Name: Pseudoroegneria spicata - Bouteloua gracilis Herbaceous Vegetation
Reference: Mueggler, W. F., and W. L. Stewa...
Description: This bluebunch wheatgrass grassland type is found in the western 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 (= Stipa 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 (= Carex stenophylla), Koeleria macrantha</i>, and <i>Poa secunda (= Poa sandbergii)</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 (= Chrysopsis 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 (= Chrysothamnus nauseosus)</i>.
