Name: Atriplex canescens / Pleuraphis jamesii Shrubland Reference: Western Ecology Working Group of... Description: This broadly defined shrubland association has been reported from the southwestern Great Plains, Colorado Plateau, Uinta Basin, and may occur in the Chihuahuan Desert and eastern California. As defined, this association occurs on two distinct types of landforms: alluvial flats and stream terraces with fine-textured soils, or on sand sheets and dunes with sand or sandy loam substrates. The alluvial soils are often deep, alkaline, saline silty clay loams. The vegetation is characterized by a sparse to moderately dense shrub layer (10-40% cover) dominated by Atriplex canescens with Pleuraphis jamesii dominating the herbaceous layer. Associated shrubs include Ericameria nauseosa, Ephedra torreyana, Chrysothamnus viscidiflorus, Krascheninnikovia lanata, Gutierrezia sarothrae, Artemisia bigelovii, or Opuntia polyacantha depending on substrate. Other graminoids include Achnatherum hymenoides and Sporobolus cryptandrus on sandy sites and Bouteloua gracilis and Sporobolus airoides on fine-textured soil. Forbs generally have low cover and may include Sphaeralcea grossulariifolia and Chenopodium spp. Introduced species such as Bromus tectorum and Salsola kali are common on some sites.  Accession Code: VB.CC.27880.ATRIPLEXCANESCE Plot-observations of this Community Concept: 0
