Name: Aristida purpurea Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This purple three-awn grassland association occurs widely in the interior western U.S. and the western Great Plains. This semi-arid grassland is found on a variety of sites, such as western shortgrass prairie, intermountain basins, alluvial flats, and a Pleistocene lake bench. Substrates are often sandy or gravelly soils. The vegetation is characterized by the dominance of <i>Aristida purpurea</i> in a sparse to open grass layer. Associates vary depending on the pre-disturbance community, but frequently include other dry, grazing-tolerant grasses such as scattered <i>Bouteloua gracilis, Poa secunda</i>, or <i>Sporobolus cryptandrus</i>; occasional shrubs that my be present include <i>Ericameria nauseosa</i> or <i>Gutierrezia sarothrae</i> that are common in disturbed areas, or remnants of late-seral communities such as <i>Artemisia tridentata ssp. tridentata</i>. Introduced species may be common, such as <i>Bromus </i><i>tectorum</i> in disturbed stands.  Accession Code: VB.CC.34389.CEGL005800 Plot-observations of this Community Concept: 0
