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$, and ~Stephanomeria lactucina$.
