Name: Andropogon hallii - Carex inops ssp. heliophila Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This sand bluestem prairie community type is found in restricted areas of the northern Great Plains of the United States. Stands occur on gently to steeply sloping terrain with sand or sandy loam soil. In Montana, stands occur on slopes of any aspect, but north is the least likely. In North Dakota, they occur on steep, choppy sands. The vegetation is very open, ranging from 15-50% cover. The taller herbaceous stratum of this community is dominated by Andropogon hallii, with associates of Calamovilfa longifolia, Hesperostipa comata (= Stipa comata), and Sporobolus cryptandrus. In southeastern North Dakota Koeleria macrantha, Redfieldia flexuosa, and Hesperostipa spartea (= Stipa spartea) are present at low abundance. The lower herbaceous stratum is dominated by Carex spp., especially Carex inops ssp. heliophila. Other species that may be present are Artemisia frigida, Carex filifolia, Carex duriuscula, Dalea villosa, and Yucca glauca. Key diagnostic characteristics include the choppy sand dune habitat, the very open structure of the vegetation, dominance by Andropogon hallii with Carex inops ssp. heliophila and the presence of early successional species, such as Redfieldia flexuosa.  Accession Code: VB.CC.25926.ANDROPOGONHALLI Plot-observations of this Community Concept: 0
