Name: Artemisia tridentata ssp. tridentata / Pascopyrum smithii - (Elymus lanceolatus) Shrubland
Reference: NatureServe Biotics 2019
Description: This widespread sagebrush shrubland occurs on valley bottoms, stream terraces and other relatively mesic sites west of the Great Plains throughout much of the intermountain western U.S. Stands occur over an elevational range of 1800-2410 m (5900-7900 feet). Most stands grow on alluvial terraces in stream alluvium, although a few occur on upland swales. Soils generally are loamy or sandy. Water tables may be within 2 m of the soil surface. The stream channel often is dry and may be incised. Soils are moderately well-drained sandy loam to sandy clay loam derived from alluvium. This association is characterized by a sparse to moderately dense short-shrub layer (up to about 40% canopy cover and to 1.5 m tall) that is dominated by <i>Artemisia tridentata ssp. tridentata</i>, with an herbaceous layer that is usually dominated by <i>Pascopyrum smithii</i> or <i>Elymus lanceolatus</i>. Other shrubs may be present in small amounts, especially <i>Artemisia tridentata ssp. wyomingensis, Chrysothamnus viscidiflorus, Ericameria nauseosa, Ericameria parryi, Krascheninnikovia lanata</i>, or <i>Quercus gambelii</i>. The sparse to dense herbaceous layer is dominated by graminoids and is poor in species richness relative to other sagebrush types. Other species that may be present in substantial amounts are <i>Achnatherum hymenoides, Achnatherum pinetorum, Bromus inermis, Elymus elymoides, Leymus cinereus, Muhlenbergia richardsonis, Poa fendleriana, Poa secunda</i>, and introduced species <i>Bromus inermis</i> and <i>Poa pratensis</i>. Forbs contribute much less cover than do grasses. Species that often occur are <i>Achillea millefolium, Astragalus</i> spp., <i>Erigeron compositus, Packera cana, Penstemon</i> spp., <i>Symphyotrichum ascendens</i>, and introduced species <i>Taraxacum officinale</i> and <i>Melilotus officinalis</i>.
