Name: Ericameria nauseosa / Bromus tectorum Ruderal Shrubland Reference: Western Ecology Working Group of... Description: This shrubland occurs in disturbed situations at moderate altitudes in the Colorado Plateau; it extends into the Great Basin and is likely widespread in disturbed areas across the western U.S. Most stands are the result of fire burning sagebrush or other types of shrublands, but some derive from other forms of disturbance, including overgrazing. Elevations range from 1220 to 2085 m (4000-6840 feet), and sites occur on gentle to steep slopes. Sites include intermittently flooded drainages, stream terraces and broad floodplains, basins and upland slopes. Soils are variable; most stands occur on well-drained sandy loams that are often rocky, but others occur on loam or gravely clay or clay loam soils. Total vegetation cover is relatively sparse to dense, depending primarily on the density of cheatgrass in any given year. The shrub canopy is open to moderately dense, consisting of <i>Ericameria nauseosa</i> with 10-60% cover. Scattered individuals of other shrub species such as <i>Artemisia tridentata, Rhus trilobata, Atriplex canescens</i>, and <i>Atriplex confertifolia</i> may be present. The herbaceous layer contains many species but is overwhelmingly dominated by <i>Bromus </i><i>tectorum</i>. Relict native herbaceous grasses include <i>Aristida purpurea</i><i>, Achnatherum hymenoides, </i><i>Elymus elymoides, </i><i>Poa fendleriana</i>, and <i>Sporobolus cryptandrus</i>. Native herbaceous species are also common but contribute only sparse cover and may include <i>Cleome lutea, Eriogonum inflatum</i>, and <i>Heterotheca villosa</i>. Weedy forbs are more abundant in most stands, including <i>Descurainia pinnata, Lappula occidentalis</i>, and <i>Salsola tragus</i>.  Accession Code: VB.CC.33769.CEGL002937 Plot-observations of this Community Concept: 0
