Hierarchy Level:  Association

Type Concept: This shrubland association occurs on somewhat steep to steep slopes of variable aspect at low to mid elevations between 17 and 821 m. It is dominated by both Adenostoma fasciculatum and Ceanothus crassifolius in the shrub layer, although Ceanothus crassifolius has typically somewhat higher cover. The herbaceous layer is sparse except for occasional vines of Marah macrocarpus, which may sprawl over the shrubs. Trees are generally absent.
