CEGL006863 Prunus fasciculata - (Purshia stansburiana, Viguiera reticulata) Desert Wash Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Desert Almond - (Stansbury''s Cliffrose, Netvein Goldeneye) Desert Wash Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is found at mid to upper elevations in the Mojave Desert and southern Great Basin in California and Nevada. Vegetation is characterized by an open to moderately dense, often patchy shrub canopy (8-36% cover) codominated by Prunus fasciculata and Purshia stansburiana with Viguiera parishii often present. Other shrubs are often present, including Acacia greggii. If present, the herbaceous layer is sparse to moderate. Commonly associated native grasses and forbs include Achnatherum speciosum, Artemisia ludoviciana, Dudleya saxosa, Elymus elymoides, Euphorbia schizoloba, Galium angustifolium, Melica frutescens, Mirabilis laevis var. villosa, Sphaeralcea ambigua, and exotic annuals include Bromus rubens and Erodium cicutarium. Stands are found primarily in middle to lower canyon bottoms on variable slope positions at 880-1885 m elevation. Sites are gentle to steep slopes on variable aspects. Substrates are typically coarse-textured soils derived from alluvium and limestone.

Floristics: Vegetation is characterized by an open to moderately dense, often patchy shrub canopy (8-36% cover) codominated by Prunus fasciculata and Purshia stansburiana with Viguiera parishii often present (Evens 2000, Evens et al. 2014). Other shrubs often present include Acacia greggii, Echinocereus engelmannii, Ephedra viridis, Gutierrezia sarothrae, Opuntia phaeacantha, Stephanomeria pauciflora, and Yucca baccata (Evens 2000, Evens et al. 2014). If present, the herbaceous layer is sparse to moderate, ranging up to 23% cover (Evens et al. 2014). Commonly associated native grasses and forbs include Achnatherum speciosum, Artemisia ludoviciana, Dudleya saxosa, Elymus elymoides, Euphorbia schizoloba (= Euphorbia incisa), Galium angustifolium, Melica frutescens, Mirabilis laevis var. villosa (= Mirabilis bigelovii), Sphaeralcea ambigua, and exotic annuals include Bromus rubens and Erodium cicutarium. Nonvascular plants include mosses (Evens 2000, Evens et al. 2014).

Environmental Description: This association is found at mid to upper elevations in the Mojave Desert and southern Great Basin in California and Nevada. It is found primarily in middle to lower canyon bottoms on variable slope positions at 880-1885 m elevation (Evens 2000, Keeler-Wolf et al. 2005). Sites are gentle to steep slopes (4 to 45°) on variable aspects. Substrates are typically coarse-textured soils derived from alluvium and limestone (Evens 2000, Evens et al. 2014).
Geographic Range: This association is found at mid to upper elevations in the Mojave Desert and southern Great Basin in California and Nevada and was sampled in Death Valley National Park and Mojave National Preserve.
