The original source of this polygon coverage, titled 'usfwsvp2', is the U.S. Fish and Wildlife Service and California Department of Fish and Game's Holland's Central Valley Vernal Pools Coverage datafiles. Rr_usfwsvp2.shp was created by Circuit Rider Productions, Inc. Rr_usfwsvp2 represents the portion of the Holland's Central Valley Vernal Pools Coverage polygon coverage that is within the watershed boundaries of the Russian River basin. This metadata file incorporates information that is specific to this layer as well as information that is available in the original metadata file for the 'Holland's Central Valley Vernal Pools Coverage' layer. Portions of this metadata file that borrow text from Holland's Central Valley Vernal Pool Coverage are indicated in quotation marks.

Description:

Abstract: "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."

 

Purpose: "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."

"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."
