Vegetation - Suisun Marsh - 2021 [ds3187]

This is part of an ongoing monitoring project that the Biogeographic Data Branch (BDB) of the California Department of Fish and Wildlife (CDFW), in collaboration with the Department of Water Resources (DWR) and the CDFW Bay Delta Region (BDR), started in 1999 to track changes in the Suisun Marsh vegetation over time. This is the seventh update using the current mapping standards since the original map was made in 1999. Previous vegetation maps can be viewed and downloaded using the online CDFW Biogeographic Information and Observation System (BIOS) and the links to the associated reports included in the metadata. The reports can also be downloaded from the CDFW website (http://www.dfg.ca.gov/biogeodata/vegcamp/veg_classification_reports_maps.asp). The report associated with this map is available for download at: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=225327.

The final map covers 91,486 acres, containing vegetation and land use polygons ranging from 0.001 acres to 304 acres and averaging 1.7 acres. The tidally influenced acreage is covered by 6,665 vegetation polygons; 32,956 vegetation polygons cover the leveed acreage.
