Name: Artemisia tridentata ssp. vaseyana / Bromus tectorum Ruderal Shrubland Reference: NatureServe Biotics 2019 Description: <i>Artemisia tridentata ssp. vaseyana</i> dominates the canopy of this shrubland association. Other shrubs such as <i>Purshia tridentata, Ericameria nauseosa, Chrysothamnus viscidiflorus</i>, and <i>Artemisia arbuscula</i> are also common in the shrub stratum. Total plant cover of this community is generally less than 25%. The herbaceous understory ranges from sparse to moderate in terms of cover and is strongly dominated by the introduced annual grass <i>Bromus tectorum</i>. Native grasses are sparse and variable; only <i>Poa secunda</i> occurs with regularity, albeit at low cover values. Species richness of the forb component of this plant community is generally low. Forbs have highly variable species composition that may include both native and non-native species and those that are present usually have very sparse cover. <i>Artemisia tridentata ssp. vaseyana</i>-dominated shrublands occupy the most cool and moist climate zones of the <i>Artemisia tridentata</i> shrubland and shrub herbaceous alliances. The climate regime is cool, and semi-arid to subhumid. Much of the yearly precipitation falls as snow, which may cover the ground for long periods in winter. Landscape positions are variable as well, but primarily are deep-soiled to stony flats, ridges, nearly flat ridgetops, and mountain slopes. Soils generally are moderately deep to deep, well-drained, and comprised of loam, sandy loam, clay loam, or gravelly loam textural classes; they often have a substantial volume of coarse fragments.  Accession Code: urn:lsid:vegbank.org:commConcept:34234-{53A30B6B-57E6-4AB2-B2F1-3C3AB3E85CA1} Plot-observations of this Community Concept: 0
