CEGL003565 Ceanothus megacarpus - Adenostoma fasciculatum Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bigpod Ceanothus - Chamise Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association occurs on somewhat steep to steep slopes of variable aspect at low elevations between 0 and 688 m. It is characterized by the dominance of Ceanothus megacarpus and subdominance (averaging about half as much cover) of Adenostoma fasciculatum in the shrub layer. The herbaceous layer is insignificant. The emergent tree layer may infrequently include Quercus agrifolia.
Diagnostic Characteristics: No Data Available

Classification Comments: Historically, the balance between the Adenostoma fasciculatum (and related Adenostoma fasciculatum codominant alliances such as Adenostoma fasciculatum - Salvia mellifera) and the Ceanothus megacarpus alliance may have been different. Early mapping by the U.S. Forest Service VTM crews (John Tiszler, Robert Taylor pers. comm. 2003) suggests that in the 1930s the predominant chaparral stands were dominated or codominated by Adenostoma fasciculatum. However, currently others (Franklin 1998, Keeler-Wolf and Evens 2006) suggest that Ceanothus megacarpus-dominated chaparral has taken over as the principal cover of chaparral. The interface of these two main dominance types occurs in associations such as this one. Thus, monitoring plots within such stands may afford a more complete understanding of overall trends of vegetation dominance within the area.
