Name: Arctostaphylos patula Sierran Chaparral Shrubland Reference: Western Ecology Working Group of... Description: This shrubland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. It is likely that this association ranges throughout the Sierra Nevada and perhaps elsewhere in montane California. Stands are found at low to mid elevations (1495-2530 m [4900-8300 feet]) on mid to high portions of slopes with all aspects. The slopes tend to be linear and moderately steep to abrupt (10-70°). This association is found on moderately deep to deep soils and occasionally on shallow soils. Soils are poorly drained to well-drained with textures ranging from stony and gravelly to loam from sedimentary and granitic parent materials. Although fires in this type can be small due to resistance to ignition, they can support catastrophic fires once they get started. The unvegetated surface is made up of litter, wood and bare soil. Disturbance in the form of invasion by exotics, logging, improper burning regime, and road and trail construction occur in low to high intensity. Most stands are the result of fire or other natural or unnatural process. Many stands could support conifer woodland or forest with long intervals between fires or other disturbance processes. This association forms open to moderately dense stands dominated by <i>Arctostaphylos patula</i>. Often found in this association are <i>Abies concolor, Calocedrus decurrens, Quercus kelloggii</i>, and <i>Chamaebatia foliolosa</i>. Occasionally, <i>Pinus jeffreyi, Quercus kelloggii</i>, and <i>Apocynum androsaemifolium</i> are present. A variety of other species present in this association may include <i>Carex multicaulis, Ceanothus parvifolius, Ceanothus cordulatus, Chamaesyce serpyllifolia, Lupinus breweri</i>, and <i>Prunus emarginata</i>. Stands of this association are variable in their disturbance regimes. Some are clearly seral to forest types, and others are edaphically controlled, probably persisting from 50 to more than 100 years at least without being invaded by conifers.  Accession Code: VB.CC.34285.CEGL005820 Plot-observations of this Community Concept: 0
