Name: Ericameria nauseosa / Bromus tectorum Ruderal Shrubland Reference: NatureServe Biotics 2019 Description: This ruderal shrubland occurs throughout much of the interior western U.S. in disturbed situations. 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 the non-native annual <i>Bromus tectorum</i>. Relict native herbaceous grasses include <i>Aristida purpurea, Achnatherum hymenoides, Elymus elymoides, 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>Lappula occidentalis</i>, and <i>Salsola tragus</i>. Stands occur on gentle to steep slopes with elevations ranging from 1110 to 2085 m (3640-6840 feet). 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. Most stands are the result of fire burning sagebrush or other types of shrublands, but some derive from other forms of disturbance, including overgrazing.  Accession Code: urn:lsid:vegbank.org:commConcept:31839-{0C30CD33-0652-40B1-82A2-3A3298D3D1FE} Plot-observations of this Community Concept: 2
