Name: Pinus edulis - Juniperus spp. / Cercocarpus montanus Woodland Reference: Western Ecology Working Group of... Description: This broadly defined woodland association is common on the Colorado Plateau, occurring on dry foothills and mesas from north-central New Mexico and southern Colorado west to the Mogollon Rim of Arizona, and in extreme northwestern Colorado and adjacent Utah. Elevations range from 1830-2440 m. Stands occur on gentle to moderately steep slopes on all aspects. The soils are variable, but generally shallow, poorly developed and skeletal, ranging from clayey marl to sandy loam. Rock outcrop and bare soil are common. Parent materials include sandstone and shale. The vegetation is characterized by an open to moderately dense tree canopy (10-60% cover) codominated by Pinus edulis and Juniperus spp. The species of Juniperus varies with geography and elevation. Juniperus monosperma is common in north-central New Mexico and southern Colorado. Juniperus deppeana is common in southern New Mexico, and Juniperus osteosperma is common from northwestern New Mexico west into Arizona and north into western Colorado and Utah. Juniperus scopulorum is more common in higher elevation stands. Cercocarpus montanus dominates the moderately dense short-shrub layer (>25% cover). Other shrubs may be present including Amelanchier spp., Ephedra viridis, Gutierrezia sarothrae, Fendlera rupicola, Garrya ovata, Mahonia spp., Nolina microcarpa, Quercus gambelii, Quercus grisea, Rhus trilobata, or species of Yucca and Opuntia. Herbaceous cover is variable, ranging from sparse to moderately dense, and generally dominated by graminoids (>5% cover) with scattered forbs.  Accession Code: VB.CC.21870.PINUSEDULISJUNI Plot-observations of this Community Concept: 0
