Name: Artemisia tridentata ssp. wyomingensis / Pseudoroegneria spicata Shrubland Reference: Western Ecology Working Group of... Description: This association is common and widespread throughout the sagebrush zone of the western Great Plains through southern British Columbia, south into the Great Basin, northern Colorado Plateau, and western Wyoming. Slopes may be gentle to steep, and aspect is not important in determining the distribution of this association. Stands occupy moderately deep to deep loamy soils (often with coarse fragments), sometimes with a cemented clay layer limiting water and root penetration. Parent materials are variable. Throughout the geographic range of this type, <i>Artemisia tridentata ssp. wyomingensis</i> dominates a shrub layer that has at least 10% canopy cover. Total vegetation cover ranges between 20% and more than 100%, roughly evenly divided between the shrub and herbaceous strata. The shrubs <i>Chrysothamnus</i> spp., <i>Atriplex confertifolia, Purshia tridentata, Symphoricarpos longiflorus</i>, and <i>Amelanchier utahensis</i> are often present as well. The herbaceous understory is generally a diverse mix of grasses and forbs. <i>Pseudoroegneria spicata</i> contributes more cover to the diverse herbaceous layer than does any other native species, and <i>Achnatherum thurberianum, Festuca idahoensis, Hesperostipa comata, Poa secunda, Koeleria macrantha</i>, and <i>Poa fendleriana</i> are often present. Forbs are variable across the range of this type, but common species include <i>Eriogonum umbellatum, Sphaeralcea coccinea</i>, and <i>Balsamorhiza sagittata</i>. Stands in the eastern part of the geographic range often include <i>Gutierrezia sarothrae, Artemisia frigida</i>, and <i>Bouteloua gracilis</i>. The height of the sagebrush ranges from about 35 cm tall in the eastern part of the range to about 1 m tall in the western part.  Accession Code: VB.CC.34080.CEGL001009 Plot-observations of this Community Concept: 0
