Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Creosotebush - Burrobush - Burrobrush Desert Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This scrub association is found at low to upper elevations in the Mojave Desert and southern Great Basin in California and southern Nevada. Vegetation is characterized by an open to moderate, often patchy shrub canopy (6-35% cover) codominated by Ambrosia dumosa and Larrea tridentata with Eriogonum fasciculatum characteristically present to codominant. Other shrubs frequently present include Krameria erecta, Viguiera parishii, and Yucca schidigera. If present, the herbaceous layer is sparse to moderate with native grasses and forbs and exotic annual grass Bromus tectorum. Stands occur on variable slope positions ranging from 100-1250 m elevation. Sites occur on gentle to moderate slopes on variable aspects. Soils include primarily sands and sandy loams that are derived from a variety of substrates such as alluvium, rhyolite, and sandstone.
