This dataset was created as published December 8, 2020, as an aid to CDFW, the State Water Resources Control Board, and the public following the enactment of Senate Bill 637 in 2015. (Stats. 2015, ch. 680, 1-4.) The dataset is a representation of the Class A year-round and Class B through H seasonal restrictions set forth in section 228.5 of Title 14 of the California Code of Regulations. This regulation governs the use of vacuum or suction dredge equipment in California under the Fish and Game Code, effective April 27, 2012. (2012 Cal. Reg. Notice Register, No. 19-Z, p. 641 (May 11, 2012).) Notwithstanding the regulation, the use of vacuum or suction dredge equipment as defined is currently prohibited by statute in all California rivers, streams, and lakes. (Fish and G. Code, 5653.1, subd. (b); see also Id., 5653, subd. (g) (definition).) It is also unlawful under current law to possess a vacuum or suction dredge in areas, or in or within 100 yards of waters, that are closed to the use of such equipment. (Id., 5653, subd. (e).) This dataset is an approximate depiction of the Class closures and restrictions in California Code of Regulations, Title 14, section 228.5. Members of the public considering the use of vacuum or suction dredge equipment are responsible for knowing the exact regulation language that applies to any specific location in California. For current information regarding the lawful use of vacuum or suction dredge equipment in California please see Here

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for Californias 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.
