CEGL002865 Quercus agrifolia / Salvia leucophylla - Artemisia californica Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Live Oak / San Luis Purple Sage - Coastal Sagebrush 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 slopes that are often north-facing at elevations between 53 and 420 m. It is dominated by Quercus agrifolia in the tree layer, Salvia leucophylla and Artemisia californica 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: This association is similar to the Quercus agrifolia / Artemisia californica / Grass association reported by Allen et al. (1991). It is likely to be the "parent" suballiance to this association. It is identified from Santa Clara to San Diego counties, with Artemisia californica as the overall constant shrub at 88% and Salvia leucophylla at 13% constancy. However, since Artemisia californica has a much wider geographic range than Salvia leucophylla, it is likely that if they had analyzed their southern California samples separately, they would also have shown a higher constancy of Salvia leucophylla, thus mirroring the Santa Monica Mountains situation.

Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form a sparse to intermittent tree layer (8-35%, mean 19.3%) with hardwoods at 2-15 m tall, an open to intermittent shrub layer (10-50%, mean 27.5%) at 0-5 m tall, and a sparse to open herbaceous layer (0-22%, mean 5.6%) at 0-1 m tall. Total vegetation cover is 32-64%; mean cover is 49.9%. In this association, the tree layer is dominated by Quercus agrifolia. Juglans californica is occasionally included in this layer. The open to intermittent shrub layer is dominated by Salvia leucophylla and Artemisia californica. Occasionally, Malosma laurina and Malacothamnus fasciculatus are also included. The herbaceous layer is diverse and includes Leymus condensatus, Brassica nigra, Bromus diandrus, and Centaurea melitensis.
