Description:
This sand prairie community is found in the northern and central Great Plains of the United States and Canada. Stands are found on sandy deposits, usually on gentle to moderate slopes, ranging from stabilized rolling to choppy sand dunes. The soil is sand, loamy sand, or sandy loam, often erodible, and somewhat poorly developed. This community is dominated by moderately widely spaced mid to tall grasses. The most abundant species are Andropogon hallii and Calamovilfa longifolia. Other graminoids that may be found in this community include Bouteloua gracilis, Bouteloua hirsuta, Carex duriuscula, Carex filifolia, Carex inops ssp. heliophila, Cyperus schweinitzii, Eragrostis trichodes, Hesperostipa comata (= Stipa comata), Koeleria macrantha, Muhlenbergia pungens, Redfieldia flexuosa, and Schizachyrium scoparium. Forbs and shrubs are a minor component of the total vegetation. Characteristic forbs include Chenopodium subglabrum, Chamaesyce serpyllifolia, Helianthus pauciflorus, Helianthus petiolaris, Lappula occidentalis var. occidentalis, Liatris punctata, Lithospermum incisum, Lygodesmia juncea, Monarda punctata, Oenothera rhombipetala, Penstemon haydenii (in Nebraska), and Psoralidium lanceolatum. Artemisia frigida and Yucca glauca are the most common shrubs, especially on wind-blown dune crests and choppy slopes in Nebraska sandhills. In southeastern North Dakota, a subtype containing tallgrass species may be distinct; species include Andropogon gerardii, Symphyotrichum ericoides (= Aster ericoides), Lithospermum canescens, Solidago nemoralis, and Sporobolus heterolepis.
