Name: Pascopyrum smithii - Nassella viridula Northwestern Great Plains Grassland Alliance
Reference: NatureServe Biotics 2019
Description: This alliance is found in the northern Great Plains from the southern Prairie Provinces of Canada to Colorado and western Nebraska. Midgrasses are dominant, especially <i>Pascopyrum smithii</i>. Other common species are <i>Elymus lanceolatus, Nassella viridula, Koeleria macrantha</i>, and <i>Hesperostipa comata</i>. The short graminoids <i>Bouteloua gracilis, Carex filifolia, Carex inops ssp. heliophila, Carex duriuscula</i>, and the exotics <i>Bromus racemosus</i> and <i>Bromus tectorum</i> can contribute substantial cover. Shrubs and scattered trees can often be found in the mesic settings occupied by this alliance. It usually occurs on fine-textured soils in mesic settings. Some stands can be on deep sandy soils. It is often in swales or valleys but can also be on rolling uplands.
