Reference:
NatureServe Biotics 2019
Description:
This desert wash scrub occurs at low to upper elevations in the Mojave Desert in California and southern Nevada and extends into the Colorado Plateau in Arizona. Vegetation is characterized by an open to moderately dense shrub canopy (7-48% cover) dominated or codominated by <i>Acacia greggii</i> with <i>Hymenoclea salsola</i> and <i>Larrea tridentata</i> being present to codominant. It is a wide-ranging type with many possible associates present such as <i>Adenophyllum cooperi, Ambrosia</i> spp., <i>Brickellia incana, Encelia virginensis, Ephedra nevadensis, Krameria erecta, Lycium</i> spp., <i>Cylindropuntia acanthocarpa, Opuntia basilaris, Salazaria mexicana, Salvia dorrii</i>, and <i>Yucca schidigera</i>. Occasional emergent <i>Yucca brevifolia</i> or <i>Chilopsis linearis</i> trees are sometimes present. If present, the herbaceous layer is typically sparse to open, composed of scattered <i>Cryptantha</i> spp., <i>Antheropeas lanosum, Chamaesyce polycarpa, Descurainia pinnata, Eriogonum plumatella, Mirabilis laevis var. villosa, Phacelia crenulata, Penstemon palmeri</i>, and <i>Vulpia octoflora</i>. Stands are found primarily in braided washes, arroyos, and drainage channels with up to 3-m high banks. Elevation ranges from 150-1350 m. Sites occur on flat to gentle slopes on variable aspects. Substrates are typically coarse-textured alluvial soils, usually sand or loam often with high cover of gravel on the surface. Soils are derived from a variety of substrates but primarily alluvium and granodiorite, and less often granite.
