California Department of Fish and Wildlife (formerly California Department of Fish and Game) 201412 http://www.dfg.ca.gov/biogeodata/cwhr/ 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 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. California Wildlife Habitat Relationships (CWHR) is a state-of-the-art information system for California's wildlife. CWHR contains life history, geographic range, habitat relationships, and management information on 694 species of amphibians, reptiles, birds, and mammals known to occur in the state. CWHR products are available to anyone interested in understanding, conserving, and managing California's wildlife. Range maps 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. -124.5 -114.0 42.0 32.5 None wildlife habitat natural resources species amphibians reptiles birds mammals biota environment None None California Department of Fish and Wildlife FGDC Content Standard for Digital Geospatial Metadata FGDC-STD-001-1998 local time
