Name: Atriplex canescens Shrubland Reference: Western Ecology Working Group of... Description: This shrubland association is known from the Great Basin north into southern Columbia Basin and east into Wyoming and the Colorado Plateau. It is common on middle elevation bajadas in deep, sandy soils, but will occur at lower elevations along alluvial benches where soils are often finer-textured and possibly saline/alkaline. Parent material includes volcanic tuff, shale and sandstone. The vegetation is characterized by a sparse to moderately dense shrub layer (10-35% cover) dominated or codominated by Atriplex canescens typically with a variable and often sparse herbaceous layer. Notable codominants in the shrub layer include Chrysothamnus viscidiflorus, Coleogyne ramosissima, Ephedra nevadensis, Eriogonum nummulare (= Eriogonum kearneyi), Grayia spinosa, Gutierrezia sarothrae, Lycium pallidum, or Psorothamnus spp. Ephedra viridis may be present but is not a codominant. The typically sparse herbaceous layer includes low cover of species such as Achnatherum hymenoides, Aristida purpurea, Elymus elymoides, Pleuraphis jamesii, and Sporobolus cryptandrus. Common forb species on sandy sites include Cymopterus ripleyi, Dalea searlsiae, Lesquerella ludoviciana, and Oenothera pallida. Winter annual forb cover is variable depending on annual precipitation. Introduced species such as Bromus tectorum, Bromus diandrus, and Salsola kali are common on disturbed sites.  Accession Code: VB.CC.27810.ATRIPLEXCANESCE Plot-observations of this Community Concept: 0
