Name: Agropyron cristatum Semi-natural Herbaceous Alliance
Reference: Midwestern Ecology Working Group...
Description: This introduced-species grassland alliance occurs throughout the northwestern Great Plains of the United States and adjacent Canada. It is likely more widespread because it has been planted into pastures to improve forage production and is well suited to the cold, semi-arid conditions of the northwestern Great Plains and higher elevation rangeland in more southern latitudes. Stands can occur in a wide variety of human-disturbed habitats, including highway rights-of-way, revegetation projects, etc. The vegetation is characterize by a moderately dense to dense herbaceous layer dominated by medium-tall (0.5-1 m) perennial graminoids. The dominant grass is Agropyron cristatum, a naturalized species from the plains of Siberia. Other weedy species may occur as well, but native species are generally less than 10% cover. Native species may include mixed-grass prairie grasses, such as Pascopyrum smithii and Hesperostipa comata (= Stipa comata), as well as others. Where native species are conspicuous enough to identify the native plant association that could occupy the site, the stand should be typed as such.
