Name: Pinus edulis - (Juniperus osteosperma) / Bouteloua gracilis Woodland Reference: Western Ecology Working Group of... Description: This woodland association is known from mountains and mesas in the southern Colorado Plateau, Mogollon Rim and extending north into southern Utah and probably western Colorado. Elevations normally range from 1700-2400 m (5575-7875 feet). Sites are variable but generally are relatively dry and rocky. Stands occur on flat to moderate slopes along drainages and on mesatops, on gentle to moderate (10-40%) rocky slopes of foothills, and at the base of cinder cones. The substrates are variable and range from deep, fine- or coarse-textured soils derived from cinder to finer-textured soils derived from sandstone, shale and limestone. The vegetation is characterized by an open to moderately dense tree canopy (10-65% cover) codominated by <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> trees that are between 1 and 5 m tall. <i>Pinus edulis</i> may be present with relatively small cover in some stands. <i>Juniperus deppeana</i> may replace <i>Juniperus osteosperma</i> in southern stands. Other species of <i>Juniperus</i>, such as <i>Juniperus scopulorum</i>, may be present in higher elevation stands. Shrub cover is sparse (<10% cover). If <i>Quercus gambelii</i> is present, it has less than 5% cover. Other associated shrubs may be present in low cover, such as <i>Cercocarpus montanus, Chrysothamnus viscidiflorus, Ephedra viridis, Ericameria nauseosa, Eriogonum microthecum, Rhus trilobata</i>, or <i>Yucca</i> spp. The herbaceous layer is typically moderately dense and is dominated by the warm-season, perennial short grass <i>Bouteloua gracilis</i>. Associated graminoids include <i>Aristida</i> spp., <i>Achnatherum hymenoides (= Oryzopsis hymenoides), Bouteloua curtipendula, Elymus elymoides, Koeleria macrantha, Hesperostipa comata (= Stipa comata), Hesperostipa neomexicana (= Stipa neomexicana)</i>, and <i>Pleuraphis jamesii (= Hilaria jamesii)</i>. <i>Muhlenbergia montana</i> is absent or scarce (<1% cover). Forb cover is typically low but may be moderately diverse.  Accession Code: VB.CC.32967.CEGL000778 Plot-observations of this Community Concept: 0
