Name: Nassella viridula Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This grassland is found on mesic, meadow-like lower slopes and swales in the foothills of the Colorado Front Range. Stands often grow in narrow zones bordered by communities dominated by shrubs such as Symphoricarpos and Prunus in the north, and Quercus gambelii south of the Palmer Divide. It is dominated by Nassella viridula, often growing in nearly pure stands, with other mid grasses such as Koeleria macrantha (= Koeleria cristata), Pascopyrum smithii, and Poa spp. Common forbs are Frasera speciosa, Thermopsis divaricarpa (= Thermopsis rhombifolia var. divaricarpa), Achillea millefolium, and Symphyotrichum laeve var. geyeri (= Aster laevis var. geyeri). It is often bordered by shrub communities. The soils are coarser textured and deep, and stay moist until late summer (Vestal 1914, Weaver and Albertson 1956).  Accession Code: VB.CC.27413.NASSELLAVIRIDUL Plot-observations of this Community Concept: 0
