Name: A.833
Reference: EcoArt 2002
Description: The vegetation in this alliance occurs at middle elevations (800-2000 m) of the Intermountain West, usually in washes, on cliffs, or on steep, rocky terrain. Precipitation averages 20-45 cm annually. These communities occur on skeletal soils derived from granitic or sedimentary parent materials. In central Utah the alliance is associated with limestone. These shrublands are dominated by ~Purshia mexicana$, an erect evergreen shrub that grows up to 8 m tall, or ~Purshia stansburiana$. Associated shrubs include ~Ericameria nauseosa (= Chrysothamnus nauseosus), Coleogyne ramosissima, Artemisia tridentata$, and ~Yucca baccata$. The herbaceous ground layer is typically sparse, but can be moderately dense in stands which have been invaded by non-native annual grasses. Typical native species include ~Sporobolus cryptandrus, Poa secunda$, and ~Pseudoroegneria spicata$. Adjacent vegetation is usually ~Pinus - Juniperus$ woodlands, ~Quercus gambelii$ shrublands, or ~Artemisia tridentata$ shrublands.
