Name: Purshia stansburiana Scrub Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of shrublands dominated by <i>Purshia stansburiana</i>. Associated shrubs include <i>Agave utahensis, Artemisia nova, Artemisia tridentata, Coleogyne ramosissima, Ephedra viridis, Ericameria nauseosa, Mortonia utahensis</i>, and <i>Yucca baccata</i>. The herbaceous ground layer is typically sparse and includes <i>Achnatherum speciosum, Poa secunda, Pseudoroegneria spicata</i>, and <i>Sporobolus cryptandrus</i>. Emergent <i>Juniperus osteosperma</i> and <i>Pinus monophylla</i> trees may be present. Stands occur throughout the Intermountain West at middle elevations (800-2000 m) on edges of intermittent watercourses, canyons, hills, steep slopes, and cliffs. Soils are well-drained, shallow, rocky, rapidly permeable, and usually calcareous, but it is known to occur on limestone. Precipitation averages 20-45 cm annually. The alliance in California is restricted to mountains of the eastern Mojave Desert and adjacent Great Basin. It occurs in small, scattered stands on relatively steep slopes, which are often adjacent to <i>Pinus monophylla</i> stands or <i>Artemisia tridentata</i> or <i>Purshia tridentata</i> shrublands. Virtually all stands observed occur on limestone or marble. Disturbance from flooding is likely in the canyon bottom stands.
