Name: Atriplex canescens / Sporobolus airoides Shrubland Reference: Western Ecology Working Group of... Description: This shrubland occurs in the northern Chihuahua Desert extending into the Trans-Pecos of Texas, southwestern Great Plains, and Colorado Plateau. Stands are found in washes and on alluvial flats, extending up lower slopes of alluvial fans or bajadas. Sites are level to gently sloping. Substrates are typically moderately deep, alkaline, calcareous, fine-textured soils. Cover of bare soil can be high (>50%). The vegetation is characterized by an open to moderately dense (10-50% cover) short-shrub layer dominated by Atriplex canescens with a perennial graminoid layer dominated by Sporobolus airoides. The shrub layer has greater cover than the herbaceous layer, which may include other scattered shrubs and dwarf-shrubs such as Artemisia filifolia, Atriplex confertifolia, Atriplex obovata, Chrysothamnus viscidiflorus, Ericameria nauseosa, Gutierrezia sarothrae, Isocoma pluriflora, Krascheninnikovia lanata, Lycium spp., Opuntia spp., Prosopis glandulosa, and Sarcobatus vermiculatus. Associated herbaceous species such as Elymus elymoides, Pascopyrum smithii, Pleuraphis jamesii, Sphaeralcea coccinea, Sporobolus cryptandrus, Sporobolus nealleyi, and Suaeda spp. may be present. Bouteloua gracilis cover is minor and inconsistent. Diagnostic of this Atriplex canescens-dominated shrubland is a Sporobolus airoides-dominated herbaceous layer.  Accession Code: VB.CC.21360.ATRIPLEXCANESCE Plot-observations of this Community Concept: 0
