Range maps of California's regularly-occurring vertebrates were digitized as GIS layers to support the predictions of the CWHR System software, which allows users to query for wildlife species meeting a set of location and habitat conditions. Presently, they are used to help generate a tabular location database for the system software. Outside the system software, the GIS layers are used to support species richness assessments for statewide conservation planning.
Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), 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 wildlife species known to occur regularly in California. 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. For more information about CWHR, visit the CWHR webpage ( https://www.wildlife.ca.gov/Data/CWHR ). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.
