CEGL003522 Adenostoma fasciculatum - Quercus berberidifolia Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Chamise - Scrub Oak Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association occurs on gentle to steep slopes of variable aspect at low elevations between 299 and 764 m. It is dominated by Adenostoma fasciculatum and Quercus berberidifolia in the shrub layer, with a sparse herbaceous layer. The emergent tree layer includes Quercus agrifolia.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: There is some confusion around the proper nomenclature for this association and the alliance it is within. The confusion comes from the inversion of the names of the two dominant and characteristic species. Adenostoma fasciculatum - Quercus berberidifolia association has been described by Gordon and White (1994), while the Quercus berberidifolia - Adenostoma fasciculatum alliance and association have been described by Sawyer and Keeler-Wolf (1995), Evens and San (2006), and Klein and Evens (2006). Both apparently refer to the same vegetation. The former association has been defined to describe the stands where Adenostoma fasciculatum clearly dominates but Quercus berberidifolia is present in low cover. This situation is more the norm for the Santa Monica Mountains stands. However, we have chosen to subsume this as an association within the broader mixed Quercus berberidifolia - Adenostoma fasciculatum alliance because of the overall similarity in species composition and environmental variables.

Physiognomy and Structure: No Data Available
Floristics: In addition to the codominance of Adenostoma fasciculatum and Quercus berberidifolia, a variety of coastal sage and chaparral shrubs (e.g., Rhamnus ilicifolia, Salvia mellifera, Lonicera subspicata, Rhus ovata, Heteromeles arbutifolia, Eriogonum fasciculatum) may occur at low cover in the open to continuous shrub layer.
Dynamics: No Data Available
Environmental Description: In the Los Padres National Forest of Monterey and San Luis Obispo counties (Borchert et al. 2004), the scrub oak-chamise alliance is common in the interior portions of the Coast Ranges, especially in the Sierra Madre and Garcia Mountains of the Santa Lucia Ranger District and in the eastern Monterey Ranger District. Most stands occur below elevations of 1100 m on middle and upper slope positions. Aspects vary but tend to be north-facing. Slopes are generally >20°.
Geographic Range: This association is known from the Santa Monica Mountains and several other areas within the central and southern coastal California region. This includes western Riverside (Klein and Evens 2005), San Diego (Evens and San 2005), Los Angeles, Santa Barbara, San Luis Obispo, Ventura, and Monterey counties (Gordon and White 1994, Borchert et al. 2004). It is probably most extensive in the Peninsular Ranges (western Riverside County: Santa Ana Mountains, San Jacinto Mountains and foothills; San Diego County: western foothills and Palomar - Cuyamaca Peak regions).
