Type Concept: This shrubland association has been described from the northern Sierra Nevada foothills, Santa Monica Mountains National Recreation Area, and Pinnacles National Monument, California. It occurs on moderately steep to steep slopes with rocky and occasionally deep soils on all aspects at elevations between 10 and 1800 m. It is characterized by a dominance of Cercocarpus montanus var. glaber in the shrub layer. The herbaceous layer has no characteristic species. The emergent tree layer may include infrequent Quercus agrifolia, Quercus wislizeni, Juglans californica, Platanus racemosa, Pinus sabiniana, and Umbellularia californica.
