Name: Pseudoroegneria spicata - Bouteloua gracilis Grassland Reference: NatureServe Biotics 2019 Description: This bluebunch wheatgrass grassland type is found in the western Great Plains and at low elevations in the Front Range of the Rocky Mountains. In Montana stands are found on toeslopes of the foothills and steeper slopes of valley bottoms. Soils are typically moderately deep (40-100 cm), with a variety of parent materials, and neutral in pH. Surface rock varies from 1-46%. In Montana, the vegetation is open (40-60% cover) and dominated by graminoids. <i>Pseudoroegneria spicata</i> shares dominance with <i>Hesperostipa comata</i>. <i>Bouteloua gracilis</i> is always present, but in varying amounts depending on grazing history (increasing with heavy grazing). Associated graminoids include <i>Carex duriuscula, Koeleria macrantha</i>, and <i>Poa secunda</i>. The most constant forbs include <i>Artemisia frigida</i> (sometimes classified as a shrub), <i>Phlox hoodii</i> and <i>Sphaeralcea coccinea</i>. Slightly more productive sites contain <i>Calamagrostis montanensis, Carex filifolia, Heterotheca villosa</i>, and <i>Liatris punctata</i>. Shrub cover is less than 10%. Low-growing shrubs include <i>Gutierrezia sarothrae</i> and <i>Opuntia polyacantha</i>, and taller shrubs may include <i>Ericameria nauseosa</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:30573-{9FE8F1F9-2F35-470B-93C6-86AE782C4DD4} Plot-observations of this Community Concept: 0
