Name: Atriplex obovata / Sporobolus airoides - Sporobolus cryptandrus Dwarf-shrubland Reference: NatureServe Biotics 2019 Description: This association has only been described from a small area of the upper Rio Puerco watershed of northwestern New Mexico. It occurs in a semi-arid basin between 1647 and 1830 m (5400-6000 feet) elevation and is found on alluvial flats, with 0-2% slopes and fine-textured alluvial parent materials. Soils are calcareous Typic Torrifluvents, with clay, fine sandy loam, or silty clay loam textures. This is a sparsely vegetated dwarf-shrubland, with total plant cover &lt;20%. The dwarf, evergreen shrub <i>Atriplex obovata</i> is the dominant species. Other shrubs with trace cover include the succulents <i>Cylindropuntia imbricata, Opuntia polyacantha</i>, and the deciduous dwarf-shrub <i>Krascheninnikovia lanata</i>. Several perennial grass species may be present; <i>Sporobolus airoides</i> is the most constant and abundant, with <i>Sporobolus cryptandrus</i> and <i>Pleuraphis jamesii</i> typically present. Total herbaceous cover averages 4-6%, with forbs contributing only trace amounts. Species diversity is very low.  Accession Code: urn:lsid:vegbank.org:commConcept:30356-{A03D78C1-CC97-4818-8F69-C52BA886F41B} Plot-observations of this Community Concept: 0
