  1. Title: Vernal Pool Complexes: San Francisco Bay Area, California, 1998

    Contributors:

    Summary: This polygon shapefile depicts existing vernal pool complexes, not individual vernal pools, in the nine county San Francisco Bay Area Region, California as identified and mapped by Dr. Robert F. Holland. The purpose of the inventory was to map the distribution of vernal pool complexes for use by the United States Fish and Wildlife Service in recovery planning for listed and sensitive species. True color aerial slides from the Department of Water Resources were interpreted and vernal pool complexes were identified. Complexes more than 40 acres in size were then digitized as polygons and given a density rating. Since the minimum mapping unit of the coverage is 40 acres, it may not provide the level of detail required for larger scale (smaller area, more site-specific) conservation planning. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships. The Conservation Lands Network GIS Database is the primary output of the Project. The data depicts the spatially explicit CLN that is recommended for the nine county San Francisco Bay Area Region, California.

SUMMARY 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. In 1995, Dr. Robert F. Holland identified the complexes on aerial photos (the most recent available for each county) and traced the polygons onto USGS 7.5' quads from which they were digitized. Vernal pool complexes were then given a density rating. The coverage was refined in June of 1998, with SPOT Imagery and recent U2 (low-flying aircraft) photography. The layer does not contain delineations of individual vernal pools and was not intended for use in wetland delineations. FULL METADATA (DRAFT) COVERAGE NAME: usfwsvp2 COVERAGE DATE: June 22nd, 1998 METADATA FILE: vpool_meta.txt METADATA DATE: August, 1998 COVERAGE DESCRIPTION: The VERNAL POOLS coverage (USFWSVP) is a polygon coverage representing existing vernal pool complexes in California's Central Valley, as identified and mapped by Dr. Robert F. Holland. The purpose of the inventory was to map the distribution of extant CA Central Valley vernal pool complexes for use by the U.S. Fish and Wildlife Service in recovery planning for listed and sensitive species. True color aerial slides from the Dept of Water Resources were interpreted, and vernal pool complexes were identified. Complexes more than 40 acres in size were then digitized as polygons and given a density rating (described below). This coverage was created to help biologists and resource planners make informed decisions in their recovery and planning efforts. It depicts vernal pool complexes, not individual vernal pools. Since the minimum mapping unit of the coverage is 40 acres, it may not provide the level of detail required for larger scale (smaller area, more site-specific) conservation planning. The coverage was created using the Arc/Info command `CREATE', using an existing coverage as a template for cartographic parameters. After the initial setup of the coverage for data input, vernal pool polygon complexes were digitized into the G.I.S database. The coverage was then built, the tolerances set and the attribute fields added. The polygon boundaries were refined by Dr. Holland by reviewing U2 (low-flying aircraft) photographs and 1:130,000 scale paper plots of the original data laid over SPOT Imagery. The changes were then edited in the G.I.S. database. VITAL STATISTICS: Datum: NAD 27 Projection: Albers Units: Meters 1st Std. Parallel: 34 00 00 (34.0 degrees N) 2nd Std.

Description of items (fields): QUADNAME: Name of USGS quadrangle (24K) where data were originally digitized from. LUCODEOLD: There are nine fields, marked 1-9. Cut_Out = 0 Density Index = 1 Density Index = 2 Density Index = 3 Cultivated = 4 Developed = 5 Mitigated Site = 6 Extirpated = 7 Disturbed DI 1 = 8 (disturbed vernal pool/density index of 1) Disturbed DI 2 = 9 (disturbed vernal pool/density index of 2) Density Indexes Described 0 = CUT_OUT. These polygons are 'do-nut' holes within vernal pool complexes; e.g. a cultivated feld surrounded by habitat. 1 = LOW DENSITY. Pools are small, widely and patchily scattered. At least 2 pools and usually 5 or more exist within the delineated complex. 2 = MEDIUM DENSITY. Pools are larger, more numerous, and more pervasively scattered, but still patchy within the delineated complex. 3 = HIGH DENSITY. Pools are all sizes and numerous. Pools are distributed over the entire delineated vernal pool complex. Also includes large, isolated playa-like pools. 4 = CULTIVATED. Pools are present and persist in spite of obvious cultivation, usually of hay crops. 5 = DEVELOPED. Pools are present and still visible in spite of subdivision into parcels smaller than minimum mapping size. 6 = MITIGATED SITE. The site is a mitigated area consisting within a vernal pool complex. (Not used in this project) 7 =EXTIRPATED. Pools were present in earlier photos, but were gone in 1997 U2 flight photos.. 8 = DISTURBED DI 1. This is a polygon/delineated complex that is fits the criteria of 'density index of 1', but that is disturbed in some way or form. 9 = DISTURBED DI 2. This is a polygon/delineated complex that is fits the criteria of 'density index of 2', but that is disturbed in some way or form. DATEOLD: This is the year of the photographs used for each county in the original 1995 aerial photo interpretation. COUNTY: This is the county in which the polygon is contained. LUCODENEW: These are 1997-1998 updates of LUCODEOLD, especially where land use changes have taken place. DATENEW: This is the year the check was done with SPOT Imagery and U2 photography. DATA QUALITY ASSESSMENT This coverage depicts vernal pool complexes, not individual vernal pools. The density ratings are subjective but were validated with actual point occurrence data of individual vernal pools. (For a copy of the paper "A Comparison of Two Methods for Mapping Vernal Pools" contact Monica Parisi, Wildlife Biologist at (916) 657-4341 or e-mail The validation suggested that 1.) dense complexes of vernal pools were being picked up by aerial photo interpretation and 2.) the density ratings should not be the sole basis for identifying high priority preserve areas, especially at the local planning level. At the local level, this layer is probably best used for suggesting new areas for regional preserves, areas which may never have been considered because of a lack of information.

  2. Title: Vernal Pools: South Coast Ranges, California, 1998

    Contributors:

    Summary: This polygon shapefile depicts vernal pools in Monterey, Santa Barbara, San Benito, San Luis Obispo and Ventura counties that were mapped from one-meter resolution digital orthophoto quadrangles (DOQQs) from the United States Geological Survey, mostly based on 1994 air photos. Mapping from DOQQs subsequently was checked against 10-meter resolution SPOT cover taken during the summer of 2000. This coverage presents findings from comprehensive mapping of vernal pool habitats in Monterey, Santa Barbara, San Benito, San Luis Obispo and Ventura counties. In 1995, Dr. Robert F. Holland identified the complexes on aerial photos (the most recent available for each county) and traced the polygons onto USGS 7.5' quads from which they were digitized. Vernal pool complexes were then given a density rating. The coverage was refined in June of 1998, with SPOT Imagery and recent U2 (low-flying aircraft) photography. The layer does not contain delineations of individual vernal pools and was not intended for use in wetland delineations.

  4. Title: Vernal Pools Study Area: Central Valley, California, 1998

    Contributors:

    Summary: This polygon shapefile is believed to represent a boundary used for mapping vernal pool complexes in a study by Dr. Robert F. Holland (reference the mapped vernal pool complexes dataset named "usfwsvp2" for related information).True color aerial slides from the Deptartment of Water Resources were interpreted, and vernal pool complexes were identified. Complexes more than 40 acres in size were then digitized as polygons and given a density rating (see Resource Fields for attribute definitions). This layer was created to help biologists and resource planners make informed decisions in their recovery and planning efforts. It depicts vernal pool complexes, not individual vernal pools. Since the minimum mapping unit of the coverage is 40 acres, it may not provide the level of detail required for larger scale (smaller area, more site-specific) conservation planning.
