CEGL002864 Quercus agrifolia / Quercus berberidifolia Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Live Oak / Scrub Oak 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 gentle to somewhat steep slopes with variable aspects at low elevations between 118 and 413 m. It is dominated by Quercus agrifolia in the tree layer, Quercus berberidifolia 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: A somewhat similar association, the Quercus agrifolia - Umbellularia californica / Heteromeles arbutifolia - Quercus berberidifolia association, has been defined. It differs from this association by having Umbellularia in >75% of the samples and Arbutus menziesii in about half of the samples. It is perhaps a northern California analog to this association.

Physiognomy and Structure: No Data Available
Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form an open to intermittent tree layer (12-38%, mean 23.1%) with hardwoods at 5-15 m tall, a sparse to intermittent shrub layer (9-50%, mean 28.6%) at 0-5 m tall, and a sparse to open herbaceous layer (0-18%, mean 7%) at 0-1 m tall. Total vegetation cover is 45-68%; mean cover is 57%. In this association, the tree layer is dominated by Quercus agrifolia. Juglans californica and Populus fremontii are occasionally included in this layer. The shrub layer is sparse to intermittent and is dominated by Quercus berberidifolia. Occasionally, Rhamnus ilicifolia, Ceanothus cuneatus, Heteromeles arbutifolia, Sambucus nigra ssp. cerulea (= Sambucus mexicana), and Cercocarpus montanus var. glaber (= Cercocarpus betuloides) are also included. The herbaceous layer is diverse and includes Bromus sp., Centaurea melitensis, Dryopteris arguta, and Dryopteris arguta.
