Description: Vegetation and land use are mapped for the 737,621 acres constituting the Legal Delta portion of the Sacramento and San Joaquin River Delta area. Vegetation mapping is to alliance level when possible, otherwise it is left at group level (based on the National Vegetation Classification Standard, see http://biology.usgs.gov/npsveg/nvcs.html); land use is mapped to Anderson Level 2 classification (see https://pubs.usgs.gov/pp/0964/report.pdf). The map classification is based on a vegetation classification derived from field data collected in summer and fall of 2005 produced by the Vegetation Classification and Mapping Program (VegCAMP) of the Department of Fish and Game. Membership rules for each alliance can be foud at http://vegetation.cnps.org/. 2016 National Agricultural Inventory Program (NAIP) one meter orthoimagery was the baseline imagery used. Google Earth imagery was used as supplemental imagery. Natural vegetation comprises approximately 17 percent of the Delta study area, 65 percent is agriculture and pasture, 10 percent is urban/other and 8 percent is open water.Link to download report: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174866
