Vernal Pool Complexes - Central Valley - 1989-1998 [ds36]

This Arc/Info coverage is a polygon layer of vernal pool complexes greater than 40 acres in size for 29 counties throughout the greater Central Valley, and some north bay counties. These data were collected and vernal pool complexes were identified and mapped by Dr. Robert F. Holland in 1995 and refined in a 1998 update. This layer does not contain delineations of individual vernal pools and is not intended for use for wetland delineations or regulatory use. For additional information on the vernal pools mapping projects see the report, Changes in Great Valley Vernal Pool Distribution from 1989 to 1997, June 1998, by Robert F. Holland, Ph.D. It is available online at: http://www.dfg.ca.gov/bdb/wetlands/vp_holland/report_index.htm .

Vegetation - Central Sierra Hardwoods [ds41]

These data represents the results of vegetation plots in west-slope Sierra Nevada forests. There is accompanying point count surveys for birds (see Central Sierra Hardwood Study - Birds) made at these survey plots. Please be aware that the coordinates of the points displayed in the text data display of this data set are California Teale-Albers NAD27 projection, but that the data point viewer displays these data points and the background layers in California Teale-Albers NAD83 projection. TIME PERIOD COVERED. These data were collected during 2002 and 2003 between June-August by field crews working for California Department of Fish and Game. GEOGRAPHIC EXTENT OF THE RECORDS. Vegetation plots extend from El Dorado to Tuolumne counties in the central Sierra Nevada between 2000-6000 ft elevation. NUMBER OF RECORDS. There are 64 stands with habitat attributes measured from 3-4 0.2-acre sampling plots per stand. BASE DATA STRUCTURE. The file is a flat table which gives vegetation attributes for each stand. Each stand is represented by two key fields called "Quad" and "Grid" which relate these habitat records to bird survey data collected in 2003 from the same sample stands. WHAT EACH RECORD REPRESENTS. Each record in the table represents the stand's site attributes, habitat attributes, and California Wildlife Habitat (CWHR) classification type. Average values for each stand represent the grand mean of average values from the 3-4 plots measured at each sample stand or the average of single measurements of attributes from the 3-4 plots measured at each sample stand.
Vegetation - Sierra Nevada Foothills [ds83]

TIME PERIOD COVERED These data were collected between May-July 2004 by field crews working for California Department of Fish and Game. GEOGRAPHIC EXTENT OF THE RECORDS Vegetation plots occur in two study areas on public lands in Yuba and Tehama Counties in the Sierra Nevada foothills. NUMBER OF RECORDS There are 183 records with habitat attributes measured from 0.05 - 0.10 hectare sampling plots. BASE DATA STRUCTURE The file is a flat Excel table which gives vegetation attributes for each habitat plot. Each habitat plot is represented by two key fields called "SAMPLE_ID" and "PLOT_NUM" which relate these habitat records to bird and herpetile survey data collected in the same year from the same sample points. WHAT EACH RECORD REPRESENTS Each record in the table represents the average values for habitat attributes from plots that can be linked with bird count data from the same points. Average values for each sample represent the mean of average values from 3 habitat plots measured at each point.
Aspen Stands - Warner Mountain [ds112]

This dataset displays aspen stands in the Warner Mountains south of State Highway 299. The 1946 and 1994 data are presented as polygons depicting aspen stands derived from aerial photos taken in 1946 and 1994, respectively, while the 2002 data includes the aspen stand delineations and their corresponding vegetation data (i.e., size distribution of aspen, the canopy and shrub cover, the number of species of grasses and forbs, and the ratio of conifers to aspens). The polygons ranged in size from less than 0.2 acres to more than 1,130 acres. There are 2103 records, one for each aspen stand mapped and sampled. All data were collected and summarized by Aaron Di Orio, California Department of Fish and Wildlife. This is one of three data sets for a study investigating change in the size of aspen stands since 1946. Other available data sets are 1946 and 1994 aerial photo mosaics.
Vegetation - Suisun Marsh - 2000 [ds161]

This vegetation mapping project of Suisun Marsh 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 locally or statewide ( http://www.nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24570 ).
Vegetation - Suisun Marsh - 2003 [ds162]

Vegetation - Anza-Borrego Desert State Park [ds165]

The Anza Borrego Desert State Park (ABDSP) Vegetation Map depicts vegetation within the Park and its surrounding environment. The map was prepared by the Department of Fish and Game (DFG) under contract to the Department of Parks and Recreation (DPR) to assist DPR with preparation of a General Plan for ABDSP. The vegetation map was prepared using aerial photographs, field investigation, vegetation classification, and GIS processing and provides information on the location and extent of 94 vegetation types in the project area. The primary vegetation classification used for the project is based on A Manual of California Vegetation (Sawyer and Keeler-Wolf 1995). The data and classification work arising from this project will be used to refine future editions of the Manual. The vegetation map references other vegetation classifications as well.
Vegetation - Central Mojave Desert [ds166]

The Department of Defense and the other desert managers are developing and organizing scientific information needed to better manage the natural resources of the Mojave Desert. One product from this endeavor is the Central Mojave Vegetation Map (developed by US Dept of Interior, USGS Western Ecological Research Center and Southwest Biological Science Center) that displays vegetation and other land cover types in the eastern Mojave of California. Map labels represent alliances and groups of alliances as described by the U.S. National Vegetation Classification. The nominal minimum mapping unit is 5 hectares. Each map unit is labeled by a primary land cover type and a secondary type where applicable. In addition, the source of data for labeling each map unit is also identified in the attribute table for each map unit. Data were developed using field visits, 1:32,000 aerial photography, SPOT satellite imagery, and predictive modeling.
Vegetation - San Felipe Valley Wildlife Area [ds172]

This Vegetation Map of the San Felipe Valley Wildlife Area in San Diego County, California is based on vegetation samples collected in the field in 2002 and 2005 and on photo interpretation of a 2000 Color Infrared (CIR) Image. The map legend is based on classification of the plots and follows the hierarchical National Vegetation Classification System (USGS-NPS 2005) and Manual of California (Sawyer and Keeler-Wolf 1995). Types are cross-walked to California Wildlife Habitat Relationships (CWHR) and Holland types. No report was produced; this metadata serves to document the entire project. WHAT EACH RECORD REPRESENTS: Each record represents the attributes of the individual polygon in the map layer, including vegetation type, structural information, and disturbance information. The map represents vegetation as it existing prior to the 2002 Pines Fire. Polygons are attributed to the lowest level of the classification hierarchy allowed by the image resolution and comfort level of the photo interpreter. Thus, individual polygons are mapped to the Formation, Alliance or Association level. Several "mapping units" not in the vegetation classification were also used in the mapping classification (=map legend). The hierarchical classification and crosswalk allow mapping at coarser levels or in different systems (e.g., CWHR). If mapping at the Formation level (the "1000s" in the spreadsheet), please consider including the California juniper types 2106, 2171, 2172 and 2173 in the 4000s (Evergreen Shrubland). This juniper is considered a tree in the national classification, but is more shrub-like and its desert affinities make California juniper types fit more logically into the Evergreen Shrubland Formation.
Coho Abundance - Point Features [ds182]

The CalFish Abundance Database contains a comprehensive collection of anadromous fisheries abundance information. Beginning in 1998, the Pacific States Marine Fisheries Commission, the California Department of Fish and Game, and the National Marine Fisheries Service, began a cooperative project aimed at collecting, archiving, and entering into standardized electronic formats, the wealth of information generated by fisheries resource management agencies and tribes throughout California. Extensive data are currently available for chinook, coho, and steelhead. Major data categories include adult abundance population estimates, actual fish and/or carcass counts, counts of fish collected at dams, weirs, or traps, and redd counts. Harvest data has also been compiled for many streams. This CalFish Abundance Database shapefile was generated from fully routed 1:100,000 hydrography. In a few cases streams had to be added to the hydrography dataset in order to provide a means to create shapefiles to represent abundance data associated with them. Streams added were digitized at no more than 1:24,000 scale based on stream line images portrayed in 1:24,000 Digital Raster Graphics (DRG). These features represent abundance information resulting from counts at weirs, fish ladders, or other point-type monitoring protocols such as beach seining. The point features in this layer typically represent the location for which abundance data records apply. In many cases there are multiple datasets associated with the same point location, and so, point features overlap. Please view the associated datasets for detail regarding specific features. In CalFish these are accessed through the "link" field that is visible when performing an identify or query operation. A URL string is provided with each feature in the downloadable data which can also be used to access the underlying datasets. The coho data that is available via the CalFish website is actually linked directly to the StreamNet website where the database's tabular data is currently stored. Additional information about StreamNet may be downloaded at [http://www.streamnet.org]. Complete documentation for the StreamNet database may be accessed at [http://http://www.streamnet.org/def.html]

Major data categories include adult abundance population estimates, actual fish and/or carcass counts, counts of fish collected at dams, weirs, or traps, and redd counts. Harvest data has been compiled for many streams, and hatchery return data has been compiled for the states mitigation facilities. A draft format has been developed for juvenile abundance and awaits final approval. This CalFish Abundance Database shapefile was generated from fully routed 1:100,000 hydrography. In a few cases streams had to be added to the hydrography dataset in order to provide a means to create shapefiles to represent abundance data associated with them. Streams added were digitized at no more than 1:24,000 scale based on stream line images portrayed in 1:24,000 Digital Raster Graphics (DRG). These features generally represent abundance counts resulting from stream surveys. The linear features in this layer typically represent the location for which abundance data records apply. This would be the reach or length of stream surveyed, or the stream sections for which a given population estimate applies. In some cases the actual stream section surveyed was not specified and linear features represent the entire stream. In many cases there are multiple datasets associated with the same length of stream, and so, linear features overlap. Please view the associated datasets for detail regarding specific features.
