Name: Pinus ponderosa Dry-Mesic Black Hills Forest & Woodland Alliance Reference: NatureServe Biotics 2019 Description: This forest and woodland alliance occurs on dry to mesic sites at montane and foothill elevations in the Black Hills. Stands are primarily dominated by <i>Pinus ponderosa</i> but may include a sparse to relatively dense subcanopy of <i>Juniperus scopulorum</i>. The understory is variable. Shrubs may form a sparse to moderately layer or be absent. Characteristic species can include <i>Arctostaphylos uva-ursi, Artemisia tridentata ssp. wyomingensis, Juniperus communis, Juniperus horizontalis, Mahonia repens, Rhus trilobata, Spiraea betulifolia</i>, and <i>Symphoricarpos albus</i>. The herbaceous understory can range from a sparse to moderately dense layer. Common species include <i>Carex siccata, Danthonia spicata, Galium boreale, Nassella viridula, Oryzopsis asperifolia</i>, and <i>Schizachne purpurascens</i>. This alliance has been found on flat to moderately sloping topography (2-24%) below 1280 m (4200 feet) elevation on sandy loam, silt loam to clay loam soils often derived from weathered sandstone, limestone, and scoria. Stands occur on all aspects. At montane elevations, it often occurs on warmer, drier south-facing slopes, but at lower elevation, it is generally found on cooler northerly aspects.  Accession Code: urn:lsid:vegbank.org:commConcept:38749-{759CFC2A-4A7A-4FF6-9E47-DCD5F4921060} Plot-observations of this Community Concept: 0
