Name: Atriplex corrugata Low Scrub Alliance Reference: NatureServe Biotics 2019 Description: Stands have very sparse to moderate cover (5-30%) of woody vegetation that is dominated by the halophytic, evergreen dwarf-shrub <i>Atriplex corrugata</i>. Sparse stands are often completely dominated by this plant. Stands typically have very low species diversity. Depending on soil salinity and moisture, other plants may be present, including the shrubs <i>Krascheninnikovia lanata, Picrothamnus desertorum</i>, and <i>Tetradymia spinosa</i>. The herbaceous layer is very sparse. Scattered perennial forbs, such as <i>Sphaeralcea grossulariifolia</i> and <i>Xylorhiza glabriuscula</i>, and the perennial grass <i>Achnatherum hymenoides</i> have been reported. Annuals are seasonally present and may include <i>Eriogonum inflatum, Plantago tweedyi</i>, and the exotics <i>Bromus tectorum, Malcolmia africana</i>, and <i>Salsola kali</i>. Shrublands in this alliance are found on lower hillslopes and alkaline flats on the Colorado Plateau portions of northwestern New Mexico, western Colorado and Utah. Climate is semi-arid with most of the highly variable precipitation falling in July and August as high-intensity thunderstorms. Mean annual precipitation is approximately 23 cm. Elevation ranges from 1300-1820 m. Sites are nearly flat to moderately steep, and have soils typically derived from Mancos shale. Soils are moderately deep, strongly saline, moderately alkaline, fine-textured (clayey), poorly developed and typically have high erosion rates.  Accession Code: urn:lsid:vegbank.org:commConcept:38167-{68D3CB5A-0D29-40F9-8882-29B33ABC4A97} Plot-observations of this Community Concept: 0
