Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Sycamore - California Live Oak / Mule-fat / Douglas'' Sagewort South Coast Riparian 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 often flat to gentle and occasionally somewhat steep slopes at elevations between 0 and 414 m. While slopes are usually flat, the association may occur with steepness on southeast or variable exposures. It is codominated by Platanus racemosa and Quercus agrifolia in the tree layer, Baccharis salicifolia in the understory shrub layer, and Piptatherum miliaceum is often in the herbaceous layer.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is likely to occur in other parts of south coastal California and is similar to the Platanus racemosa - Quercus agrifolia Central Coast association (Keeler-Wolf and Evens 2006).

Physiognomy and Structure: No Data Available
Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form a sparse to intermittent tree layer (8-40%, mean 20.3%) with hardwoods at 5-20 m tall, a sparse to intermittent shrub layer (1-36%, mean 16.7%) at 0-5 m tall, and a sparse to intermittent herbaceous layer (2-35%, mean 12.2%) at 0-1 m tall. Total vegetation cover is 29-75%; mean cover is 45.3%. In this association, the tree layer is dominated by Platanus racemosa and Quercus agrifolia. Juglans californica is occasionally included in this layer. The shrub layer is sparse to intermittent and is dominated by Baccharis salicifolia. Various other shrubs, such as Toxicodendron diversilobum and Sambucus nigra ssp. cerulea (= Sambucus mexicana), are occasionally included at low cover. The herbaceous layer is diverse and often includes Piptatherum miliaceum, Artemisia douglasiana, and Bromus diandrus. Other herbs include Hirschfeldia incana, Leymus condensatus, and Rubus ursinus.
