The proposed site, Hatchet Ridge, is located approximately 6 miles west of Burney, California and along the primary ridgeline of Hatchet Mountain north of California State Highway 299. The proposed development would be located on private land and would consist of the installation, operation, maintenance, and eventual decommissioning of approximately 100 MW of turbines and supporting facilities. In support of the environmental impact evaluation for the project, a detailed 12-month biological resources study plan was developed and implemented at the site. The study protocol was developed in cooperation with the California Department of Fish and Game and the U.S. Fish and Wildlife Service and based on expertise and experience of WEST, Inc. studying wind power effects on birds and wildlife. Objectives of the study were to provide data that was useful in evaluating potential impacts from the proposed project and assist in siting of project facilities within the project area. The field surveys were designed to: (1) describe and quantify seasonal avian use of the proposed project area; (2) describe and quantify raptor use of the proposed project; (3) describe and quantify seasonal bat use of the proposed project; (4) describe vegetation types and rare plant occurrence in the proposed project area.23992:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23992Fri, 01 Oct 2010 13:43:13 -07002007-08-01T00:00:00WindEnergyWind energy biological data - The Diablo Winds Energy Project is located in Alameda County California. The project was completed in February 2005 and consists of 31 Vestas V47 turbines located on the Elworthy property in the central portion of the Altamont Pass Wind Resource Area. These turbines replaced 169 FloWind model F-17 and F-19 vertical axis turbines. The vertical axis Flowind turbines were removed in 2004, as were approximately 8 miles of overhead electrical line, one guyed 30-m (98-ft) met tower, and 36 18-m (60-ft) free-standing lattice met towers.23991:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23991Fri, 01 Oct 2010 13:39:08 -07002006-04-01T00:00:00WindEnergyWind energy biological data - Wind energy development in the Altamont Pass region of California peaked during the mid-1980s, when most of the wind turbine towers now in existence were erected (Hunt 1997). Since 1981, more than 7,000 wind turbines have been installed in the Altamont Wind Resource Area (WRA). Currently about 5,000 are operating, with that number being reduced as repowering continues. They are distributed over an area of approximately 150 km2 (Walcott 1995). In the Altamont WRA, wind speeds average 25?45 km/hr between April and September, when the facility produces 70% to 80% of its power. During winter, the wind speeds drop to 15?25 km/hr. In the summer months, wind speeds are generally sufficient to operate the turbines by mid-afternoon and well into the evening hours.23990:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23990Fri, 01 Oct 2010 13:35:56 -07002000-05-01T00:00:00WindEnergyWind energy biological data - Over the past 15 years, research has shown that wind turbines in the Altamont Pass Wind Resource Area (APWRA) kill many birds, including raptors, which are protected by the Migratory Bird Treaty Act (MBTA), the Bald and Golden Eagle Protection Act, and/or state and federal Endangered Species Acts. Early research in the APWRA on avian mortality mainly attempted to identify the extent of the problem. In 1998, however, the National Renewable Energy Laboratory (NREL) initiated research to address the causal relationships between wind turbines and bird mortality. NREL funded a project by BioResource Consultants to perform this research directed at identifying and addressing the causes of mortality of various bird species from wind turbines in the APWRA. With 580 megawatts (MW) of installed wind turbine generating capacity in the APWRA, wind turbines there provide up to 1 billion kilowatt-hours (kWh) of emissions-free electricity annually. By identifying and implementing new methods and technologies to reduce or resolve bird mortality in the APWRA, power producers may be able to increase wind turbine electricity production at the site and apply similar mortality-reduction methods at other sites around the state and country.23989:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23989Fri, 01 Oct 2010 13:32:43 -07002005-08-01T00:00:00WindEnergyWind energy biological data - This report presents the results of radar and visual studies of spring nocturnal bird and bat migration conducted from 16 April–30 May 2007 (primary sampling period) and 21–30 March 2007 (secondary sampling period) at the proposed Bear River Windpark, located in Humboldt County, California. Each night we conducted radar sampling (55 nights, ~8 h/night) and visual sampling (55 nights, ~6 h/night) at two stations (Hilltop and Mazeppa Ranch) within the proposed development area. • The primary goal of this study was to collect information on the nocturnal migration characteristics of birds and bats during spring migration. Specifically, the objectives of this study were to: (1) collect baseline information on migration characteristics (i.e., flight direction, migration passage rates, flight altitudes) of nocturnally migrating birds and bats; (2) visually estimate the relative proportions of birds and bats within the potential rotor-swept area of the proposed wind turbines; and (3) calculate an index of the number of birds and bats passing within the rotor-swept area of the proposed wind turbines during the migratory season. We also evaluated the influence of weather, sampling location, and date on migration passage rates and flight altitudes.23988:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23988Fri, 01 Oct 2010 13:29:56 -07002007-10-01T00:00:00WindEnergyWind energy biological data - On the basis of field surveys, Orloff and Flannery (1992) estimated that several hundred raptors are killed annually by turbine blade strikes, wire strikes, and electrocutions at the Altamont Pass Wind Resource Area (WRA) near Livermore, California. The most common fatalities were those of redtailed hawks (Buteo jamaicensis), American kestrels (Falco sparvarius), and golden eagles (Aquila chrysaetos), with lesser numbers of turkey vultures (Cathartes aura), common ravens (Corvus corax), barn owls (Tyto alba), and others. The numbers of discovered fatalities among certain species did not always correspond to their observed abundance in the WRA. Although Orloff and Flannery witnessed no turbine strikes, they believed that the tendency of hawks and eagles to directly pursue prey rendered them more vulnerable to collisions with structures than did the more tentative scavenging flights of turkey vultures and ravens. Among the species of raptors killed at Altamont Pass, the one whose local population is most likely to be impacted is the golden eagle. Besides its being less abundant than the others, the breeding and recruitment rates of golden eagles are naturally slow, increasing their susceptibility to population decline as a result of mortality influences. Golden eagles are a Species of Special Concern in California (California Fish and Game Department 1992), and reductions have been documented in the southern part of the state (Scott 1985, Harlow and Bloom 1987). The golden eagle is afforded special federal protection because of its inclusion within the Bald Eagle Protection Act as amended in 1963. There are no provisions within the Act that would allow the killing ("taking") of golden eagles by WRA structures. This report, in partial fulfillment of National Renewable Energy Laboratory (NREL) Subcontract XAT-6-16459-01, is the third and final of a series detailing the results and conclusions of field studies conducted in the Altamont Pass region from January 1994 to June 1997, with additional data (through December 1997) on eagle survival provided by the senior author. The primary purpose of the investigation is to estimate the extent to which turbine strikes and other hazards associated with wind energy production at Altamont Pass alter the demographic potential of the golden eagle population inhabiting the surrounding area.23987:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23987Fri, 01 Oct 2010 13:26:43 -07001999-06-01T00:00:00WindEnergyWind energy biological data - Avian mortality in Altamont Pass WRA - final report.23986:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23986Fri, 01 Oct 2010 13:19:32 -07001996-06-01T00:00:00WindEnergyWind energy biological data - The development of a l t e r n a t e energy technologies has long been a goal of the Southern California Edison (SCE). These technologies--wind, solar, and geothermal--have been planned for specific areas i n southern California. The development of these energy resources, especially wind and solar, require the use of extensive land areas. A l a r g e s c a l e wind energy development is planned for the San Gorgonio Pass and Coachella Valley areas of Riverside County (Figure 1). This development may encompass as- much as 186 km2 and could involve the i n s t a l l a t i o n of up to 32,000 wind turbine generators (WTG) (Wagstaff and Brady 1982). Along with SCE's goal to develop and d i s t r i b u t e 1 a l t e r n a t e energy resources, there is a commitment to protect the environment i n relation to each energy-related development. Therefore, t h i s envi- I ronmental concern by SCE prompted an investigation of the biological impact of wind energy development i n the San Gorgonio Pass and Coachella Valley.23985:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23985Fri, 01 Oct 2010 13:13:39 -07001984-02-01T00:00:00WindEnergyWind energy biological data - As part of Southern California Edison's (SCE) goal t o develop a l t e r n a t e and renewable energy resources, wind energy development is planned for the San Gorgonio Pass Wind Resource Area (Figure 1).

(SWE) is the proponent of a wind energy project at Bear River Ridge, Humboldt County, California. The project proposed by SWE would involve the installation and operation of approximately 25-35 two-megawatt wind turbines placed along Bear River Ridge, over a 6-mile stretch, for the purpose of generating wind power. A key element in pre-development studies for a wind energy project risk assessment involves collection of baseline information about avian and bat use in the project area. Shell Wind Energy has committed to this level of study through contracts with local experts and consultation with government agencies.23983:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23983Fri, 01 Oct 2010 13:03:51 -07002008-02-01T00:00:00WindEnergyWind energy biological data - This report presents the results of radar studies of fall nocturnal bird and bat migration conducted from 7 September–15 October 2007 at the proposed Hatchet Ridge Wind Project, located in Shasta County, California. Each night we sampled at two stations (North and Saddle) within the proposed development area. • The primary goal of this study was to collect information on the nocturnal migration characteristics of birds and bats (i.e., targets) during the peak of passerine migration during fall. Specifically, the objectives of this study were to: (1) collect baseline information on migration characteristics (i.e., flight direction, migration passage rates, flight altitudes) of nocturnally migrating targets; and (2) estimate the number of targets that would pass within the rotor-swept area of the proposed wind turbines during the migratory season. We also evaluated the influence of weather and date on migration passage rates and flight altitudes.23982:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23982Fri, 01 Oct 2010 13:00:08 -07002008-02-01T00:00:00WindEnergyWind energy biological data - The Shiloh I Wind Power Project Area is situated on roughly 6,800 acres of agricultural land in the Montezuma Hills, near Rio Vista in Solano County, California. The project consists of 100 wind turbines rated at 1.5 MW each for a total capacity of up to 150 MW. All one hundred turbines went on-line in March 2006. This report details the first year results of a three-year post-construction study of the Shiloh I wind power projects. This is the third fatality study of the newer turbine technology installed in the Collinsville Montezuma Hills Wind Resource Area (CMHWRA). These turbines are arrayed on similar landscape and habitat as that in which approximately 510 turbines of the older technology are deployed along with more than 200 turbines of the newer technology.23981:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23981Fri, 01 Oct 2010 12:56:13 -07002007-09-01T00:00:00WindEnergyWind energy biological data - This report summarizes information pulled together from several studies conducted over the last several years within the Collinsville Montezuma Hills Wind Resource Area in conjunction with a study of avian abundance and behavior patterns (November 12, 2005 through March 24, 2006) at the Shiloh II Wind Power Project in the Collinsville Montezuma Hills Wind Resource Area (CMHWRA), Solano County, California. This data was compared to data collected in the months of November through March at adjacent project areas. All of the data was examined in the context of the findings of a two year post construction survey of the High Winds Wind Farm where risk has been empirically determined. In addition a raptor nesting survey with a special focus on Golden Eagle nesting was conducted for the developer in 2005.23980:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23980Fri, 01 Oct 2010 12:51:30 -07002006-04-01T00:00:00WindEnergyWind energy biological data - Wind energy has been promoted as a low-cost, clean, and reliable option for power production in the United States and abroad (NREL 1999). However, wind energy does have environmental costs. Studies have shown that birds flying through wind resource areas can be killed by collisions with turbines (Orloff and Flannery 1992; Musters, Noordervliet, and Ter keurs 1996; Howell 1997; Hunt 1997). These studies have spurred concern over the possible negative impacts such power plants may have on avian populations. The Altamont Pass Wind Resource Area (WRA) (Figure 1), located approximately 70 km (43.5 mi) east of San Francisco, California, is 189 km2 (73 mi2) in size and contains roughly 5,000 turbines with a total capacity of 672 Megawatts. Studies of avian mortality have shown that a significant number of birds are killed within this facility, perhaps more than in any other WRA (Orloff 1992; Orloff and Flannery 1992).23979:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23979Fri, 01 Oct 2010 12:44:12 -07002002-06-01T00:00:00WindEnergyWind energy biological data - A total of 33 rounds of met tower carcass surveys have been conducted thus far in 2007. (Table 1). Six fatality incidents representing 4 different species of birds have been recorded (Table 3). Both Red-winged Blackbirds and Western Meadowlarks had the highest number of incidents with 2 each, followed by Mourning Dove and Loggerhead Shrike, each with one. One California Species of Special Concern was recorded, a Loggerhead Shrike. Eighty-three percent or five of the six incidents recorded were between 21-40 meters from the met tower, with the other incident being located between 11-20 meters (Table2).23956:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23956Wed, 29 Sep 2010 11:55:38 -07002007-09-01T00:00:00WindEnergyWind energy biological data - A radar study of Marbled Murrelets at the proposed Bear River Windpark, California prepared for Shell Wind Energy Inc.23955:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23955Wed, 29 Sep 2010 11:51:31 -07002006-11-01T00:00:00WindEnergyWind energy biological data - This report provides a preliminary (Phase I) biological assessment of potential impacts to birds and bats that might result from construction and operation of the proposed wind energy facilities on VAFB.23954:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23954Wed, 29 Sep 2010 11:45:47 -07002004-08-01T00:00:00WindEnergyWind energy biological data - Post-construction avian and bat fatality monitoring study for the high winds wind power project.

Observations of dead raptors at the Altamont Pass Wind Resource Area (WRA) (Anderson and Estep 1988, Estep 1989, and Orloff and Flannery 1992) triggered concern from regulatory agencies, environmental/conservation groups, wildlife resource agencies, and wind and electric utility industries about possible impacts to birds associated with wind energy development. Although many bird species have experienced fatalities, raptors have received the most attention (Anderson et al. 1996a, 1996b, 1997, 1999, 2000; Anderson and Estep 1988; Estep 1989; Howell 1995; Howell and Noone 1992; Hunt 1994; Johnson et al. 2000a, 2000b; Luke and Watts 1994; Martí 1994; Orloff and Flannery 1992, 1996; and Thelander and Rugge 2000, Smallwood and Thelander 2004). Emphasis on raptor fatalities probably emerged for several reasons. Low raptor population relative to many other bird groups and the symbolic and emotional value raptors hold to the American public have both contributed to an increased awareness. Businesses have legal considerations under federal and state statutes. Raptors are protected by the Federal Migratory Bird Treaty Act. Some raptors are protected by the Bald and Golden Eagle Protection Act and the Endangered Species Act.23951:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23951Wed, 29 Sep 2010 11:02:06 -07002005-08-01T00:00:00ds661Freshwater Mussels in the Middle Klamath River - 23772:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23772Tue, 14 Sep 2010 11:50:46 -07002010-05-01T00:00:00ds661Freshwater Mussels in the Klamath River of Northern California - 23771:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23771Tue, 14 Sep 2010 11:49:19 -07002010-05-01T00:00:00ds661Freshwater Mussels of the Klamath River - 23770:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23770Tue, 14 Sep 2010 11:46:32 -07002010-05-01T00:00:00ds662Freshwater Mussels of the Klamath River - 23689:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23689Tue, 14 Sep 2010 11:42:03 -07002010-05-01T00:00:00ds662Freshwater Mussels in the Middle Klamath River - 23692:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23692Tue, 14 Sep 2010 11:41:46 -07002010-05-01T00:00:00ds662Freshwater Mussels in the Klamath River of Northern California - 23693:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23693Thu, 09 Sep 2010 10:59:49 -07002010-05-01T00:00:00ds658Assessment of Conservation Status of Sensitive Freshwater Mussels in Pacific Southwest Region - 23565:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=23565Thu, 09 Sep 2010 10:13:52 -07002010-08-01T00:00:00ds323Field and Data Recording Protocols of Reptiles and Amphibians - These data are detections of reptiles in 2005 from visual encounter searches of an area constrained to a 100-m radius circle around each of 15 fixed sample points at Spears and Didion Ranches, Placer Co., CA. Surveys were done three times in April and May by trained observers searching the entire 100-m radius (3.1 ha) circular plot looking on and under rocks, logs, and debris for reptiles and amphibians. Fifty-eight detections were made of five species of reptiles and one species of amphibian.17055:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17055Fri, 22 Jan 2010 13:29:25 -08002005-01-01T00:00:00ds315Field and Data Recording Protocols of Breeding Landbirds - Birds were identified to species and counted in spring and summer in 2005 and 2006 within 100-m radius circular points in oak woodland habitat in Placer County. Different observers did the counts over the two years, and there were three and eight counts, respectively, in 2005 and 2006. The 15 points were randomly located throughout the study area. Observers were fully trained in the count methodology and bird identification, and all observers had hearing tests to ensure that they had normal hearing. Observers were rotated among sample points and individual counts. All birds seen and heard that were at least momentarily stationary on the ground, vegetation, or on the water, were were identified to species and included in the counts. Bird abundances were derived by averaging the number of individuals detected for the counts conducted in each year. Binoculars were used when necessary to identify species. The sample points were randomly selected from a 300-m by 300-m grid across the entire study area.17050:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17050Fri, 22 Jan 2010 13:29:00 -08002004-03-22T00:00:00ds316Habitat Sampling Datasheet - These data are the number individual stems of three different types of downed woody debris (DWD), which are logs and slash, from 0.05-ha circular plot habitat samples taken in 2005 at sample points at Spears and Didion Ranches, Placer County, California. There were three 0.05-ha circular habitat sampling plots at each of the 15 sample points.17052:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17052Fri, 22 Jan 2010 12:34:41 -08002004-01-01T00:00:00ds210Habitat Management and Monitoring Plan - The Crestridge Ecological Reserve is a nearly 2,400-acre Ecological Reserve as designated by the California Fish and Game Commission and a unit of the Multiple Species Conservation Program (MSCP) in San Diego County. The CDFG and MSCP both require the preparation of a habitat management and monitoring plan for the reserve that includes area-specific directives for the land and the species it supports, including species listed as "covered" under the take authorizations of the MSCP. Implementation protocols of the plan are intended to encourage the maintenance or improvement of the habitat quality of the reserve, while remaining adaptable to changing conditions on the reserve.17047:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17047Thu, 21 Jan 2010 14:08:28 -08002002-02-01T00:00:00Habitat Conservation - The goal of this draft prioritization process was to identify areas of privately-owned rangelands that have high biodiversity value and require conservation action in the next 2-10 years.15044:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=15044Thu, 21 Jan 2010 13:40:59 -08002007-08-01T00:00:00RenewableEnergyRenewable Energy - ABSTRACT: The Mohave ground squirrel (Spermophilus mohavensis) is found only in the western Mojave Desert of California. Although it is listed as Threatened by the State of California, there is little published information regarding its current distribution and status. I have assembled a comprehensive database covering unpublished field studies, surveys, and incidental observations conducted over the 10-year period from 1998-2007. This database contains records of 1140 trapping sessions, only 102 of which were successful in capturing >1 Mohave ground squirrels. In addition, there are 96 incidental observations in which the species was detected. An analysis of these 198 positive records identifies 4 core areas that continue to support relatively abundant Mohave ground squirrel populations and 4 other areas in which there are multiple recent records of the species. Although the southern portion of the range has been most intensively sampled, the only recent occurrences there are from a single core population on Edwards Air Force Base plus an additional 4 detections from Victor Valley. There are extensive areas within the geographic range where the status of the species is unknown, especially on the China Lake Naval Air Weapons Station and Fort Irwin. I present recommendations for surveys in areas where no recent studies have been carried out. I also identify potential corridors between known populations and recommend studies to determine if these connections are actually occupied by the species. Finally, I indicate conservation measures needed to ensure that known populations and corridors are adequately protected from habitat loss and degradation.15148:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=15148Thu, 21 Jan 2010 13:37:43 -08002008-01-01T00:00:00ds121Sensitive Plant Monitoring - The County of San Diego owns or is in the process of acquiring key lands within the Multiple Species Conservation Program (MSCP) preserve area. The MSCP Biological Monitoring Plan requires monitoring of covered plant species. The County of San Diego was awarded two Natural Communities Conservation Planning (NCCP) Program Local Assistance Grants to accomplish the first phase of the monitoring program, i.e., collecting baseline data for covered plant species. The study area of this grant was amended to include lands in San Vicente (Boys and Girl’s Club) Ecological Reserve that were originally included in the statement of work for the NCCP Local Assistance grant No. P0050008. The lands in the total amended study area, from north to south are open space areas in Santa Fe Valley, County-owned portions of Lusardi Creek, open space areas conveyed to the County of San Diego in 4S Ranch, San Vicente Open Space Preserve, McGinty Mountain preserve lands, Hollenbeck Canyon Wildlife Area, and lands north and south of the eastern arm of Otay Lakes. Portions of Rancho Jamul Ecological Reserve were also surveyed. 2825:10https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=2825Thu, 21 Jan 2010 13:37:34 -08002005-01-01T00:00:00ds169Plant Classification and Mapping - 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 comminutes using 1:24,000 true color photos.17023:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17023Thu, 21 Jan 2010 13:37:13 -08002003-07-30T00:00:00ds170Vegetation Classification and Mapping - 17024:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17024Thu, 21 Jan 2010 13:37:05 -08002005-01-01T00:00:00ds188Vernal Pool - Vernal pools are seasonal, depression-type wetlands that result from a unique set of physical parameters and support a specific biological assemblage. These ecosystems have been greatly reduced due to development and other anthropogenic factors, and several plants and animals endemic to vernal pools have been listed as federal and/or state endangered species.17029:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17029Thu, 21 Jan 2010 13:36:20 -08002002-01-01T00:00:00ds211Biological Resource Mapping - In order to standardize the vegetation mapping and monitoring effort, Oberbauer modified the vegetation classification system for San Diego County based on the work of Holland. These classifications were used in the vegetation mapping of the Crestridge Ecological Reserve in 2000. Changes in the extent of vegetation types should be monitored periodically to assess the vegetation health and condition, and the general level of disturbance in the Reserve. 17048:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17048Thu, 21 Jan 2010 13:35:22 -08001996-01-01T00:00:00ds324Resource Assessment Program's Coverboard Study - The data are detections of reptiles in 2006 under 2 ft x 2 ft plywood coverboards at four of 15 sample points at Spears and Didion Ranches, Placer County, CA. There are 81 coverboards in a 9 board by 9 board array (on 15 m spacing) centered on the sample points. Coverboards were placed in oak woodland and annual grassland habitat in Nov.-Dec. 2005 and checked bi-weekly between Mar.-Jul. 2006. All 204 animals found under the coverboards were counted, identified to species, and aged and sexed.17064:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17064Thu, 21 Jan 2010 13:33:47 -08002000-01-01T00:00:00
