Name: Ephedra viridis / (Achnatherum hymenoides, Hesperostipa comata) Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland is known from southeastern Utah. The vegetation is characterized by an open canopy of clonal <i>Ephedra viridis</i> shrubs with between 5 and 20% cover with a well-developed grassy understory dominated by either <i>Achnatherum hymenoides</i> or <i>Hesperostipa comata</i>. The herbaceous layer totals up to 35% cover. Associated shrubs include scattered <i>Coleogyne ramosissima, Atriplex canescens, Eriogonum leptocladon</i>, and the succulent <i>Opuntia polyacantha</i>. Other grasses include <i>Aristida purpurea, Muhlenbergia pungens, Sporobolus cryptandrus</i>, and <i>Bouteloua gracilis</i>. If <i>Pleuraphis jamesii</i> is present, it is with much less cover than either <i>Hesperostipa comata</i> or <i>Achnatherum hymenoides</i>. Forbs include many species typical of sandy communities, including <i>Abronia fragrans, Chaenactis stevioides, Cymopterus newberryi, Oenothera pallida, Machaeranthera canescens, Plantago patagonica</i>, and <i>Sphaeralcea parvifolia</i>. Cryptogams are often present and provide up to 25% cover. Stands occur on sand dunes and sandsheets deposited on plateaus, benches and valley floors. Sites occupy gentle to moderately steep slopes (1-45%) between 1114 and 2018 m elevation. Soils are rapidly drained loamy sands and sandy loams derived from eolian sands or alluvial deposits.  Accession Code: urn:lsid:vegbank.org:commConcept:31262-{1092D3B9-1F7E-44B9-82E3-9C50924A961D} Plot-observations of this Community Concept: 0
