Name: Pinus ponderosa / Pascopyrum smithii Woodland Reference: Western Ecology Working Group of... Description: This ponderosa pine woodland type is found in the northwestern Great Plains and Black Hills foothills of the United States. At Wind Cave National Park in the Black Hills of South Dakota, stands are best developed on gentle to moderately steep slopes of all aspects except south. On northerly aspects, and in stands with greater tree cover, the more mesophytic graminoids have greater cover. Drier sites may contain a more xerophytic mix of species. At Wind Cave National Park, stands are characterized by a somewhat-open canopy of Pinus ponderosa, with coverage in the 25-50% range. A subcanopy of smaller pines may be present. The shrub stratum is usually sparse, with Amorpha canescens, Artemisia frigida, Rhus trilobata, and Toxicodendron pubescens the most frequently found species. Herbaceous cover is typically greater than 75% and graminoid-dominated. Species composition is quite variable. On northerly aspects and in stands with greater tree cover, the more mesophytic graminoids have greater cover, such as Hesperostipa spartea (= Stipa spartea), Nassella viridula, Elymus canadensis, Muhlenbergia racemosa, Pascopyrum smithii, and Sporobolus heterolepis. Schizachyrium scoparium, Carex inops ssp. heliophila and Hesperostipa comata are the common dominants on drier sites. Piptatherum micranthum (= Oryzopsis micrantha) is dominant at some sites.  Accession Code: VB.CC.22002.PINUSPONDEROSAP Plot-observations of this Community Concept: 0
