Name: Pinus ponderosa / Purshia stansburiana Woodland Reference: Western Ecology Working Group of... Description: These woodlands occur in central Arizona near the southern limit of <i>Pinus ponderosa</i>, and may also occur in central New Mexico north into Colorado, Utah, Wyoming and Idaho. Elevation ranges from 2240-2440 m. Sites often have a rough and rocky topography, but include flat and undulating terrain. Substrates are rocky, shallow, sandy textured soils typically derived from limestone, but also the association may also occur on sandstone and igneous parent materials. Stands have an open (>10% cover) tree canopy that is dominated by the needle-leaved evergreen tree, <i>Pinus ponderosa</i>. Other tree species present may include <i>Pinus edulis, Juniperus osteosperma, Juniperus scopulorum, Quercus gambelii</i>, and occasionally <i>Pseudotsuga menziesii</i>. The short-shrub layer has 5-25% cover with the deciduous shrub <i>Purshia stansburiana (= Purshia mexicana var. stansburiana)</i> being diagnostic of this type. Other common shrub species include <i>Artemisia nova, Purshia tridentata, Rhus trilobata, Quercus gambelii, Mahonia repens, Yucca baccata</i> and <i>Yucca glauca</i>. The relatively sparse (5-25% cover) herbaceous layer is dominated by graminoids such as <i>Muhlenbergia montana, Bouteloua</i> spp., <i>Aristida arizonica, Poa fendleriana</i>, and <i>Elymus elymoides</i> with scattered forbs such as <i>Heterotheca villosa, Solidago</i> spp., <i>Eriogonum racemosum</i>, and <i>Tradescantia pinetorum</i>.  Accession Code: VB.CC.33243.CEGL000854 Plot-observations of this Community Concept: 0
