Name: Atriplex corrugata Dwarf-shrubland Reference: Western Ecology Working Group of... Description: This dwarf-shrubland association is found on lower hillslopes, clay barrens and alkaline flats on Colorado Plateau portions of northwestern New Mexico, western Colorado and Utah. Sites are gently sloping to moderately steep ridges and hills shaped into badlands by water and wind erosion. Soils are typically derived from Mancos shale or other marine shales. They are moderately deep, strongly saline, moderately alkaline, fine-textured (clayey), poorly developed and typically have high erosion rates. The soil surface is mostly barren. The vegetation is characterized by a very sparse to moderate cover (5-25%) of woody vegetation that is dominated by the halophytic evergreen dwarf-shrub <i>Atriplex corrugata</i>. There is typically very low species diversity, but depending on soil salinity and moisture, other plants may be present, including the shrubs <i>Atriplex gardneri, Atriplex confertifolia, Tetradymia spinosa, Picrothamnus desertorum (= Artemisia spinescens), Suaeda calceoliformis (= Suaeda depressa)</i>, and <i>Krascheninnikovia lanata</i>. The herbaceous layer is very sparse. Only scattered perennial forbs, such as <i>Xylorhiza glabriuscula, Xylorhiza venusta</i>, and <i>Sphaeralcea grossulariifolia</i>, and the perennial grasses <i>Achnatherum hymenoides (= Oryzopsis hymenoides), Elymus elymoides</i>, and <i>Pleuraphis jamesii</i> have been reported. Annuals are seasonally present and may include <i>Eriogonum inflatum, Phacelia splendens, Plantago tweedyi</i>, and <i>Atriplex argentea</i>. Introduced species such as <i>Bromus tectorum</i> and <i>Salsola kali</i> are often present.  Accession Code: VB.CC.34406.CEGL001437 Plot-observations of this Community Concept: 0
