Name: Pseudoroegneria spicata - Bouteloua gracilis Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This grassland alliance has been described from the western Great Plains, on foothill toeslopes on the eastern side of the Continental Divide in Montana and on high-elevation ridges in intermountain basins in north-central Colorado. Sites are relatively dry and occur on moderate to steep slopes with southerly to westerly exposures. Soils are lithic, often calcareous, gravelly loams and clay loams, derived from a variety of parent materials. Surface rock is important in some stands. Vegetation included in this alliance is characterized by a relatively sparse herbaceous layer that is codominated by the cool-season, medium-tall bunchgrass Pseudoroegneria spicata and the warm-season, shortgrass Bouteloua gracilis. The dwarf-shrub Artemisia frigida is often present. Other associated species may include Heterotheca villosa, Koeleria macrantha, Opuntia polyacantha, Phlox hoodii, Poa secunda, and Sphaeralcea coccinea. Northern stands may be codominated by Hesperostipa comata (= Stipa comata), and southern stands may have high cover of Achnatherum hymenoides (= Oryzopsis hymenoides). The shrubs Artemisia tridentata ssp. wyomingensis and Ericameria parryi (= Chrysothamnus parryi) may be occasionally present. Diagnostic of this grassland alliance is the codominance of Pseudoroegneria spicata and Bouteloua gracilis.  Accession Code: VB.CC.22193.PSEUDOROEGNERIA Plot-observations of this Community Concept: 0
