Reference: EcoArt 2002
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).
