Name: Pinus ponderosa / Prunus virginiana Forest Reference: Midwestern Ecology Working Group... Description: This community type is found in the Black Hills and northeastern Rocky Mountains, and western Great Plains escarpments of the United States. It occurs on gentle to moderate (2-40%), north-facing slopes and close to streams. A few stands are on rolling uplands. The soils are sandy loam or loam. This forest community has a closed canopy of Pinus ponderosa. Seedlings and saplings of Crataegus succulenta and Fraxinus pennsylvanica are often scattered in the understory. These species may grow to be mature trees near streams. There are two shrub layers in this community. The most prominent layer is approximately 1 m tall and dominated by Prunus virginiana. Amelanchier alnifolia also contributes significantly to this layer. The lower shrub layer is approximately 50 cm tall. It is dominated by Mahonia repens with lesser amounts of Juniperus communis, Ribes missouriense, Rosa woodsii, Symphoricarpos albus, and Toxicodendron rydbergii. The diversity of forbs is moderate, but most of the coverage of the herbaceous layer is provided by graminoids. Apocynum androsaemifolium, Elymus caninus, Carex inops ssp. heliophila, Galium boreale, Schizachne purpurascens, and Maianthemum stellatum are typical components of the herbaceous layer.  Accession Code: VB.CC.18610.PINUSPONDEROSAP Plot-observations of this Community Concept: 0
