Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Mojave Yucca - Buckhorn Cholla Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This desert scrub association is found at mid to upper elevations in Mojave Desert in California. It is characterized by an open to moderately dense shrub canopy (9-44% cover) codominated by Yucca schidigera and Cylindropuntia acanthocarpa with Acacia greggii, Echinocereus engelmannii, Ephedra nevadensis, Eriogonum fasciculatum, Ferocactus cylindraceus, and Viguiera parishii being characteristically present. Other shrubs are also often present. Occasional emergent Pinus monophylla trees are sometimes present with <1% cover. If present, the herbaceous layer is typically open and ranges to 22% cover. Commonly associated native grasses and forbs include Eriogonum inflatum, Pleuraphis rigida, Sphaeralcea ambigua, and exotic annuals include Bromus rubens and Erodium cicutarium. Stands occur primarily on low to midslopes at 850-1400 m elevation. Sites have gentle to steep slopes with southerly to southwesterly aspects. Soils are variable, ranging from silty clay to sandy loam derived from a variety of substrates.

Environmental Description: This desert scrub association is found at mid to upper elevations in Mojave Desert in California. Stands occur primarily on low to midslopes at 850-1400 m elevation (Evens et al. 2014). Sites have gentle to steep slopes (to 35°) with southerly to southwesterly aspects. Soils are variable, ranging from silty clay to sandy loam derived from a variety of substrates, but predominantly alluvium, gneiss, granodiorite, limestone/dolostone (dolomite), basalt, and rhyolite (Evens et al. 2014).
Geographic Range: This association is found at mid to upper elevations scattered across the central Mojave Desert including the Mojave National Preserve, California.
