This layer was created to aid SWR biologists in establishing Critical Habitat for Chinook in the Central Valley Spring-run ESU. The layer represents an approximation of Chinook occupancy and habitat quality in the region and is best suited for mapping those properties in the aforementioned region.
'CVSR_Chinook_Distribution_06_2005' depicts Chinook presence as well as habitat type and quality in the Central Valley Spring-run Evolutionary Significant Unit (ESU). The data was compiled by the National Marine Fisheries Service (NOAA Fisheries) Southwest Regional Office (SWR) in an effort to designate Critical Habitat for Chinook in California. The linework for this layer is based on the California Department of Fish and Game (CDFG) and Pacific States Marine Fisheries Commission (PSMFC) 1:100,000 scale stream based routed hydrography. SWR biologists divided the routed hydrography into stream segments using the best available information to represent local Chinook distribution and habitat. As a result, each segment has its own unique identifier (GIS_Link) and related presence and habitat information. The data set is in shapefile format and can be included as a map layer in a GIS. This data set is an update of 'CVSR_Chinook_Draft_2004'
Data layers from the following were used as basemap layers or as detailed in the 'Process Description' section during the designation process: California Department of Fish and Game, Pacific States Marine Fisheries Commission,California Geospatial Information Data Library, State Coastal Conservancy, California Department of Forestry, US Geological Survey
