Name: Quercus turbinella - Juniperus osteosperma Shrubland Reference: Western Ecology Working Group of... Description: This scrub oak shrubland association is currently described from Grand Canyon National Park and Grand Canyon-Parashant National Monument in Arizona. It is also reported from Nevada and Wyoming and possibly Utah. More survey and classification work are needed to fully characterize this type. It typically occurs on moderate to steep (15-40°) mid and upper sideslopes at 1075 to 1825 m (3475-6025 feet) elevation, across all aspects. Soils are rapidly-drained sandy or silty loams derived from sandstone or limestone. This predominantly shrub-dominated community supports an open and scattered tree layer. <i>Juniperus osteosperma</i> dominates and characterizes this stratum but typically assumes a stunted and shrublike physiognomy. Other tall shrubs are essentially absent. Along with <i>Juniperus osteosperma</i>, the short shrub <i>Quercus turbinella</i> codominates this association. <i>Rhus trilobata, Yucca baccata</i>, and <i>Ephedra fasciculata</i> also frequently occur in the short-shrub layer, while up to 25 different species can sporadically occur here. <i>Gutierrezia sarothrae</i> and occasionally <i>Thamnosma montana</i> occur in the dwarf-shrub layer. Graminoid cover is relatively sparse; <i>Achnatherum speciosum</i> occurs in most stands, while <i>Aristida purpurea</i> and <i>Poa fendleriana</i> sometimes occur as well. Forb composition varies considerably among stands, and approximately 60 different species can occur in the forb understory.  Accession Code: VB.CC.32764.CEGL000981 Plot-observations of this Community Concept: 0
