Type Concept: This shrubland association occurs on moderately steep to steep northeast- and northwest-facing slopes at low to mid elevations between 207 and 781 m. It is dominated by Adenostoma fasciculatum and Arctostaphylos glandulosa in the shrub layer and in the herbaceous layer. The emergent tree layer includes Quercus agrifolia.

Floristics: In western Riverside County, this association has Adenostoma fasciculatum and Arctostaphylos glandulosa consistently present, and both species are usually codominant, though sometimes Arctostaphylos glandulosa may be subdominant to Adenostoma fasciculatum. Other chaparral shrubs often intermix as subdominants, including Quercus berberidifolia, Heteromeles arbutifolia, and Garrya flavescens.

Environmental Description:  This association of California is found on north-facing slopes, outcrops, and ridges on shallow soils. Occurrences range in elevation from 300 to 2200 m. This alliance often follows disturbance, growing on sites that have been burned, logged, or otherwise disturbed.

Geographic Range: This association is known from the Santa Monica Mountains as well as several other mountain ranges of southern California, including the San Gabriel, San Bernardino, San Jacinto, and Peninsular ranges.
