Reference: EcoArt 2002
Description: This alliance has been described from the eastern side of the Wind River Mountains in west-central Wyoming, the Shirley Mountains in central Wyoming, and the Laramie Mountains in southeastern Wyoming. It is found on slopes and ridges of low mountains and the margins of high-elevation basins from 1830 to 2745 m (6000-9000 feet) elevation. Stands occur on wind-swept gentle slopes and broad ridgetops, with coarse-textured (gravelly), well-drained shallow soils. The vegetation in this alliance consists of bunch-form and rhizomatous graminoids with forbs and scattered low-growing (<= 15 cm) shrubs. ~Artemisia tripartita ssp. rupicola$ typically contributes 10-20% cover. The most common graminoids are ~Festuca idahoensis$ (which may dominate or be a secondary species), ~Pseudoroegneria spicata$ (which often contributes the most cover), ~Leucopoa kingii$, and ~Poa$ spp. (~Poa fendleriana, Poa cusickii, Poa secunda$). Other common associated species are ~Koeleria macrantha$ and ~Carex filifolia$. Common forbs are ~Antennaria microphylla, Phlox hoodii, Artemisia frigida$, and ~Cerastium arvense$. ~Artemisia tridentata ssp. vaseyana$ or ~Artemisia tridentata ssp. wyomingensis$ may be present but contribute relatively little cover; ~Ericameria nauseosa$ also is often present.
