Vegetation - Marin Municipal Water District (MMWD) - 2014 [ds3130]

The primary purpose of the project was to find areas where vegetation had changed because of SOD and to show where gaps were formed by fallen oak trees. There was a total of 99 mapping classes. Vegetation with field questions map class is not symbolized in the cartography.

CNPS under separate contract and in collaboration with CDFW VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The 2009 vegetation map was updated applying heads-up digitizing techniques using a 2014 base of 6-inch resolution, natural color imagery provided by MMWD, in conjunction with custom ArcGIS tools that AIS developed to update the existing 2009 database.

Mapped polygons were assessed for change in Vegetation Type as a result of SOD. More information can be found in the project report which is bundled with the BIOS vegetation map.
