Name: Pascopyrum smithii - Bouteloua gracilis Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This western wheatgrass - blue grama prairie was once an extensive grassland of the Southern Great Plains and Chihuahuan Desert of the United States. Stands occur within montane swales or along upland valley bottoms. It generally occurs on northerly aspects at elevations between 1900 and 2500 m (6000 and 8000 feet). Slopes are typically gentle with fine-textured and well-developed soils that are predominantly from eroded Paleozoic sandstone and limestone. Luxuriant cover that can be dominated by either Bouteloua gracilis or Pascopyrum smithii typifies this grassland. Juniperus monosperma or Pinus edulis communities usually surround this swale association. Graminoid diversity is usually low, with scattered grasses, such as Muhlenbergia repens, Koeleria macrantha and Elymus elymoides, often present. In Kansas, Bouteloua curtipendula and Buchloe dactyloides may also be present. The shrub layer is very open and moderate in diversity and generally includes Atriplex canescens and Krascheninnikovia lanata (which both occur as phases and can become dominant in disturbed areas), Opuntia phaeacantha and Opuntia imbricata. Forb diversity and cover is generally low.  Accession Code: VB.CC.21480.PASCOPYRUMSMITH Plot-observations of this Community Concept: 0
