Vegetation - Molok Luyuk (Walker Ridge) [ds3159]

Under contract to the U.S. Bureau of Land Management (BLM), Aerial Information Systems, Inc. (AIS) conducted vegetation classification development, fine-scale vegetation mapping, and accuracy assessment (AA) of approximately 22,061 acres within Colusa and Lake counties of California, under Contract GS00F170GA-Order No.140L1221F0044. AIS subcontracted the California Native Plant Society (CNPS) to conduct classification development work needed for this project, as well as AA field data collection. The California Department of Fish and Wildlife’s (CDFW) Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate AA sample sites and score the vegetation map using the AA data. Riparian vegetation and wetland types were mapped to a 1/4-acre MMU. Polygons representing land use were mapped with a 1-acre MMU. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS).
