MMWD lands support a startling array of plants, half of all the kinds of plants found in Marin grow on watershed lands, and 15% of California’s flora - in 0.02% of the area! Over 1,000 plant species combine in over 100 vegetation types, including several found nowhere else in the world.
Different aspects, soils, and moisture support communities from grassland and oak woodlands to chaparral, redwood forests, and wetlands. Our seam of serpentinite sustains several special status species seen solely on our slopes.
The Bay Area Open Space Council also has an online map system for exploring the diversity of lands in Marin and beyond. The California Department of Fish and Wildlife’s BIOS viewer has MMWD’s finer scale maps and background reports as well as others throughout the state.
