Name: Artemisia tripartita ssp. rupicola Shrub Herbaceous Alliance
Reference: Western Ecology Working Group of...
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.
