Sand sagebrush-mixed prairie is dominated by sand sagebrush and perennial warm-season grasses, including blue grama (Bouteloua gracilis), sand dropseed (Sporobolus cryptandrus), sand bluestem (Andropogon hallii), little bluestem (Schizachyrium scoparium), and sand paspalum (Paspalum setaceum).
The plant community is dominated by grasses, primarily prairie sandreed (Calamovilfa longifolia), little bluestem (Schizchyrium scoparium), sand bluestem (Andropogon hallu), switchgrass (Panicum virgatum), sand dropseed (Sporobolus cryptandrus), hairy grama (Bouteloua hirsuta), blue grama (Bouteloua gracilis), needle and-thread (Stipa comata), and prairie junegrass (Koeleria pyramidata) (Bragg and Steuter, 1996).

The functional groups and species added were: [C.sub.3] graminoids, Elymus canadensis, Koeleria pyramidata, Stipa comata, and Stipa spartea; [C.sub.4] graminoids, Andropogon gerardii, Bouteloua gracilis, Panicum virgatum, and Sporobolus cryptandrus; legumes, Baptisia lactea, Dalea purpureum, Lupinus perennis, and Vicia villosa; and nonleguminous forbs, Asclepias tuberosa, Coreopsis palmata, Echinacea purpurea, and Liatrus aspera.
The focus of this study was on the responses of five grass species: blue grama (Bouteloua gracilis), alkali sacaton (Sporobolus airoides), galleta grass (Pleuraphis jamesii) sand dropseed (Sporobolus cryptandrus), and three-awn (Aristida purpurea); and four shrub species: rabbitbrush (Ericameria nauseosa), sandsage (Artemisia filifolia), greasewood (Sarcobatus vermiculatus), and tree cholla (Cylindropuntia imbricata) over this decade of variation in moisture and temperature.

While current vegetation comprises a sparse cover of grasses and forbs with spotted knapweed being the dominant species, scattered occurrences of little bluestem, switchgrass, and sand dropseed (Sporobolus cryptandrus) suggest that the area may once have supported plant communities that included native warm-season grasses.
