CEGL006857 Lycium andersonii Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Water Jacket Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This desert scrub association is found in Mojave Desert ranges in California and southern Nevada. It is characterized by an open shrub canopy (7-16% cover) strongly dominated by Lycium andersonii with Ambrosia dumosa, Atriplex confertifolia, and Larrea tridentata usually present. Other shrubs present include Krascheninnikovia lanata and Lepidium fremontii. Ephedra spp. are absent or have low cover. Occasional emergent Yucca brevifolia trees are sometimes present. The herbaceous layer is sparse to open and is composed of grasses and forbs such as Achnatherum speciosum, Astragalus spp., Eriogonum inflatum, Sphaeralcea ambigua, and exotic annual grass Bromus rubens. Stands occur primarily on gravelly to rocky, erosive slopes or washes at mid to upper elevations that range from 1000 to 1500 m. Sites are on gentle to moderate slopes on various aspects. Soils are loamy mixtures that are derived mostly from rhyolite and basalt substrates.

Floristics: The vegetation is characterized by an open shrub canopy (7-16% cover) that is strongly dominated by Lycium andersonii with Ambrosia dumosa, Atriplex confertifolia, and Larrea tridentata usually present (Evens et al. 2014). Other shrubs present include Krascheninnikovia lanata and Lepidium fremontii (Evens et al. 2014). Ephedra spp. are absent or have low cover. Occasional emergent Yucca brevifolia trees are sometimes present. The herbaceous layer is sparse to open (to 11% cover) and is composed of grasses and forbs such as Achnatherum speciosum, Astragalus spp., Eriogonum inflatum, Sphaeralcea ambigua, and exotic annual grass Bromus rubens (Evens et al. 2014).

Environmental Description: This desert scrub association is found in Mojave Desert ranges in California and southern Nevada. Stands occur primarily on gravelly to rocky, erosive slopes or washes at mid to upper elevations that range from 1000 to 1500 m (Evens et al. 2014). Sites are gentle to moderate slopes (to 20°) on various aspects. Soils are loamy mixtures that are derived mostly from rhyolite and basalt substrates, but also sandstone and tephrite (basanite) (Evens et al. 2014).
Geographic Range: This desert scrub association is found at mid to upper elevations in the Mojave Desert and southern Great Basin in California and southern Nevada and was sampled in Death Valley National Park and Mojave National Preserve.
