Name: Artemisia tridentata ssp. vaseyana / Leymus cinereus Shrubland Reference: NatureServe Biotics 2019 Description: This widely distributed association occupies shallow upland drainages associated with springs, slumps or seepage areas on hillslopes, as well as riparian terraces. Stands are small and isolated but occur throughout the sagebrush zone in the Great Basin, Wyoming Basins and Uinta Basin. Sites are located on gentle to moderate lee slopes (3-30%) that collect windblown snow and may be oriented to any aspect. Elevations range between 2100 and 2560 m (6890-8400 feet). Soils are deep, well-developed, moderately well-drained and variable in texture. The underlying substrate is sandstone, marlstone or shale. Shrub cover is lower in this association than in most mountain sagebrush types. <i>Artemisia tridentata ssp. vaseyana</i> dominates the shrub layer with at least 10% cover. Other shrubs present are <i>Symphoricarpos oreophilus, Tetradymia canescens, Chrysothamnus viscidiflorus, Rosa woodsii</i>, and <i>Ericameria nauseosa</i>. <i>Leymus cinereus</i> is the dominant grass, usually with at least 10% cover, although cover may be lower in stands that have been heavily grazed. Associated grasses include <i>Elymus lanceolatus, Bromus carinatus, Festuca idahoensis, Poa pratensis, Poa fendleriana</i>, and <i>Poa secunda</i>. Forb species contribute sparse cover and vary among sites. Common species include <i>Achillea millefolium, Balsamorhiza sagittata</i>, and <i>Phlox</i> spp.  Accession Code: urn:lsid:vegbank.org:commConcept:29936-{ADA6BD14-A47F-4DAD-BDD1-9AB105D478C5} Plot-observations of this Community Concept: 0
