CEGL002860 Quercus agrifolia / Adenostoma fasciculatum Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Live Oak / Chamise Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is only known from the Santa Monica Mountains region. This woodland association occurs on somewhat steep to steep north-facing slopes at low elevations between 0 and 612 m. It is dominated by Quercus agrifolia in the tree layer, Adenostoma fasciculatum in the understory shrub layer, and a variety of grasses and forbs in the herbaceous layer.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Similar open woodlands of short Quercus agrifolia over Adenostoma fasciculatum have been seen in other parts of California (e.g., Monterey County) (T. Keeler-Wolf pers. obs. 2004) but have not been sampled. Quercus agrifolia / Chaparral association is described from western Riverside County in which the understory contains a mixture of chaparral species including Adenostoma fasciculatum. Further, Quercus agrifolia / Adenostoma fasciculatum - Salvia mellifera association, described from central California from Monterey south to Ventura County, is quite similar to this. In this type; Salvia mellifera only occurs in 62% of the samples. However, it is insignificant in the Santa Monica Mountains samples. Further descriptive work may show all of these types to be equivalent.

Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form a sparse to open tree layer (0-15%, mean 8.7%) with hardwoods at 5-15 m tall, an open to intermittent shrub layer (10-58%, mean 36.8%) at 01-5 m tall, and a sparse to intermittent herbaceous layer (0-40%, mean 11.3%) at 0-0.5 m tall. Total vegetation cover is 32-60%; mean cover is 50%. In this association, the tree layer is dominated by Quercus agrifolia. The open to intermittent shrub layer is dominated by Adenostoma fasciculatum. Frequently, Diplacus aurantiacus (= Mimulus aurantiacus), Malosma laurina, Ceanothus spinosus, Heteromeles arbutifolia, and Rhus ovata are also included. The herbaceous layer is simple and occasionally includes Melica imperfecta and Leymus condensatus.
