Name: Pascopyrum smithii - Nassella viridula Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This western wheatgrass - needlegrass community is common across much of the northern Great Plains of the United States and possibly Canada. Stands occur in narrow valleys, on stream terraces, and on rolling uplands. The soils are usually loams with well-developed profiles. It is dominated by mid grasses with a moderate to high vegetation cover. The dominant species are Pascopyrum smithii and Nassella viridula. Other mid grasses in this community are Elymus lanceolatus, Hesperostipa comata (= Stipa comata), Koeleria macrantha, Poa spp., Sporobolus cryptandrus, and, on sandier soils, Calamovilfa longifolia. Shorter graminoids are common, including Bouteloua gracilis, Carex duriuscula (= Carex eleocharis), Carex filifolia, and Carex inops ssp. heliophila. Where it is present within the range of this community, Carex pensylvanica may be abundant. The forbs Astragalus spp., Achillea millefolium, Sphaeralcea coccinea, Artemisia ludoviciana, and Lepidium densiflorum are also typical of this community.
