Name: Pinus edulis / Arctostaphylos pungens Woodland Reference: Western Ecology Working Group of... Description: These open woodlands have been described from canyon sides, terraces, benches and elevated plains in central and north-central Arizona and may extend into southwestern New Mexico. Elevations range from 1520-2440 m. Sites are flat to steep slopes often with southern aspects. Substrates are rocky soil derived from sandstone or limestone. Stands have a total vegetation cover of 20-60%. They are patchy with an open (>5% cover) conifer tree canopy 3-8 m tall that is codominated by Pinus edulis and Juniperus osteosperma. The short-shrub layer has over 25% cover and is often a dense and diverse thicket dominated by the evergreen sclerophyllous shrubs Arctostaphylos pungens and Quercus turbinella. Other shrub species often include Garrya flavescens, Ephedra viridis, Yucca baccata, Artemisia tridentata, Amelanchier spp., Cercocarpus montanus, Cercocarpus intricatus, Mahonia fremontii, Purshia stansburiana, Yucca baccata, Rhus trilobata, and Glossopetalon spinescens. The herbaceous layer is typically sparse if present and is composed of scattered forbs and graminoids. The dominance of Arctostaphylos pungens often with Quercus turbinella in the dense, short-shrub layer, and the sparse herbaceous cover separates this association from other Pinus edulis - Juniperus osteosperma woodlands. Small treeless thickets are included in this association.  Accession Code: VB.CC.22128.PINUSEDULISARCT Plot-observations of this Community Concept: 0
