Name: Atriplex canescens - Artemisia tridentata Shrubland Reference: Western Ecology Working Group of... Description: This shrubland is found on the western slope of the Colorado Rocky Mountains, Colorado Plateau, Great Basin, and Mojave Desert. Elevation ranges from 1160-2100 m (3800-6900 feet). Stands occur on level plains, valley bottoms, alluvial flats, stream terraces, low and midslopes . Slopes are typically less than 25%, but this shrubland has been documented on steep slopes as well. It occurs on all aspects, Substrates are well-drained, typically fine-textured soils (silty loam and clay) but may include coarser-textured soils (loamy sand). The vegetation is characterized by a sparse to moderately dense (10-35% cover) short-shrub layer that is codominated by <i>Atriplex canescens</i> and <i>Artemisia tridentata</i>. On some sites, <i>Pinus edulis</i> and/or <i>Juniperus osteosperma</i> canopy trees provide sparse cover. Associated shrubs include <i>Chrysothamnus viscidiflorus, Ephedra nevadensis, Ericameria nauseosa, Gutierrezia sarothrae, Gutierrezia microcephala, Krascheninnikovia lanata, Lycium</i> spp., and <i>Opuntia</i> spp. <i>Sarcobatus vermiculatus</i> and <i>Suaeda moquinii</i> may be present with low cover on more saline sites. The sparse to moderate herbaceous layer (10-20% cover) is dominated by graminoids with scattered forbs. <i>Achnatherum hymenoides, Bouteloua gracilis, Elymus elymoides</i>, and <i>Pascopyrum smithii</i> are common grasses. Forbs may include <i>Cirsium neomexicanum, Eriogonum inflatum, Eriogonum racemosum, Penstemon</i> spp., or <i>Sphaeralcea coccinea</i>. Introduced species are common in disturbed stands.  Accession Code: VB.CC.34054.CEGL001282 Plot-observations of this Community Concept: 0
