Name: Atriplex hymenelytra Scrub Alliance
Reference: NatureServe Biotics 2019
Description: Stands included in this alliance occur in valleys, bajadas and lower slopes of mountains in the Mojave Desert and characterized by a very sparse canopy of <i>Atriplex hymenelytra</i>. Vegetation included in this alliance has a very sparse canopy of <i>Atriplex hymenelytra</i> less than 1 m tall with scattered clumps of <i>Chamaesyce parishii</i> and <i>Tidestromia oblongifolia</i>. More mesic sites in drainages may support additional shrubs, including <i>Ambrosia dumosa, Baccharis sergiloides, Bebbia juncea, Dalea mollissima, Eriogonum inflatum, Hymenoclea salsola</i>, and <i>Larrea tridentata</i>. During wet years, annual forbs may be present. Adjacent vegetation is generally shrublands dominated by <i>Ambrosia dumosa</i> and <i>Larrea tridentata</i>. Sites are very arid because of topography or salts. The alliance is commonly found along drainages that dissect west-facing bajadas and on western slopes of mountains. Topography is typically flat and rolling to moderately sloping. There are large areas of desert pavement with very sparse vegetation. Soils are deep, well-drained, alkaline, and coarse-textured.
