Name: Atriplex confertifolia - Lepidium fremontii Shrubland
Reference: NatureServe Biotics 2019
Description: This association is found in the northern Mojave Desert and southern Great Basin of California. It forms an open to intermittent shrub canopy (5-43% cover) with <i>Atriplex confertifolia</i> codominant and with characteristic shrubs <i>Lepidium fremontii</i> and <i>Echinocactus polycephalus</i>. Other shrubs often present include <i>Ambrosia dumosa</i> and <i>Eriogonum fasciculatum</i>. Herbaceous cover is variable and ranges from 0 to 14% with commonly associated herbs <i>Dasyochloa pulchella, Dedeckera eurekensis, Eriogonum inflatum, Sphaeralcea ambigua, Stephanomeria pauciflora, Xylorhiza tortifolia</i>, and exotic grass <i>Bromus rubens</i>. A variety of annual herbs also occur seasonally. Nonvascular plants include cryptogamic crust. If present, emergent trees have sparse cover (&lt;3%). Stands occur primarily on rock outcrops, steep, rocky erosional slopes, and bedrock canyon walls at mid to upper elevations (850-1750 m). Sites range from gentle to steep (1-34°) slopes on variable aspects. Soils are variable but are primarily clay loams, but can include silty and sandy loams, and loamy sands. Soils are most often derived from sandstone and nutrient-poor limestone/dolomite but may include a variety of parent materials such as alluvium, limestone, rhyolite, and dolostone (dolomite).
