Description: This alliance includes both natural and semi-natural stands from localized areas across the northern Great Plains and throughout the western U.S. Naturally occurring stands have been described from areas of partially stabilized sands, in a region of actively moving dune deposits, from 1525-1800 m elevation in southeastern Idaho and in other areas of high natural disturbance such as on steep colluvial slopes, along drainages or in floodplains. The semi-natural stands included in this alliance are seral shrubland communities resulting from overgrazing by livestock, road building, or other cultural disturbance of typically grass-dominated communities. Elevations range from 1220-1800 m. Soils are variable, but generally well-drained and coarse-textured. The vegetation is characterized by a open to moderately dense, short-shrub layer (15-60% cover) that is dominated by ~Ericameria nauseosa$. Depending on geography, associated shrubs may include scattered ~Artemisia tridentata, Artemisia filifolia, Chrysothamnus viscidiflorus, Gutierrezia sarothrae, Rhus trilobata, Opuntia$ spp., ~Prunus virginiana, Symphoricarpos occidentalis$, and ~Yucca$ spp. The herbaceous layer can vary from moderately dense and dominated by graminoids to absent. Common native grasses include ~Achnatherum hymenoides (= Oryzopsis hymenoides), Bouteloua$ spp., ~Elymus trachycaulus ssp. trachycaulus, Leymus flavescens (= Elymus flavescens), Pascopyrum smithii, Pleuraphis jamesii, Pseudoroegneria spicata$, and ~Sporobolus cryptandrus$. Native forbs generally have low cover. Disturbed stands typically have high cover of introduced annual ~Bromus$ species.
