Distinctiveness (1=highest,4=lowest): 1
This ecoregion contains a mosaic of communities, including grasslands, chaparral shrublands, open oak savannas, serpentine communities, closed-cone pine forests, wetlands, and salt marshes. Some of these communities are unique to California. The ecoregion supports a relatively large number of endemic plant and animal species. *
Conservation Status (1=most endangered, 5=most
intact): 3 (vulnerable)
Approximately 30% of the ecoregion is intact, concentrated in steeper areas. Fragmentation by development, fire supression, overgrazing, conversion to annual grasses, and introduction of invasive species are threats.*
