Fish and Wildlife classification system, outlined in the Manual of California Vegetation Second Edition (Sawyer et al. 2009). Thus, the current version of the map best represents the status of vegetation in 2013. We digitized the vegetation of the Coachella Valley Stormwater Channel and Delta Conservation Area from 2013 imagery provided by the Coachella Valley Association of Governments (CVAG); it includes approximately 316 delineated polygons, each assigned one of 18 vegetation alliances or land-cover types. We assigned the still finer scale association attribute where field plot data (Rapid Assessment Plot or reconnaissance observation) was available within the polygon boundaries, or where the association could be clearly identified from aerial imagery. This unit has several map classes that have less than 2% absolute vegetation cover, including Disturbed/Built-Up, Water, and a generic Non-Vegetated Habitat type. The largest amount of land cover is of the non-vegetated habitat type, encompassing 1153 acres 467 ha), followed by iodine bush scrub (1040 acres, 421 ha), and Tamarix thickets (818 acres, 331 ha).162304:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=162304Mon, 26 Nov 2018 11:11:55 -08002017-06-01T00:00:00Vegetation Mapping Report - The University of California Riverside’s Center for Conservation Biology (CCB) has created fine-scale vegetation maps for a number of Conservation Areas under the jurisdiction of the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) under contract with the Coachella Valley Conservation Commission (CVCC).

The program will also create a geographic information system (GIS) database for the parks under its management. The purpose of the data is to document the state of vegetation within the NPS service area during the 1990's, thereby providing a baseline study for further analysis at the Regional or Service - wide level. The vegetation units of this map were determined through stereoscopic interpretation of aerial photographs supported by field sampling and ecological analysis. The vegetation boundaries were identified on the photographs by means of the photographic signatures and collateral information on slope, hydrology, geography, and vegetation in accordance with the Standardized National Vegetation Classification System (October 1995). The mapped vegetation reflects conditions that existed during the specific years and seasons that the aerial photographs were taken. Several sets of aerial photography were utilized for this project: 1) NOAA 1:24,000 March 1994 Natural Color Prints (Leaf Off) covering Point Reyes NS, the northern portion and southern coastal portions of Golden Gate NRA, and the western two thirds of Mt. Tamalpais State Park; 2) Pacific Aerial Survey 1:24,000 August 1995 Natural Color Prints (Leaf On) covering the southern portions of Golden Gate NRA and the San Francisco Watershed district; 3) Pacific Aerial Survey 1:24,000 November 1995 Natural Color Prints (Leaf Change) covering Samuel P. Taylor State Park and portions of the GGNRA; 4) 1:36,000 August 1991 Natural Color Prints (Leaf On) covering the eastern portion of Mt. Tamalpais State Park; 5) 1:12,000 August 1990 Natural Color Prints (Leaf On) covering Samuel P. Taylor State Park. (Supplemental data set - not interpreted off of); 6) 1:12,000 June 1993 Natural Color Prints (Leaf On) covering coastal portions of Mt.

This map and report were prepared for the Coachella Valley Multiple Species Habitat Conservation Plan (MSHCP) under contract with the Coachella Valley Conservation Commission (CVCC). The Mecca Hills and Orocopia Mountains final vegetation map, ecological descriptions, classification, and report, were completed in 2015. Initial mapping began with photo-interpretation and field work in 2013 and 2014, with additional work continuing until 2015. One hundred eighty-six reconnaissance vegetation assessment plots were conducted within the study area. Photo-interpretation of 2013 imagery was completed in October 2015 and match the most recent vegetation classification presented in the Manual of California Vegetation Second Edition (Sawyer et al. 2009). Thus, the current version of the map best represents the status of vegetation in 2013.138028:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=138028Mon, 30 Jan 2017 12:19:06 -08002015-12-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc (AIS) was contracted to create both a baseline vegetation map derived from 1990s-era imagery and an updated 2010 vegetation map for the Santa Lucia Preserve (Preserve) and neighboring properties to the west, for a total area of 25,630 acres. The neighboring properties are contiguous with the western boundary of the Preserve and are owned by several different organizations. These adjacent properties are: Whisler-Wilson Ranch, Palo Corona Regional Park, both owned by Monterey Peninsula Regional Park District (MPRPD); Mitteldorf Preserve, owned by Big Sur Land Trust (BSLT); a small portion of the Joshua Creek Canyon Ecological Reserve, which is the property of the California Department of Fish and Wildlife (DFW); and several pieces of private property owned by individuals. The vegetation mapping classification created for the project area is based on a floristic vegetation classification according to the National Vegetation Classification (NVCS) and on California statewide vegetation mapping and classification standards.137138:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=137138Thu, 12 Jan 2017 09:26:39 -08002013-04-01T00:00:00Vegetation Map Accuracy Assessment Report - The California Native Plant Society (CNPS) Vegetation Program conducted an independent accuracy assessment of a new vegetation map completed for the natural lands of Orange County in collaboration with Aerial Information Systems (AIS), the California Department of Fish and Wildlife (CDFW), and the Nature Reserve of Orange County (NROC). This report provides a summary of the accuracy assessment allocation, field sampling methods, and analysis results; it also provides an in-depth crosswalk and comparison between the new map and the existing 1992 vegetation map. California state standards (CDFW 2007) require that a vegetation map should achieve an overall accuracy of 80%. After final scoring, the new Orange County vegetation map received an overall user’s accuracy of 87%. The new fine-scale vegetation map and supporting field survey data provide baseline information for long-term land management and conservation within the remaining natural lands of Orange County.110882:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=110882Mon, 30 Nov 2015 10:26:11 -08002015-05-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc. (AIS) was contracted by the Nature Reserve of Orange County (NROC) to create an updated fine-scale regional vegetation map consistent with the California Department of Fish & Wildlife (CDFW) classification methodology and mapping standards. The mapping area covers approximately 86,000 acres of open space and adjacent urban and agricultural lands including habitat located in both the Central and Coastal Subregions of Orange County. The map was prepared over a baseline digital image created in 2012 by the US Department of Agriculture – Farm Service Agency’s National Agricultural Imagery Program (NAIP). Vegetation units were mapped using the National Vegetation Classification System (NVCS) to the Alliance level as depicted in the second edition of the Manual of California Vegetation (MCV2).110865:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=110865Mon, 30 Nov 2015 10:25:58 -08002015-04-01T00:00:00Vegetation Classification and Mapping Report - This report details the methods and results of a vegetation sampling and classification project undertaken in Yosemite National Park beginning in 1996. The goal of this project was to create a classification of the vegetation in and around Yosemite NP that was compliant with the National Vegetation Classification System and that could provide a basis for mapping the vegetation of the park15601:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=15601Tue, 30 Jun 2015 16:23:21 -07002012-06-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc. (AIS) was contracted by the Western Riverside County Regional Conservation Authority to perform an update to their original 2005 Western Riverside Vegetation Map. The project was funded through a Local Assistance Grant from the California Department of Fish and Wildlife (CDFW). The original vegetation layer was created in 2005 using a baseline image dataset created from 2000/01 Emerge imagery flown in early spring. The original map has been used to monitor and evaluate the habitat in the Western Riverside County Multi-species Habitat Conservation Plan (MSHCP). An update to the original map was needed to address changes in vegetation makeup that have occurred in the intervening years due to widespread and multiple burns in the mapping area, urban expansion, and broadly occurring vegetation succession. The update conforms to the standards set by the National Vegetation Classification System (NVCS) published in 2008 by the Federal Geographic Data Committee. (FGDC-STD-005-2008, Vegetation Subcommittee, Federal Geographic Data Committee, February 2008.) The update also adheres to the vegetation types as represented in the 2008-second edition of the Manual of California Vegetation (MCV2). Extensive ground based field data both within and nearby the western Riverside County mapping area has been acquired since the completion of the project in 2005. This additional data has resulted in the reclassification of several vegetation types that are addressed in the updated vegetation map. The mapping area covers 1,017,364 acres of the original 1.2 million acres mapped in the 2005 study. The new study covers portions of the Upper Santa Ana River Valley, Perris Plain, and the foothills of the San Jacinto and Santa Ana Mountains but excludes US Forest Service land. The final geodatabase includes both an updated 2012 vegetation map and a retroactively corrected 2005 vegetation base layer. Vegetative and cartographic comparisons between the newly created 2012 image-based map and the original vegetation map produced in 2005 are described in this report. 101084:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=101084Thu, 11 Jun 2015 13:20:25 -07002015-03-01T00:00:00Vegetation Mapping and Accuracy Assessment - The California Department of Water Resources (CDWR) is tasked with developing critical components of the Central Valley Flood Protection Plan (CVFPP). To further this effort CDWR collaborated with the California Department of Fish and Wildlife (DFW) and the California Native Plant Society (CNPS), and contracted with the Geographical Information Center (GIC), California State University, Chico, to develop a highly detailed vegetation classification system and a fine-scale vegetation map of the Central Valley Flood Protection Plan area within the Great (Central) Valley.74420:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=74420Wed, 20 May 2015 16:03:35 -07002013-10-01T00:00:00AccuracyAssessmentVegetation Map Accuracy Assessment Report - The Vegetation Classification and Mapping Program assessed the accuracy of the medium-scale (i.e., NVCS Group level) vegetation map of the Central Valley Flood Protection Planning mapping area produced by the Geographical Information Center (GIC) at CSU Chico.For the assessed map units with at least 8 surveys per type, the overall binomial user’s accuracy score averaged 76% and producer’s accuracy averaged 79%. Since the preferred accuracy for vegetation mapping products is 80% (See Article 4 in LAO Supplemental Report of the 2007 Budget Act, Item 3600-001-0001 – Dept. of Fish and Game ), the map almost met the map accuracy criteria. Those vegetation map units that did not meet the 80% expectation are reviewed here and additional suggestions for changes or improvements are discussed.72037:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=72037Wed, 20 May 2015 15:13:39 -07002011-01-01T00:00:00Vegetation Map Accuracy Assessment Report - an accuracy assessment effort with field verification was conducted by the California Department of Fish and Wildlife Vegetation Classification and Mapping Program (VegCAMP) staff of the East Sacramento Valley Natural Vegetation Map. For the assessed map units, the overall users’ accuracy averaged 90.2% and producers’ accuracy averaged 88.8%. Since the preferred accuracy for fine-scale vegetation mapping products is 80%, the map exceeded the standard overall, and did not meet the standard in only two classes, the Baccharis pilularis Alliance (78%) and Robinia pseudoacacia Semi-natural Stands (71%).58678:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=58678Wed, 20 May 2015 15:10:34 -07002013-01-16T00:00:00Vegetation Mapping Report - The National Park Service (NPS), in conjunction with the Biological Resources Division (BRD) of the U.S. Geological Survey (USGS), has implemented a vegetation mapping program to develop a uniform hierarchical vegetation methodology at a national level. The program also creates a geographic information system (GIS) database for the parks under its management. The purpose of the data is to document the state of vegetation within the NPS service area, thereby providing a baseline study for further analysis at the Regional or Service-wide level. Sequoia and Kings Canyon National Park (SEKI, Park) was selected as a post-prototype Inventory and Monitoring Program (IMP) mapping project. SEKI is part of the NPS Western Region and is located in the southern Sierra Nevada range of California. Sequoia National Park (SEQU) was established in September of 1890 and includes the Mineral King Valley and Mt. Whitney within the park boundaries. Kings Canyon National Park (KICA) was officially created in 1940. It absorbed the much smaller General Grant National Park created in 1890 to protect the Grant Grove of giant sequoias and includes backcountry wilderness and the South Fork of the Kings River. While SEKI is technically composed of two separate national parks, they are managed as one entity. Together they total 865,256 acres. The Park elevations range from 1,300 feet in the Sierra foothills to 14,491 feet atop Mt. Whitney. The vegetation includes riverine woodlands, wetlands, chaparral, hardwood and coniferous forests, meadows, and above-timberline vegetation. The park ecosystems include the full range of montane, subalpine, and alpine environments, including permanent snowfields and glaciers. Aerial Information Systems (AIS) was subcontracted by Environmental Systems Research Institute (ESRI), the prime contractor, to perform the vegetation photo interpretation and automation for the SEKI project. Staff ecologists at Sequoia and Kings Canyon National Park conducted the field sampling effort to support development of the National Vegetation Classification System (NVCS), to provide feedback for the photo interpreters, and to assess the accuracy of the cartographic map products. 88515:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=88515Thu, 14 May 2015 13:34:08 -07002007-01-24T00:00:00Inventory report - A summary of the current statewide body of knowledge for vernal pools.

The information is represented as GIS coverages that allow for further geographic analysis, revisions and updates. Arctostaphylos myrtifolia is federally listed as threatened and listed as endangered in California. Eriogonum apricum var. apricum (Ione buckwheat) and Eriogonum apricum var. prostratum (Irish Hill buckwheat) are both listed federally and by the State of California as endangered. Pinpointing the distribution of these endemic species provides information for more effective planning and habitat conservation for their future recovery and survival. An accuracy assessment of the GIS map of vegetation was performed to estimate the correctness of the mapped vegetation classification. Fifty random plots were located and surveyed within the study area. Surveyed plots were compared with their location on the map and the vegetation class assigned on the map was compared to that determined by ground survey. Thirty survey plots were taken within the A. myrtifolia community using a releve method to obtain a clearer, more quantitative description of the community. An estimate of cover, species composition and abundance were recorded for each plot. Additionally, there has been a considerable amount of A. myrtifolia dieback noted in the past few years. This study provides a quantitative and spatial measurement of how much dieback currently exists and investigates the causal agents for the decline. The pathogens involved are identified and the potential methods of management appropriate to improve the health and survival of the Ione chaparral are suggested.96009:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=96009Fri, 27 Mar 2015 12:19:18 -07002004-09-01T00:00:00standardsVegetation mapping standards - The core and optional vegetation attributes required for a map to meet state standards.93414:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=93414Tue, 03 Feb 2015 15:03:06 -08002003-01-01T00:00:00Vegetation Classification and Mapping Report - The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) has created a fine-scale vegetation map of part of the range of the American Ranch and Chimineas Ranch tule elk herds. This section of the elk range is adjacent to the Carrizo Plain National Monument and the Chimineas Ranch Unit of the Carrizo Plain Ecological Reserve, both of which have been previously mapped. This map has been seamed to the vegetation map of the Chimineas Ranch completed by VegCAMP (VegCAMP 2010) and the map of the Carrizo Plain National Monument produced by the California Native Plant Society (Stout et al. 2013), and completes the range of these two elk herds in San Luis Obispo County, California. Like those maps, this mapping follows Survey of California Vegetation, Federal Geographic Data Committee (FGDC), and National Vegetation Classification (NVC) standards (FGDC 2008, Jennings et al. 2009). The map legend is based on the classification in Stout et al. (2013), with slight modifications as discussed in Appendix C. Reconnaissance-level sampling of vegetation stands in the project area was conducted in the spring of 2013. Polygons were drawn using heads-up digitizing with true color 1-foot aerial imagery from August 1, 2007 as the map base. Supplemental imagery included National Agricultural Imagery Program (NAIP) true color and color infrared (CIR) 1-meter resolution data from 2010–2012, Bing imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is 1 acre, with the exception of wetland types, which have an MMU of ½ acre. Mapping is to the NVC hierarchy Association, Alliance, or Group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. Two sub-Group level mapping units were used in instances where the vegetation types could not differentiated on the imagery. The first mapping unit is composed of the Salvia leucophylla, Eriogonum fasciculatum, Artemisia californica, and Artemisia californica-Eriogonum fasciculatum Alliances; the second is composed of the Atriplex polycarpa and Atriplex canescens Alliances. Accuracy assessment (AA) data was collected in spring of 2014. Map accuracy was calculated to be 89%; corrections were made to the map based on the AA data to increase the final accuracy. 92951:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=92951Wed, 28 Jan 2015 09:05:19 -08002015-01-01T00:00:00reportsignificant natural areas - This document identifies and ranks unique wildlife ecosystems in California using national and regional guidelines per the Land and Water Conservation Fund Act of 1965 as amended in 1976. 91169:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=91169Fri, 14 Nov 2014 10:40:42 -08001978-01-01T00:00:00Historical Report - Nine quadrats along the Sacramento River were sampled for vegetation and avian use during August 1971.

Objectives were to: (1) survey, map and classify vegetation communities in order to produce a product that is consistent, repeatable, and translatable to regional/national levels; and (2) provide a vegetation community classification and resultant map based on a floristic vegetation classification to SNI. The vegetation map classes represented the association level of the NVCS except in the case of Mediterranean California Naturalized Annual and Perennial Grassland, which was mapped to the group level due to the heterogeneity of the species composition in these stands. A total of 17 vegetation classes were identified on SNI. Of these, 16 vegetation classes were mapped aboard the installation using a 0.10 hectare (0.25 acre) minimum mapping unit (MMU) for a total of 5,600.51 hectares (14,225.26 acres) mapped. Surveys were conducted within select vegetation communities during four sampling periods between February and April 2013. A total of 157 classification plots representing 17 vegetative communities were sampled.88543:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=88543Tue, 19 Aug 2014 15:20:58 -07002014-03-01T00:00:00Vegetation Classification and Mapping Report - The Vegetation Map of the Carrizo Plain Ecological Reserve, San Luis Obispo County, California was created by the California Department of Fish and Game (DFG) Vegetation Classification and Mapping Program (VegCAMP). Data from 379 vegetation Rapid Assessment surveys that were conducted from 2005-2008 was analyzed using cluster analysis to produce a vegetation and mapping classification for the 39,597-acre study area. The area was delineated and attributed by vegetation type; total cover; conifer tree, hardwood tree and total tree, shrub or herb cover; impacts present; and a subjective assessment of site quality using 2007 1-foot resolution base imagery. The classification and map follow the National Vegetation Classification Standard (NVCS) and Federal Geographic Data Committee (FGDC) standard and State of California Vegetation and Mapping Standards. The minimum mapping unit is one acre, with 0.5 acre for wetland or special types. After a draft map was completed, about half of the polygons were verified in the field, and polygons not visited were corrected if necessary. This metadata and mapping report serves to document the entire project.15231:8https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=15231Tue, 01 Apr 2014 15:13:40 -07002009-09-09T00:00:00Vegetation Classification and Mapping Report - The California Department of Fish and Game (Department) Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation classification and map of the Department’s Oak Grove property, San Diego County, California following FGDC and National Vegetation Classification Standards.

This classification was based on the first Manual of California Vegetation, but includes types not described there, nor compatible with MCV II.78485:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78485Mon, 10 Mar 2014 11:59:08 -07002000-04-10T00:00:00Vegetation Classification and Mapping Report - The following information is contained in this report: • A description of the mapping conventions and methodologies used to delineate and assign attributes to polygons for the vegetation map for the 36 properties (35 Marin County Open Space Preserves and 1 County Park) and surrounding land on MCOSD property (the 36 properties that were mapped can be found in Appendix C). • The descriptions for the MCOSD mapping types, which was initially based on the Marin Municipal Water District (MMWD) Vegetation Classification, jointly created by MMWD and California Native Plant Society (CNPS), then further refined for the MCOSD study area by field reconnaissance and plot data collection by MCOSD. • An area report of the study area, complete with the vegetation code, polygon count, acres, hectares and average polygon size (in acres). • A list of the fields used for attributing polygons in the final map. 73951:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=73951Thu, 03 Oct 2013 13:24:39 -07002008-07-07T00:00:00Vegetation Classification and Mapping Report - Between 2003 – 2008, the vegetation within a study area of 18,210 hectares (44,997 acres) that encompasses the Pinnacles National Monument (PINN), a quarter-mile buffer and several additional parcels of interest adjacent to the Park was mapped. The map was produced from photo interpretation of 2003 and 2005 natural color and 2002 color infrared digital 1 meter NAIP imagery orthophotos. In 2003 and 2004 Park staff collected vegetation and environmental data from 591 relevés to support the map and classification. Assessment of map accuracy entailed sampling of 766 additional data points in 2008. Multivariate analysis of the 2003-2004 plot data revealed 67 National Vegetation Classification (NVC) plant associations, alliances or Park special vegetation types within the Monument and environs. Of these, 45 are described at the plant association level; seven others are described at the alliance level. The remaining 22 are described as ‘Park specials’ because they occur only in small stands and appear to be unique to the Monument. The vegetation of the mapping project area is relatively diverse, including 50 NVC alliances. Chaparral, oak woodlands and dry herbaceous areas dominate the vegetation, accounting for ~35 associations. A total of 6,141 map polygons representing 34 vegetation map classes (including tree and shrub cover attributes), fourteen land use map classes and 7 miscellaneous classes were developed for the PINN vegetation mapping project. Of the 6,141 mapped polygons, 115 were assigned both a land use class and a vegetation class. The average polygon size across all map classes is 3 ha (7.3 acres). Natural and semi-natural vegetation classes cover 17,953 ha (44,362 acres), or 98.6% of the project area. Land use polygons, including ranch developments, agriculture and Park facilities cover 250 ha (617 acres), or 1.4 % of the project area. Final overall map Producer accuracy is 84.4% (Kappa correction = 83.1%). Final overall map User accuracy is 78.0% (Kappa correction = 75.6%).18212:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18212Thu, 11 Apr 2013 11:32:35 -07002009-06-01T00:00:00Vegetation Classification and Mapping Report - This report summarizes the findings based on data collection of vegetation in the inner South Coast Ranges of California in an approximately 100,000 acre area. In the spring and summer of 2004 to 2005, 570 vegetation rapid assessments were collected by a field crew of vegetation ecologists. In the fall and winter 2004-2005, these data were entered into a database and analyzed using multivariate statistical programs to develop a floristic classification, keys, and complete descriptions of all vegetation identified in the area. This project serves two complementary functions. The first is to develop a detailed vegetation inventory of this area to assist the Bureau of Land Management in developing long-range management decisions about this area which ranges from a wilderness study area to grazing, mining, and off-road vehicle use. The second is to provide a test case for the development of vegetation mapping methodologies to be recommended by the California State Vegetation Memorandum of Understanding Committee. The classification and descriptions produced herein will be used to develop detailed maps of the area’s vegetation. These maps will be created using two different techniques, and a comparison made between their accuracy and efficiency of production.18247:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18247Thu, 11 Apr 2013 11:31:45 -07002006-02-01T00:00:00Vegetation Classification and Mapping Report - A comprehensive plant community classification and mapping project for a 155,000 acre study area of National Park Service lands in San Francisco Area was conducted between 1997 and 2003. Eighty seven plant communities were described using 366 vegetation plots collected in the various habitats throughout the study area. The vegetation plots were also used as training data for photo interpreters to map plant communities using 1:24,000 true color photos. The Minimum Mapping Unit (MMU) was set at 0.5 hectares. Seventy-four plant community or mapping units were delineated using the aerial photographs. The accuracy, at the finest botanical level of resolution, varied by class from 0 to 100%. In addition to using the National Vegetation Classification System, we created a custom classification hierarchy based on ecological similarity as determined during an ordination analysis of the 366 training plots. This custom classification was used as the basis of a modified ‘fuzzy’(Congalton and Green 1999) approach for accuracy assessment. Overall thematic accuracy varied from 44% at the association level to 87% at the life form level.18209:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18209Thu, 11 Apr 2013 11:31:16 -07002003-07-30T00:00:00Vegetation Classification and Mapping Report - In 2011, the Chico Geographical Information Center (GIC), under contract to the Department of Water Resources, produced a Central Valley Riparian Vegetation map for the Central Valley Flood Protection Program. This document provides the mapping standard and land use categories for the Central Valley Riparian vegetation map.43372:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=43372Thu, 11 Apr 2013 11:29:01 -07002012-01-01T00:00:00Vegetation Classification and Mapping Report - The following report describes the vegetation classification and mapping of the Legal Delta portion of the Sacramento-San Joaquin River Delta conducted in 2005-2006 for use in conjunction with the Delta Regional Ecosystem Restoration Implementation Plan. The Legal Delta covers approximately 725,600 acres, of which approximately 104,600 acres are natural vegetation, 555,100 acres agriculture and urban development, and 65,900 acres are open water or inundated lands. Vegetation sampling by means of the CNPS Rapid Assessment Protocol was used to obtain a total of 377 Rapid Assessments, which were used to develop a quantitative classification based on cluster analysis. A total of 52 vegetation alliances were identified, which included an additional 45 defined plant associations. In combination, 95 finescale floristic classification units emerged from the analysis. These classification units were either directly or indirectly used to develop a combination of 129 fine-scale to mid-scale vegetation mapping units. Mapping was completed via heads-up digitizing, and each delineated polygon was coded with both a vegetation type and one of 25 land use types. Base imagery was true color 1-foot resolution aerial photography from spring 2002 with additional marginal areas of the study area supplemented by true color 1-meter resolution photography from summer 2005. This type of mapping approach was then compared with a more traditional finescale vegetation mapping product of Suisun Marsh to provide measures of efficiency and accuracy for future mapping efforts in the Bay-Delta Region.18211:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18211Thu, 11 Apr 2013 11:27:43 -07002007-02-01T00:00:00Vegetation Classification and Mapping Report - The Palos Verdes Peninsula Land Conservancy (PVPLC) received grant funding through the California Department of Fish and Game’s Local Assistance Grant program to produce a fine-scale, spatially and floristically accurate vegetation map of the Palos Verdes Nature Preserve (PVNP). The PVNP is part of the draft Rancho Palos Verdes Natural Community Conservation Plan (RPV-NCCP) area, and encompasses approximately 1200 acres of protected open space. The PVNP is located in the City of Rancho Palos Verdes, in southern Los Angeles County. The project area represents several biologically rare habitat types, including coastal sage and cactus scrub. In addition, the PVNP hosts several rare and endangered plant and animal species, which are classified as covered species in the RPV-NCCP. Vegetation resources were assessed through field surveys, resulting in the classification analysis of 26 vegetation alliances, 38 vegetation associations or semi-natural stands, and mapping of 583 vegetation map polygons.24567:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24567Thu, 11 Apr 2013 11:27:24 -07002010-01-01T00:00:00Vegetation Mapping Report - This document presents a summary analysis of the California GAP Land Cover data set (GAP) recently completed by the National Gap Analysis Program (GAP 2009; Lennartz 2008). The GAP data set models regional land cover for a wide range of purposes including estimating distribution of biological resources and regional conservation planning. The California GAP provides a relatively new statewide vegetation map. GIS (Geographic Information Systems) analysis methods applied by GAP are considered to produce better vegetation maps compared to previously state- or nation-wide products. Analyses presented here are an evaluation of the GAP’s utility in regional conservation planning, habitat change detection, and identifying potential restoration sites within the Central Valley Flood Protection Program (CVFPP) Systemwide Planning Area (project area). Three regions totaling over 1-million acres within the project area were selected for analyses based on availability of substantive and detailed digital land cover maps. These areas are: Sacramento River region 2007 Sacramento River Riparian Mapping (SRRM); 2010 CVFPP Feather River regional mapping (FRRM); and the 2007 Delta Region Department of Fish and Game Vegetation Map (Delta map). 43478:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=43478Mon, 05 Mar 2012 10:12:08 -08002011-01-01T00:00:00Vegetation Mapping - This report describes the GIS methods associated with the BIOS dataset ds160 (Vegetation - Suisun Marsh 1999). The process by which source data, i.e. aerial photography, its interpretations, and field observations becomes a final spatial data layer; viewable on computer screens, printable as a map, and capable of various types of summary reports, and analysis.42579:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=42579Thu, 16 Feb 2012 14:27:58 -08002000-01-01T00:00:00Vegetation Classification Report - This document provides background data for the Vegetation Classification Manual for Western San Diego County including detailed individual stand data. 28652:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=28652Wed, 30 Mar 2011 10:38:53 -07002011-02-01T00:00:00Vegetation Classification Report - The purpose of this manual is to describe each of the native and naturalized vegetation types known to occur within western San Diego County and to provide the user a means to determine each type through direct observations of species composition. The intended users of this manual are biologists, vegetation ecologists, geographers, land managers, regional planners, and all others for whom applying standardized nomenclature to vegetation is useful.

To enable regular re-sampling into the future without any access issues, only those plots located on DFG land, Rush Ranch, or other publicly-accessible lands were considered for resampling. Of these plots, 100 were selected by the DFG Vegetation Classification and Mapping Program to capture the diversity of vegetation types that represent the Marsh’s vegetation as a whole. Due to the construction of the new Benicia-Martinez Bridge, two of the selected 100 plots are no longer in existence. Therefore, 98 plots were resampled (Figure 1). Each plot was located based on careful interpretation of GPS coordinates, field sample photos, aerial photos, and plot descriptions provided in the original 1999 field data.24568:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24568Thu, 04 Nov 2010 13:13:39 -07002007-02-01T00:00:00Vegetation Classifcation and Mapping Report - The California Department of Fish and Game (CDFG) contracted with the California Native Plant Society (CNPS) and Aerial Information Systems (AIS) to produce an alliance-level vegetation classification and map of Western Riverside County, California. The resulting classification and map products will be used to help establish a monitoring basis for the vegetation and habitats of the Western Riverside County Multi-Species Habitat Conservation Plan (MSHCP). The plan aims to conserve over 500,000 acres of land out of the 1.26 million acre total. This area is the largest MSHCP ever attempted and is an integral piece of the network of Southern California Habitat Conservation Plans and Natural Community Conservation Planning (Dudek 2001, Dudek 2003). In the CNPS contract, vegetation resources were assessed quantitatively through field surveys, data analysis, and final vegetation classification. Field survey data were analyzed statistically to come up with a floristically-based classification. Each vegetation type sampled was classified according to the National Vegetation Classification System to the alliance level (and association level if possible). The vegetation alliances were described floristically and environmentally in standard descriptions, and a final key was produced to differentiate among 101 alliances, 169 associations, and 3 unique stands.18245:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18245Tue, 09 Mar 2010 16:06:51 -08002006-05-01T00:00:00Vegetation Classification Report - The U.S. Geological Survey (USGS) and National Park Service (NPS) formed a partnership in 1994 to map the vegetation of the United States National Park system units using The Nature Conservancy's National Vegetation Classification, a standard for reporting vegetation information among federal agencies (Grossman et al. 1998). Goals of the projects include providing baseline ecological information to resource managers in the parks; putting the data into regional and national contexts; and providing opportunities for future inventory, monitoring, and research activities. Each park developing a vegetation map follows a standardized field sampling and vegetation classification protocol to document the various vegetation types found in that park. This information is used by photointerpreters to delineate polygons of vegetation communities, which are subsequently subjected to an accuracy assessment process (USGS 1994). The final products consist of a vegetation map, descriptions of each vegetation type, a key to each type, and all related data and metadata files (original field forms, plot database, accuracy assessment points, etc.). This report presents the work at the Santa Monica Mountains National Recreation Area (NRA) (park code: SAMO) and environs conducted from 2001 to 2005.18243:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18243Tue, 09 Mar 2010 15:53:12 -08002006-01-01T00:00:00Vegetation Classification Report - The following report describing the vegetation of the northern Sierra Nevada Foothills was completed by the California Native Plant Society (CNPS) for the California Department of Fish and Game (CDFG). CDFG contracted with CNPS to identify the range of vegetation types in the northern Foothills by collecting field samples across the region in 2005 and 2006. The National Fish and Wildlife Foundation (NFWF) rewarded CNPS two sequential grants to involve volunteers in collecting vegetation samples across the Sierra Nevada Foothills in the same timeframe. Additional field samples collected in the study area by collaborators were used to develop this inventory. The northern Foothills region, here defined by the two northern subsections of the Sierra Nevada Foothills Section of the USDA Ecological Subregions of California (Miles and Goudey 1997), includes 2.48 million acres of land, with approximately 15% under public ownership and 85% under private ownership. Vegetation sampling by means of the CNPS Relevé and Rapid Assessment Protocols was used to obtain a total of 710 Relevés and 1691 Rapid Assessments, which were used to develop a quantitative classification based on cluster and indicator species analyses. The resulting classification describes vegetation types according to the National Vegetation Classification System, which is now the state standard. A total of 57 vegetation alliances and 8 semi-natural types were identified, which included an additional 156 defined plant associations and 3 sub-alliances. The rarity of these vegetation types was ranked by the CDFG Senior Ecologist.18236:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18236Tue, 09 Mar 2010 15:41:43 -08002007-12-01T00:00:00Vegetation Classification Report - The following report describing the vegetation of the northern Sierra Nevada Foothills was completed by the California Native Plant Society (CNPS) for the California Department of Fish and Game (CDFG).

The classification follows the National Vegetation Classification System’s hierarchy of alliances and associations. These are floristically and environmentally defined plant communities, such as those described in the CNPS publication of A Manual of California Vegetation (Sawyer and Keeler Wolf 1995). In this project, the vegetation types are depicted in standard descriptions and a field key to concisely differentiate 86 alliances, 2 unique stands, and 103 associations. In a parallel effort, the alliance and association-level classification is being used to create a vegetation map at a fine-scale resolution (minimum mapping unit of 1/2-1 acre). The map is being created by interpreting detailed, digital color aerial photography and delineating boundaries around the individual stands of vegetation in the study area. This detailed map is being produced in a Geographic Information System (GIS) digital format, through a “head’s-up” digitizing process. With the field data collected and classified, the mapping is guided by the 579 rapid assessments and 595 reconnaissance points. The final map will include digitization of polygons and attribution of the vegetation type, tree cover, shrub cover, herb cover, tree size, site quality and impacts.14652:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=14652Mon, 08 Mar 2010 10:42:54 -08002006-05-01T00:00:00Vegetation Classification Report - The Vegetation Program of the California Native Plant Society (CNPS) has worked collaboratively with the Marin Municipal Water District (MMWD) and Aerial Information Systems (AIS) to produce a fine-scale vegetation classification and map on MMWD lands. At least 55 different plant communities, described floristically at the alliance level of the National Vegetation Classification (Grossman et al. 1998), are discussed in this report. Two main project goals are 1) to provide detailed, floristic classification of the vegetation with a report defining the different vegetation types, 2) to provide a detailed vegetation map of the region. Field data are being collected using standard CNPS protocols (e.g., Vegetation Rapid Assessment and Relevé protocols). The field-based classification depicts vegetation types that were sampled in 419 CNPS Vegetation Rapid Assessments and Relevés by MMWD staff. The classification has been produced by CNPS using the National Vegetation Classification System’s hierarchy of alliances and associations. These are floristically and environmentally defined plant communities, such as those described in the CNPS publication of A Manual of California Vegetation (Sawyer and Keeler Wolf 1995). In this project, the vegetation types are depicted in standard descriptions and a field key to concisely differentiate 59 alliances and habitats, of which 88 associations are determined 16314:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=16314Mon, 08 Mar 2010 10:41:30 -08002006-01-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc. (AIS) was contracted by The Nature Conservancy to create a vegetation map covering approximately 42500 acres (~66 square miles) within the majority of the San Benito River Valley. The goal of the project is to create a baseline vegetation map depicting existing conditions within the study area. The vegetation map will be used by TNC for four primary purposes: • To track changes that may occur to vegetation and associated wildlife habitats over time. • To better understand the distribution of riparian vegetation types within the San Benito River system. • To contribute to building a better Statewide vegetation map on lands where TNC has a conservation interest. • To study connectivity of pristine habitats between the Gabilan and Diablo ranges in a rapidly urbanized area. 17942:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17942Wed, 17 Feb 2010 10:20:21 -08002007-06-29T00:00:00Vegetation Mapping Report - The Nature Conservancy (TNC) contracted AIS to develop a terrestrial vegetation map for the Salinas River in Monterey County with the main goal of the project being to create a baseline map of existing vegetation within the river floodplain. The mapping area is buffered approximately ¼ mile from the river channel, and includes vegetation along the tributaries of the Arroyo Seco, San Antonio and Nacimiento Rivers, in addition to several smaller tributaries. The vegetation map will be used by TNC to determine the extent of native riparian vegetation along the Salinas River and its major tributaries, to identify significant areas of invasive species such as Giant Cane, and to inform an assessment of potential wildlife corridors along the riparian corridor to the adjacent upland habitats in the coastal ranges. 17941:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17941Wed, 17 Feb 2010 10:15:52 -08002008-05-01T00:00:00Vegetation Mapping Report - Aerial Information Systems, Inc. (AIS) was contracted by The Nature Conservancy to create a vegetation map covering approximately 11000 acres (~17 square miles) known as the Gabilan Ranch south of the town of San Juan Bautista. The goal of the project is to create a baseline vegetation map depicting existing conditions within the study area. The vegetation map will be used by TNC for three primary purposes: • Track changes that may occur to vegetation and associated wildlife habitats over time. • To better understand the distribution of rare vegetation types not adequately mapped or described in existing classification systems • To contribute to building a better Statewide vegetation map on lands where TNC has a conservation interest.17939:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17939Wed, 17 Feb 2010 10:04:48 -08002006-10-01T00:00:00Vegetation Mapping Report - This reports details the mapping units that were created based on the NVCS-compliant vegetation classification of Yosemite National Park. Each mapping unit is described with respect to its relationship to the classification, a photo signature description is given along with other defining characteristics including slope, aspect, cover density. Example images from both the imagery and ground-based photographs are included.15602:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=15602Mon, 09 Nov 2009 11:57:07 -08002007-03-01T00:00:00Vegetation Classification Report - This project employed a representative sampling approach to develop a hierarchi~al classification of forest alliances and associations on the 172 km2 Whiskeytown National Recreation Area in Shasta County, California. Twenty alliances, thirty-nine associations, and ten "types" were found in the park. The positions of associations and vegetation polygons (sampling units) relative to each other along gradients of environmental variation were analyzed, and elevation was found to be the single most influential such gradient, followed by steepness of slope and moisture availability. The high number ofalliances and associations found at Whiskeytown supports previous conclusions about the Klamath Region's importance as a "center" of plant diversity for the American West Coast. Furthermore, Whiskeytown's vegetation complexity is even more complex than that ofmost ofthe rest ofthe Klamath Region. This points to the complex nature ofdisturbance dynamics in the area.16311:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=16311Mon, 09 Nov 2009 11:52:53 -08002003-05-14T00:00:00Vegetation Mapping Report - In 1995, the Manual of California Vegetation introduced a quantitatively based method for classifying and mapping vegetation in California. We used this method to develop a classification of vegetation types for Napa County, which we then used to attribute the polygons of a new vegetation map. The new map was produced by on-screen digitizing over USGS Digital Orthophoto Quarter Quads (DOQQ’s) with the aid of ancillary digital maps. We identified the distribution of 56 landcover types, 48 dominated by natural vegetation, at the alliance or aggregated alliance level, in 28,456 polygons across 2042 km2. The effective minimum mapping unit is below one hectare. The methods used, the mapping classification system developed, and the extents of landcover types mapped are presented. In a comparison with two previous digital vegetation maps for the area, the US Forest Service’s CalVeg and the Gap Analysis Program’s GAP maps, the MCV map had finer spatial and floristic resolution. The MCV map has 15 more vegetation types than CalVeg and 22 more vegetation types than GAP. The MCV map contains more riparian corridors and isolated wetlands, identifying 157 km2 of these types, compared to 7 km2 for CalVeg and a non-spatial result for GAP14660:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=14660Mon, 09 Nov 2009 11:37:44 -08002004-01-01T00:00:00Vegetation Classifcation and Mapping Report - Report detailing methods of surveying, classifiying, and mapping the vegetation of the Central Mojave region of California.
