Description
State 1 represents the historic range of variability for this ecological site. This ecological site may be one of the few examples in California where historic plant communities are still observable. Ultramafic soils often offer a refuge to many native endemic herbaceous species because its unique soil chemistry is not amenable to the vast majority of plant species. Most of the endemic plants are still intact, despite the introduction of a number of annual grasses and forbs arriving after the discovery of the New World.
