Name: Pinus edulis - Juniperus spp. / Artemisia tridentata (ssp. wyomingensis, ssp. vaseyana) Woodland Reference: Western Ecology Working Group of... Description: This broadly defined woodland association is common in the Colorado Plateau but also occurs on dry foothills and mesas from north-central New Mexico and southern Colorado west to the eastern Mojave Desert, in extreme northwestern Colorado and adjacent Utah. Elevations range from 1465 to 2500 m (4800-8200 feet). Stands occur most often on flat to gentle slopes on all aspects. The soils are generally poorly developed, moderately deep to deep, well-drained to rapidly drained loams and sands. Ground cover is variable; bare soil is common, but bedrock, litter, and large or small rocks can also be abundant on some sites. Parent material includes sandstone and shale. The vegetation is characterized by a typically open tree canopy (10-30% cover but ranges up to 50% cover) that is codominated by <i>Pinus edulis</i> and <i>Juniperus</i> spp. The species of <i>Juniperus</i> varies with geography and elevation. <i>Juniperus monosperma</i> is common in north-central New Mexico and southern Colorado. <i>Juniperus osteosperma</i> is common from northwestern New Mexico west and north into Arizona and Utah. <i>Juniperus scopulorum</i> is more common in higher elevation stands. <i>Artemisia tridentata</i> (either <i>ssp. vaseyana</i> or <i>ssp. wyomingensis</i> depending on location) strongly dominates the sparse to moderately dense short-shrub layer (10-35% cover). <i>Purshia stansburiana</i> is typically absent or scarce. Other shrubs present may include <i>Amelanchier utahensis, Arctostaphylos patula, Cercocarpus montanus, Ephedra viridis, Gutierrezia sarothrae, Quercus gambelii</i> (typically <5% cover), or species of <i>Yucca</i> and <i>Opuntia</i>. Herbaceous cover is variable but generally sparse and dominated by graminoids (<5% cover) with scattered forbs.  Accession Code: VB.CC.31992.CEGL000776 Plot-observations of this Community Concept: 0
