Name: Grayia spinosa Scrub Alliance
Reference: NatureServe Biotics 2019
Description: Vegetation in this alliance occurs throughout the lower to middle elevations (600-1600 m) of the Great Basin and the eastern Mojave Desert. The vegetation is more drought-tolerant than <i>Artemisia tridentata</i>-dominated communities and typically occurs where local climate or salty soils create high moisture stress. This alliance is characterized by a sparse to moderately dense shrub layer of <i>Grayia spinosa</i>. Shrub associates include <i>Artemisia nova, Artemisia tridentata, Atriplex confertifolia, Atriplex canescens, Chrysothamnus</i> spp., <i>Coleogyne ramosissima, Ephedra nevadensis, Ephedra viridis, Larrea tridentata, Picrothamnus desertorum</i>, and <i>Prunus andersonii</i>. The herbaceous layer is typically sparse with <i>Achnatherum hymenoides, Achnatherum speciosum, Elymus elymoides, Navarretia</i> spp., <i>Pleuraphis jamesii</i>, and <i>Poa secunda</i> being common associates. Stands usually occur on mountain slopes or alluvial fans bordering intermountain basins. Soils are highly variable, but are generally coarse-textured and well-drained, and often alkaline.
