CEGL005753 Hymenoclea salsola - Larrea tridentata Desert Wash Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Burrobrush - Creosotebush Desert Wash Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This desert scrub association is found at low to upper elevations in the Mojave Desert in California, Arizona and southern Nevada. Vegetation is characterized by an open to moderately dense shrub canopy (7-48% cover) dominated or codominated by Hymenoclea salsola with Larrea tridentata being codominant and Ambrosia dumosa often present. Occasional emergent Yucca brevifolia or Chilopsis linearis trees are sometimes present. If present, the herbaceous layer is typically sparse to open and composed of exotic annuals Erodium cicutarium and Schismus spp. Stands are found primarily in drainage channels, basins, and valley floors from 265-1425 m elevation. Sites typically occur on flat to gentle slopes on variable aspects, but occasionally are found on steep slopes. 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.

Floristics: Vegetation is characterized by an open to moderately dense shrub canopy (7-48% cover) dominated or codominated by Hymenoclea salsola with Larrea tridentata being codominant and Ambrosia dumosa often present (Evens et al. 2012, 2014). Occasional emergent Yucca brevifolia or Chilopsis linearis trees are sometimes present. If present, the herbaceous layer is typically sparse to open (to 22%) and composed of exotic annuals Erodium cicutarium and Schismus spp. (Evens et al. 2012, 2014).

Environmental Description: This desert scrub association is found at low to upper elevations in the Mojave Desert in California, Arizona and southern Nevada. It is found primarily in drainage channels, basins, and valley floors from 265-1425 m elevation (Evens et al. 2012, 2014). Sites typically occur on flat to gentle slopes on variable aspects, but occasionally are found on steep slopes (to 33°) (Evens et al. 2012, 2014). 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 (Evens et al. 2012, 2014).
Geographic Range: This association is found at mid elevations in the Mojave Desert and southern Great Basin in Arizona, California and southern Nevada, and was sampled in Death Valley National Park, Joshua Tree National Park, Lake Mead National Recreation Area, and Mojave National Preserve.
