Name: Ephedra viridis / Pleuraphis jamesii Shrubland
Reference: NatureServe Biotics 2019
Description: This shrubland association is found in southeastern Utah on the Colorado Plateau. The vegetation is characterized by an open canopy of <i>Ephedra viridis</i> that ranges in cover from 5 to 55% and the short bunchgrass <i>Pleuraphis jamesii</i> that ranges in cover from 1 to 15%. If <i>Achnatherum hymenoides</i> and <i>Hesperostipa comata</i> are present, it is with much less cover than <i>Pleuraphis jamesii</i>. Associated shrubs include <i>Atriplex canescens, Gutierrezia sarothrae</i>, and <i>Opuntia polyacantha</i>. The herbaceous layer is diverse in terms of species composition and provides sparse to low cover. Associated graminoids include <i>Aristida purpurea, Bouteloua gracilis, Sporobolus airoides, Sporobolus cryptandrus</i>, and the annual exotic grass <i>Bromus tectorum</i>. Forbs commonly present include <i>Cryptantha crassisepala, Helianthus petiolaris, Lappula occidentalis</i>, and <i>Sphaeralcea parvifolia</i>. Total vegetation cover ranges from 6 to 85%. It occurs on partly stabilized dunefields and sandsheets on valley floors, plateau slopes, benches and mesatops. Sites are located on gentle slopes (3-10 %) between 1129 and 1850 m (3700-6070 feet) elevation. The rapidly drained, fine sandy loam, loamy sand, and sandy clay soils are derived from sandstones and shales, eolian deposits and alluvium.
