Name: Atriplex obovata / Sporobolus airoides - Pleuraphis jamesii Shrub Grassland Reference: NatureServe Biotics 2019 Description: This association occurs on alluvial flats in the southern Colorado Plateau in northwestern New Mexico and adjacent Arizona at 1680-1811 m (5570-5940 feet) elevation. Slopes are minimal and range from 0-6%. Soils are typically shallow, alkaline, and calcareous and are derived from alluvium. Soil texture ranges from fine sandy loam to silty clay loam. Ground cover is largely bare soil, sometimes with high cover of surface rock, including basalt, gravel, and petrified wood. The vegetation is characterized by an open dwarf-shrub canopy of <i>Atriplex obovata</i> with a grassy understory dominated by <i>Pleuraphis jamesii</i> and <i>Sporobolus airoides</i>. Other shrubs may be present with very low cover, including <i>Atriplex confertifolia, Gutierrezia sarothrae, Krascheninnikovia lanata, Cylindropuntia imbricata, Opuntia polyacantha</i>, and <i>Sarcobatus vermiculatus</i>. Associated graminoids may include <i>Elymus elymoides, Muhlenbergia torreyi, Schedonnardus paniculatus</i>, and <i>Sporobolus cryptandrus</i>. Forb cover is typically low but may be diverse.  Accession Code: urn:lsid:vegbank.org:commConcept:30684-{B4A4CD96-9DFD-4D74-8050-A2D8E22697C0} Plot-observations of this Community Concept: 0
