This grassland alliance is known only from stands in the rolling plains of southeastern Montana. Stands from Colorado in the ~Schizachyrium scoparium$ Herbaceous Vegetation association (former CEGL001680) were recently merged with an association, ~~Schizachyrium scoparium - Bouteloua curtipendula$ Loess Mixedgrass Herbaceous Vegetation (CEGL002036)$$, in the ~~Schizachyrium scoparium - Bouteloua curtipendula$ Herbaceous Alliance (A.1225)$$ leaving a single association, ~~Schizachyrium scoparium - Carex inops ssp. heliophila$ Herbaceous Vegetation (CEGL001682)$$. The moderate to dense herbaceous layer is dominated by the medium-tall, warm-season bunchgrass ~Schizachyrium scoparium$. The shorter graminoid, ~Carex inops ssp. heliophila$, typically codominates. Perennial forbs generally have sparse cover but may be relatively diverse. Annual forbs and grasses may be seasonally present. |

This alliance is found in the northwestern Great Plains and interior northwestern United States. This description is based largely on the type within this alliance that occurs in North and South Dakota. Stands of this alliance are found predominantly on floodplains or flat terraces near watercourses. The soils are derived from alluvial deposits and are often not well-developed. They are almost always loams, either sandy loams, silt loams, or clay loams. Flooding may occur periodically. Stands within this alliance are dominated by shrubs and graminoids approximately 1 m tall. Total vegetation cover is moderate. Graminoids make up the majority of the canopy, but the shrub layer is taller and thus more noticeable. ~Artemisia cana$ is the dominant, and often only, shrub in this stratum. ~Symphoricarpos occidentalis$ is present to common in some stands. There are also shorter shrubs such as ~Artemisia frigida, Krascheninnikovia lanata, Rosa woodsii$, and ~Gutierrezia sarothrae$. These rarely exceed 0.5 m. The most abundant midgrass in the Midwest is ~Pascopyrum smithii$, with smaller amounts of ~Nassella viridula, Hesperostipa comata (= Stipa comata), Koeleria macrantha$, and ~Poa pratensis$. The shortgrass ~Bouteloua gracilis$ is usually present and may be very common. Forbs are present but do not contribute much of the vegetation cover in this alliance. Among the forbs that are typically found in this alliance are ~Achillea millefolium, Gaura coccinea, Sphaeralcea coccinea, Lactuca tatarica var. pulchella$, and ~Taraxacum officinale$. |

This alliance, found in the western United States, occurs on flat to gently rolling sites, often with fine soils. Stands can be found on uplands or dry alluvial plains. The herbaceous layer is composed of moderately open to moderately dense mid grasses and short grasses. The shrub layer is typically 10-30% but may be higher in some stands. Pascopyrum smithii is the dominant species, typically accompanied by Bouteloua gracilis, Koeleria macrantha, Nassella viridula, Sphaeralcea coccinea, and Hesperostipa comata (= Stipa comata). Artemisia tridentata is the most abundant shrub. |
