Name: Ephedra torreyana / Achnatherum hymenoides - Pleuraphis jamesii Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland is known from southeastern Utah. Total vegetation cover ranges from 5 to 25% which includes stands that are shrub-herbaceous in structure as well as shrublands and sparse vegetation. Vegetation composition is characterized by an open canopy of <i>Ephedra torreyana</i> that ranges between 2 to 25% cover, with an understory codominated by <i>Achnatherum hymenoides</i> and <i>Pleuraphis jamesii</i> with between 2 and 15% cover. Associated shrubs include <i>Atriplex canescens, Opuntia polyacantha</i>, and <i>Gutierrezia sarothrae</i>. The remaining herbaceous layer often includes <i>Astragalus amphioxys, Malacothrix sonchoides, Sporobolus airoides, Sporobolus flexuosus</i>, and <i>Sphaeralcea parvifolia</i>. This shrubland association occurs in large patches on broad sandy plains, as well as in smaller patches on knolls, toeslopes and pediments. Sites are flat to gentle (up to 8° slopes), occur between 1123 and 2000 m elevation, and tend to be oriented to warm south or west aspects. The unvegetated surface has up to 90% exposure of sand or bare soil. Parent materials include Entrada, Navajo, Summerville and Carmel formation materials that have eroded to alluvial or eolian sands and clays. Soils are rapidly drained to well-drained loamy sands where derived from secondary materials or sandy clays where derived from underlying shales.  Accession Code: urn:lsid:vegbank.org:commConcept:31260-{EA6B064A-B0F2-43B8-BF3F-FD1FFC0E42CA} Plot-observations of this Community Concept: 0
