Summary: This polygon shapefile depicts a watershed integrity cluster analysis at the CalWater 2.2.1 Planning Watershed (PWS) level performed by mapping factors representing some of the most significant watershed threats. Each of the individual watershed integrity factors was individually mapped and then combined in the watershed cluster analysis. This individual threat, cultivated, was created by taking CalWater watersheds at the planning unit level (most refined) and running zonal stats, part of spatial analyst. The Calwater PWS watershed was the zone dataset (pwsname as the zone field) and Population Density as the value raster. The result gives you the mean percent population density of the nine county San Francisco Bay Area Region, California at the watershed level in a table that you can join back to the CalWater GIS layer and then symbolize as a graduated color with the mean being the value field. This analysis was done by the Conservation Lands Network Fish and Riparian Focus Team. 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.

Summary: This polygon shapefile depicts a watershed integrity cluster analysis at the CalWater 2.2.1 Planning Watershed (PWS) level performed by mapping factors representing some of the most significant watershed threats. Each of the individual watershed integrity factors was individually mapped and then combined in the watershed cluster analysis. This individual threat, cultivated, was created by taking calwater watersheds at the planning unit level (most refined) and running zonal stats, part of spatial analyst. The Bay Area Open Space Council Bay Area Protected Areas Database (BPAD) protected areas data was converted to a grid so that zonal stats could be used. The CalWater PWS watershed was the zone dataset (pwsname as the zone field) and BPAD Protected as the value raster. The result gives you the mean percent protected in the nine county San Francisco Bay Area Region, California at the watershed level in a table that you can join back to the CalWater GIS layer and then symbolize as a graduated color with the mean being the value field.

Title: Fire Rotation: San Francisco Bay Area, California, 2004
Contributors:- Raster data

- GreenInfo Network (Firm)
Summary: This raster dataset depicts fire rotation class intervals calculated from 1950-2003 fire history on land areas grouped into strata based on fire environment conditions for the nine county San Francisco Bay Area Region, California. These strata are defined by vegetation, climate, direct protection agency and elevation. The fire rotation interval is the expected number of years it would take, based on past fire rates, to burn an area equivalent to that of a given stratum. Fire rotation interval for a given stratum is calculated by dividing the mean annual number of acres burned into the total area of the stratum. Finally, fire rotation values are grouped into classes. The larger fire rotation values correspond to less frequent burning. In contrast the higher the rotation class value is, the more frequent fire is in that stratum. The source data was compiled by the California Department of Forestry and Fire Protection and the United States Department of Agriculture Forest Service. 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.

Title: Shrew Mole Range (Reverse Polygon Mask): San Francisco Bay Area, California, 2008

- GreenInfo Network (Firm)
Summary: This polygon shapefile depicts the range map the American shrew mole (Neurotrichus gibbsii) that were pulled out and then reversed so the polygon represents areas outside of their range. This creates a mask so the actual species ranges can be shown while the area outside of its range can be masked out. Vector datasets are a component of the California Wildlife Habitat Relationships (CWHR) range maps, a comprehensive information system and predictive model for California's wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution and habitat relationships for 694 species of amphibians, reptiles, birds and mammals known to occur regularly in the state. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. 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.

Shrew Mole Range (Reverse Polygon Mask): San Francisco Bay Area, California, 2008. Bay Area Open Space Council. Available at http://purl.stanford.edu/rz419vp0242. The following information describes, and should always accompany, the California Department of Fish and Game's California Wildlife Habitat Relationship System (CWHR) species distribution data. The data is organized into four folders according to the four major taxonomic groups in CWHR: amphibians, reptiles, birds and mammals. Each species is represented by a single shapefile and is named according to its 4 digit alpha-numeric CWHR ID code. The file lookup.xls contains a record for each species including its CWHR ID, scientific name, common name, and range map revision history. Each layer contains two attributes: a season code and a SHAPE_NAME or CWHR ID code. Season codes include S for summer-only, W for winter-only, and Y for yearlong. A few species have a migration-only stopover location mapped and represented with an "M". The CWHR System software contains species predictions for migration-only locations, yet most of these are not mapped. The CWHR species range maps are continually being reviewed and updated as new animal occurrence data becomes available, especially in digital format. While the original maps were digitized from 1:5,000,000 scale depictions of range, a major revision effort started in 1995 to have maps reviewed and delineated by species-level experts at a scale of 1:1,000,000. Maps dated later than 1995 are therefore much more detailed and precise in their representation of a species' range. Increasingly, species-level experts and CWHR staff have made every effort, where justified by the distribution of known species observations or known habitat associations, to represent a species' range with standard polygons of major geographic features in California such as mountain ranges, valleys, buffered river corridors, and ecological subsections of California. The smallest units of the "Ecological subregions of California: section and subsection descriptions" (Miles and Goudy, 1997. USDA Forest Service Report No. R5-EM-TP-005) capture areas with very similar soils, vegetation, precipitation, geology, climate, and geography. In cases where a population of a species is known to be isolated, its point location is buffered to a minimum radius of 2 miles.

Title: Rural Lands: San Francisco Bay Area, California, 2008
Contributors:- Polygon data

- GreenInfo Network (Firm)
Summary: This polygon shapefile depicts rural lands in the nine county San Francisco Bay Area Region, California. This data was derived from the California Department of Conservation Farmland Mapping and Monitoring Program (FMMP) data. This dataset was developed to get a better regional understanding of the exurban sprawl issues in regions lying just beyond the suburbs of a city. The Conservation Lands Network (CLN) Project Team felt that parcels under ten acres generally resulted in more fragmented landscapes where conservation action is more challenging and biodiversity tends to be much lower. The dataset was developed by: 1) selecting out all parcels ten acres or less for each county; 2) eraising FMMP Urban Areas and Intensive Cultivated Land; 3) converting to a grid; 4) merging with a grid of the entire region to get 1,0 for null areas; and 5) running nearest neighbor statistcs type majority filter, rectangle neighbor, settings of 5, using the 1,0 field (this helps to fill in the road network and get rid of the streets in the congested areas). This data was integrated into the CLN Vegetation map as a new category for purposes of reducing the conservation goals in these areas. 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.

- GreenInfo Network (Firm)
Summary: This polygon shapefile depicts a dissolve that was run on the Hydrologic Sub Areas for the nine county San Francisco Bay Area Region, California. Hydrologic Sub Areas are those ranging in size from 195-243 square miles or 125,000-155,999 acres (Myers & Peltz-Lewis, 2004). This data was derived from the California Watershed Map (CalWater version 2.2), a set of standardized watershed boundaries meeting standardized delineation criteria. The hierarchy of watershed designations consists of six levels of increasing specificity: Hydrologic Region (HR), Hydrologic Unit (HU), Hydrologic Area (HA), Hydrologic Sub Area (HSA), Super Planning Watershed (SPWS) and Planning Watershed (PWS). The primary purpose of CalWater is the assignment of a single, unique code to a specific watershed polygon. Watersheds are useful for many aspects of the Project, including development of watershed integrity analysis. These data were critical for the Fish and Riparian Focus Team portion of the Project. 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.
