Name: Pinus edulis - Juniperus osteosperma / Cercocarpus intricatus Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs on dry sandstone ridgetops, mesa edges, outcrops, colluvial slopes, slickrock hills, benches and knolls at moderate elevations of 1484 to 2470 m (4870-8100 feet) on the Colorado Plateau and in extreme northwestern Colorado, adjacent Utah, and possibly Wyoming. South and southwest aspects are common, and slopes can be variable in steepness. Exposed bedrock and large rock may cover over 50% of the stand, with vegetation growing in the cracks. These sandstone-derived soils are generally poorly developed, coarse-textured and skeletal. Bare soil is common. The vegetation is characterized by a short (2-10 m), open tree canopy (10-25% cover) codominated by <i>Pinus edulis</i> and <i>Juniperus osteosperma</i>, and by the dominance of <i>Cercocarpus intricatus</i> in the relatively sparse short-shrub layer (5-25% cover). <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> vary in cover between 1 and 15%, though higher covers are possible. The shrubs <i>Amelanchier utahensis, Arctostaphylos patula, Gutierrezia sarothrae, Mahonia fremontii, Quercus gambelii</i>, or <i>Yucca</i> spp. are often present in many stands. Herbaceous cover is sparse (<5% cover) and is composed of scattered forbs and grasses such as species of <i>Cryptantha, Penstemon</i>, and <i>Opuntia, Achnatherum hymenoides (= Oryzopsis hymenoides), Bouteloua gracilis, Elymus elymoides, Pleuraphis jamesii</i>, and <i>Poa fendleriana</i>.  Accession Code: VB.CC.32965.CEGL000779 Plot-observations of this Community Concept: 0
