Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Death Valley Joint-fir Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This scrub association is found at mid to upper elevations in the Mojave Desert and southern Great Basin in California. Vegetation is characterized by an open to patchy shrub canopy (4-38% cover) codominated by Ephedra funerea. Other shrubs that are often present to codominant include Ambrosia dumosa, Atriplex confertifolia, and Lycium andersonii. If present, the herbaceous layer is sparse to open and composed of scattered grasses and forbs such as Eriogonum inflatum, Xylorhiza tortifolia, and exotic annual grass Bromus rubens. Stands are found on variable slope positions ranging from 915 to 1755 m elevation. Sites occur on gentle to steep slopes (to 37°) on all aspects. Soils typically range from loamy sand to sandy clay and are derived from a variety of substrates such as conglomerate, dolostone (dolomite), granodiorite, rhyolite, and sandstone.
