  1. Title: Districts: California Department of Fish and Wildlife, 2008

    Contributors:

    Summary: This polygon shapefile depicts boundaries of the California Department of Fish and Wildlife Districts. Various data sources were used to represent the boundaries. Overall, the boundaries are largely based on 100K source data (such as county boundaries). This coverage provides for general display and analysis of the California Department of Fish and Wildlife Fish and Game Districts, created for the protection of fish and game as described in the California Fish and Game Code, Division 8, Section 11000. California Department of Fish and Wildlife Marine Resources Region. (2008). Districts: California Department of Fish and Wildlife, 2008. California Department of Fish and Wildlife. Marine Resources Region. Available at: http://purl.stanford.edu/vs537rq7663. This layer is presented in the WGS84 coordinate system for web display purposes.

  2. Title: California Coastal Surf Grass, 2005

    Contributors:

    Summary: This polyline shapefile depicts distribution of surf grass along the California Coast. This data was extracted from a larger set of data which contained plant species found along the coast derived from the Minerals Management Service (MMS) maps data for the Pacific Coast intertidal shorelines of the Monterey Bay, Gulf of the Farallones and Channel Islands National Marine Sanctuaries.This data describes shoreline habitat characteristics and biological assemblages on United States Geologic Survey (USGS) quad maps.

  3. Title: Lakes, Reservoirs and Ponds (Polygons): California, 2012

    Contributors:

    Summary: This polygon shapefile is an update of California lake, reservoir, and pond layers as assembled by the California Department of Fish and Game (DFG). It includes many small and unnamed waterbodies in the High Sierra and California Cascades, some of which are not depicted on United States Geological Survey 7.5 arc-minute/1:24,000-scale topographic maps. Most data were captured at 1:24,000-scale or better. Waterbodies are represented as single polygons (with islands), with Latitude/Longitude coordinates of waterbody centroids and a unique numeric identifier for each. Waterbody polygons represent shorelines generally at full or near-full levels. A previous version of this dataset did not contain islands. The dataset was created for two purposes: First, to attempt to correct many inaccuracies in current GIS datasets for California waterbodies, especially regarding NAMES. Second, to provide a unique numeric ID system for the California Department of Fish and Wildlife of all digitized waterbodies in California in order to assist with fisheries and biological programs management and public fishing programs, including biological surveys, fish planting, and public fishing guides. California Department of Fish and Wildlife, 2012. Rancho Cordova CA: North Central Region (Region 2); Sacramento CA: Biogeographic Data Branch. This dataset represents a combination of 1:24,000-scale or better GIS datasets considered the best currently available. The initial sources come from DFG's fisheries programs, some of which included many Sierra Nevada lakes and ponds not represented on existing USGS maps and/or not known to exist in digitized format elsewhere. Unique ID's in the field DFGLAKEID reflect the LAKE_ID in FPB_Lakes shapefile in about 22,400 cases. Many errors (attribute and spatial) existed in all the contributing datasets, and many (but not all) have been remedied here. Lake name errors were addressed to the greatest extent, spatial representation errors to a lesser extent. USGS National Hydrography Dataset (NHD) High Resolution 'waterbody' polygons were used to replace some existing polygons. It was not used exclusively however, due in part to existing errors within the NHD datasets to date, the lack of completeness for CA and the lack of time on the editors end to incorporate NHD in cases where NHD polygon representation is better than what exists here. It is the intent that NHD polygons will be incorporated more as they get updated. This layer is presented in the WGS84 coordinate system for web display purposes.

  4. Title: Lake, Reserviors and Ponds (Points): California, 2012

    Contributors:

    Summary: This point shapefile is an update of California lake, reservoir, and pond layers as assembled by the California Department of Fish and Game (DFG). It includes many small and unnamed waterbodies in the High Sierra and California Cascades, some of which are not depicted on United States Geological Survey 7.5 arc-minute/1:24,000-scale topographic maps. Most data were captured at 1:24,000-scale or better. Waterbodies are represented as centroid points. The dataset was created for two purposes: First, to attempt to correct many inaccuracies in current GIS datasets for California waterbodies, especially regarding NAMES. Second, to provide a unique numeric ID system for the California Department of Fish and Wildlife of all digitized waterbodies in California in order to assist with fisheries and biological programs management and public fishing programs, including biological surveys, fish planting, and public fishing guides. This coverage provides an accompanying center point GIS layer for the lakes layer that was assembled by the California Department of Fish and Game. This point layer is useful for representing lake locations at small (zoomed-out) scales, labeling, etc. California Department of Fish and Game: North Central Region (Region 2) and the Biogeographic Data Branch. (2012). Lake, Reserviors and Ponds (Points): California, 2012. Available at: http://purl.stanford.edu/pt381mp4669. Points derived from fields containing coordinate values within the lakes dataset. Those values were derived from initially gaining 'centroids' using ArcGIS command tools, then editing the points as needed to place in a more central location within the lake polygons.

  19. Title: Important Bird Areas: San Francisco Bay Area, 2008

    Contributors:

    Summary: The objective of this project was to digitally map the boundaries of Audubon California's Important Bird Areas (IBA). Existing Important Bird Areas identify critical terrestrial and inland water habitats for avifauna, in particular, habitat that supports rare, threatened or endangered birds and/or exceptionally large congregations of shorebirds and/or waterfowl. The digitization of Important Bird Areas represents an important first step in conservation planning of these critical habitats using GIS. As of October 2007, a draft layer of all 148 Important Bird Areas in California was completed. Currently, a review is in progress with Audubon Chapters and local experts, with a final version completed by Nov. 1, 2008. The final map and data will be released to the public in November, 2008.
