Name: Pinus ponderosa / Arctostaphylos uva-ursi Woodland Reference: Midwestern Ecology Working Group... Description: This ponderosa pine / kinnikinnick woodland community is found in the Black Hills region and Rocky Mountain Front Range. Elevation ranges from 1540 to 2775 m (4250-9100 feet) in the Black Hills and 1920 to 2700 m (6300-8890 feet) in the Rocky Mountains. Stands occur in warm, dry habitats on all aspects and slopes, although it is most prevalent on gentle, south-facing midslopes with sandy loam or clay loam soils. The tree canopy is dominated by <i>Pinus ponderosa</i>; occasional associates include <i>Pseudotsuga menziesii</i> or <i>Populus tremuloides</i>, with <i>Quercus macrocarpa</i> common in the Black Hills. The dwarf-shrub <i>Arctostaphylos uva-ursi</i> is characteristic and abundant in this association. Other shrubs occur at lower densities and can include <i>Symphoricarpos albus, Mahonia repens, Rosa</i> spp., <i>Juniperus communis, Purshia tridentata, Ribes cereum, Physocarpus monogynus</i>, and <i>Spiraea betulifolia</i> in the Black Hills, and <i>Quercus gambelii</i> in the southern Rocky Mountains. Composition of the herbaceous layer is variable and not well-developed where shrub cover is high. Graminoids are more prevalent, especially <i>Muhlenbergia montana, Leucopoa kingii, Carex geyeri, Carex rossii</i>, and <i>Festuca arizonica</i>, with <i>Carex inops ssp. heliophila</i> occurring in the southern Rocky Mountains and <i>Oryzopsis asperifolia</i> in the Black Hills. Forbs are usually present with low cover and can include <i>Arnica cordifolia, Lupinus argenteus, Geranium caespitosum, Potentilla fissa, Achillea millefolium</i>, and <i>Lathyrus ochroleucus</i>.  Accession Code: VB.CC.36850.CEGL000844 Plot-observations of this Community Concept: 0
