Name: Ephedra torreyana / Pleuraphis jamesii Shrubland
Reference: NatureServe Biotics 2019
Description: This short shrubland occurs in the canyonlands of the Colorado Plateau of southern Utah and possibly Arizona. The vegetation ranges from 5 to 25% total cover and is characterized by an open canopy of <i>Ephedra torreyana</i> shrubs with up to 15% cover and the short bunchgrass <i>Pleuraphis jamesii</i> that ranges in cover from 1 to 5%. Associated shrubs <i>Atriplex gardneri</i> and <i>Coleogyne ramosissima</i> may be present to codominant. Other shrubs may include <i>Atriplex confertifolia, Ericameria nauseosa, Eriogonum microthecum, Opuntia</i> spp., and <i>Sclerocactus whipplei</i> The remaining herbaceous component includes grasses such as <i>Achnatherum hymenoides, Sporobolus cryptandrus</i>, and <i>Vulpia octoflora</i>, and the forbs <i>Amsonia tomentosa, Chenopodium album, Lepidium lasiocarpum, Plantago patagonica</i>, and <i>Streptanthella longirostris</i>. Biological soil crusts provide sparse cover in some stands. Stands are found typically on deep alkaline soils of plateaus, mesas, benches, lower slopes and stream terraces that are flat to moderately steep (up to 32% slopes) and occur between 1226 and 1506 m elevation. The unvegetated surface has high cover of bare soil and/or gravel with sparse cover of litter. Soils are rapidly drained loamy sands and clay loams.
