Name: Arctostaphylos patula Shrubland Alliance
Reference: Western Ecology Working Group of...
Description: These are montane shrublands found on the eastern slope of the Sierra Nevada and into the western Great Basin in summer dry habitats from 800-3000 m in elevation. Much of the precipitation comes as winter snow, but summer drought stress is characteristic. These shrublands are mostly found on steep, usually south-facing slopes, where soils are rocky and well-drained. These are typically zonal disclimax or, occasionally, edaphic climax brushfields which occur in association with dry needle-leaved evergreen forests or woodlands. These shrublands are typically established after stand-replacing fires or clearcut logging in Pinus ponderosa or Pseudotsuga menziesii forest, and are seral to forest after several decades. Excessively rocky or droughty, fire-prone sites in the forest may support relatively persistent stands of this alliance. These shrublands are strongly dominated by Arctostaphylos patula and may be almost monotypic. They are an important component of the Sierra Nevada/southern Cascade montane chaparral and may form large inclusions in dry pine forests following disturbance. Common shrub associates include Ceanothus velutinus, Ceanothus cordulatus, Arctostaphylos nevadensis, Chrysolepis sempervirens (= Castanopsis sempervirens), Cercocarpus montanus, and Ribes spp. Eastward, steppe species, such as Artemisia tridentata, Purshia tridentata, and Cercocarpus ledifolius, become common associates. Herbaceous vegetation is typically sparse and poorly described across the range of this alliance. Reported associates in northern California include Elymus elymoides, Pyrola picta, and Stephanomeria lactucina.
