The Marin County standardized update area map is a fine scale vegetation map for 47,334 acres of public lands in Marin County. Figure 1 below shows the extent of these lands. The older fine scale maps exist in several different GIS datasets; this effort unifies them into a single dataset with a standardized set of attributes. This data product is meant to be used to understand vegetation conditions and how they changed between 2004 and 2014 for this subset of Marin County public lands. The new 2018 countywide fine scale vegetation map should be used for analysis and mapping of post-2014 vegetation conditions. <\/SPAN><\/P>

The original maps that were standardized and updated in this project include fine scale vegetation maps of Marin County Park lands (shown in magenta in figure 1), and maps of Marin Municipal Water District (MMWD) lands (shown in gray and green in figure 1). The original vegetation maps were based on high resolution aerial photography from 2004, 2009, and 2014. The fine scale map classes, which represent vegetation types mainly at the alliance level, are based on the Manual of California Vegetation. The original vegetation maps and their associated metadata are available from the California Department of Fish and Wildlife.
