California Department of Fish and Wildlife 20080101 vector digital data http://bios.wildlife.ca.gov ftp://ftp.wildlife.ca.gov/BDB/GIS/BIOS/Public_Datasets/500_599/ds524.zip This data set is an intersection of 694 vector polygon ranges in the California Wildlife Habitat Relationships (CWHR) System with a statewide grid of 25 square mile hexagon cells. The shapefile contains the hexagon cells and their i.d. numbers (HEX25_ID). The polygon range GIS layers used for the intersection were the same layers as those that appeared in Version 8.2 of the CWHR System software. Both the ranges and the system software have since been updated and are available for download from our CWHR web page at https://www.wildlife.ca.gov/Data/CWHRThe hexagon analysis is being rerun with the newly updated ranges and will replace the currently available hexagon layers as soon as they are complete. The individual range layers are also available through our BIOS Map Viewer https://www.wildlife.ca.gov/Data/BIOS The intersection of the range maps with fine-scale hexagon cells allows for a rapid query of any portion of the state for the presence of a number of species. The resulting table lists the common and scientific names of all species within a taxonomic group whose ranges intersect the selected area. Vector datasets representing species' ranges are one component of 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. Due to the size of this dataset the attributes were separated into two tables based on Common Name. See CWHR_Birds_(Le-Y) [ds527] for the second part of this dataset. 20080101 publication date Complete As needed -125.489710 -113.356496 42.189156 32.262229 None wildlife habitat birds species ISO 19115 Topic Category biota environment None California None None California Department of Fish and Wildlife, Biogeographic Data Branch Melanie Gogol-Prokurat mailing

SCI_NAME The scientific name of the species, subspecies or population. CWHR_ID The data is organized into four major taxonomic groups in CWHR: amphibians, reptiles, birds and mammals. Each species is represented by its 4 digit alpha-numeric CWHR ID code. SEASON Season codes indicating time of year: 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". PCT_AREA The percentage of each individual hex polygon that is overlapped by the specified species range layer. 20160913 California Department of Fish and Wildlife GIS Service Center geodata@wildlife.ca.gov FGDC Content Standard for Digital Geospatial Metadata FGDC-STD-001-1998 local time
