Name: Atriplex canescens Shrubland Reference: Western Ecology Working Group of... Description: This shrubland association is known from the Great Basin north into the southern Columbia Basin and east into Wyoming and the Colorado Plateau. It is common at middle elevations on alluvial fans and toeslopes in deep, sandy soils but will occur at lower elevations along alluvial benches where soils are often finer-textured and possibly saline/alkaline. Parent materials are variable. The vegetation is characterized by a sparse to moderately dense short-shrub layer (10-35% cover) dominated or codominated by <i>Atriplex canescens</i>, typically with a variable and often sparse herbaceous layer. Notable codominants in the shrub layer include <i>Chrysothamnus viscidiflorus, Coleogyne ramosissima, Ephedra nevadensis, Eriogonum nummulare (= Eriogonum kearneyi), Grayia spinosa, Gutierrezia sarothrae, Lycium pallidum</i>, or <i>Psorothamnus</i> spp. <i>Artemisia bigelovii, Artemisia tridentata</i>, and <i>Ephedra viridis, Krascheninnikovia lanata</i>, or <i>Purshia stansburiana</i> may be present but are not codominants. The herbaceous layer includes low cover of species such as <i>Achnatherum hymenoides, Aristida purpurea, Elymus elymoides, Pleuraphis jamesii</i>, and <i>Sporobolus cryptandrus</i>. Introduced species, especially <i>Bromus tectorum, Bromus diandrus</i>, and <i>Salsola kali</i>, are common on disturbed sites and can create an herbaceous layer much denser than on undisturbed sites. Winter annual forb cover is variable depending on annual precipitation.  Accession Code: VB.CC.34308.CEGL001281 Plot-observations of this Community Concept: 0
