Name: Pinus ponderosa / Prunus virginiana Forest Reference: NatureServe Biotics 2019 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 <i>Pinus ponderosa</i>. Seedlings and saplings of <i>Crataegus succulenta</i> and <i>Fraxinus pennsylvanica</i> 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 <i>Prunus virginiana</i>. <i>Amelanchier alnifolia</i> also contributes significantly to this layer. The lower shrub layer is approximately 50 cm tall. It is dominated by <i>Mahonia repens</i> with lesser amounts of <i>Juniperus communis, Ribes missouriense, Rosa woodsii, Symphoricarpos albus</i>, and <i>Toxicodendron rydbergii</i>. The diversity of forbs is moderate, but most of the coverage of the herbaceous layer is provided by graminoids. <i>Apocynum androsaemifolium, Elymus caninus, Carex inops ssp. heliophila, Galium boreale, Schizachne purpurascens</i>, and <i>Maianthemum stellatum</i> are typical components of the herbaceous layer.  Accession Code: urn:lsid:vegbank.org:commConcept:29101-{C91EEA36-A527-4C72-B46D-199D637280DD} Plot-observations of this Community Concept: 1
