Name: A.1534 Reference: EcoArt 2002 Description: This alliance, found in the Rocky Mountains and western and northwestern Great Plains, is found in a dry to xeric landscape. Only one community within this alliance is found in the Midwest, and this description is based largely on that community. Stands in this alliance are found on sites that are more mesic than most of the surrounding area. Most of these sites are gentle to moderately steep, north-facing slopes, although other aspects are possible. The soils are shallow to deep and sandy loam to loam. There may be an impermeable layer of scoria, gravel, or sandstone beneath many of these sites. Some communities within this alliance have substantial amounts of exposed rock. Stands within this alliance are typically dominated by herbaceous species with a shrub canopy of 10-25%. Dominant herbaceous species are typically 0.5-1 m tall, while shrubs are closer to 0.5-0.7 m tall. The most abundant herbaceous species are mid grasses, such as ~Deschampsia caespitosa, Festuca idahoensis, Festuca altaica (= Festuca scabrella), Schizachyrium scoparium$, and short graminoids, such as ~Bouteloua gracilis, Carex$ spp., and ~Danthonia intermedia$ (in the western part of this alliance's range). Other graminoids that may be found with these species are ~Calamovilfa longifolia$ (in the east), ~Koeleria macrantha, Pascopyrum smithii$ (in the east), ~Pseudoroegneria spicata$, and ~Hesperostipa comata (= Stipa comata)$. ~Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda)$ is the most common shrub across this alliance's range with lesser amounts of ~Rhus aromatica$ and ~Symphoricarpos occidentalis$. In the eastern portion of its range ~Juniperus horizontalis$ is common to codominant.  Accession Code: VB.CC.1294.A1534 Plot-observations of this Community Concept: 0
