Description:
This dry sand prairie community is widespread throughout the midwestern region of the United States and adjacent Canada. Stands occur on steep slopes, sandy outwash, sandy lake plains, and alluvial deposits. They may occur on sand ridges (including inland dunes and sandy areas of coarse-textured end moraines), where, particularly if blowouts have occurred, they may resemble sand barrens. Soils are well-drained to excessively drained, coarse-textured sands, loamy sands, and sandy loams. Gravels are very minor. Graminoids dominate the herbaceous layer, which can be open to closed. Dominant species include Carex pensylvanica, Danthonia spicata, Koeleria macrantha, Schizachyrium scoparium, and Hesperostipa spartea (= Stipa spartea). Other graminoids include Bouteloua hirsuta, Digitaria cognata (= Leptoloma cognatum) and Dichanthelium acuminatum var. fasciculatum (= Dichanthelium lanuginosum). In more open dune-like habitats Calamovilfa longifolia may be present. A wide variety of forbs are present including Asclepias verticillata, Ambrosia psilostachya, Artemisia frigida, Pseudognaphalium obtusifolium (= Gnaphalium obtusifolium), Euphorbia corollata, Hieracium longipilum, Lechea tenuifolia, Liatris aspera, Liatris cylindracea, Nuttallanthus canadensis (= Linaria canadensis), Lithospermum canescens, Lupinus perennis, Oenothera rhombipetala, Polygala polygama, Packera plattensis (= Senecio plattensis), Solidago nemoralis, Tephrosia virginiana and Viola pedata. Hudsonia tomentosa, and other sand barrens species, are more often restricted to local disturbances such as blowouts or slipfaces.
