Hierarchy Level: Association
Type Concept: This association has only been described from Zion National Park, Utah. Addition global information will be added as it becomes available. Pinus monophylla and Juniperus osteosperma dominate the canopy layer with 20-40% cover. The shrub layer cover is less than 15%. Common shrubs that may occur are Quercus turbinella, Amelanchier utahensis, Shepherdia rotundifolia, Ephedra viridis, Ericameria nauseosa, and the dwarf-shrub Gutierrezia sarothrae. Hesperostipa comata is dominant in the herbaceous layer with 10-50% cover. Other graminoids that may codominate or sub-dominate are Poa fendleriana, Bouteloua gracilis, Bouteloua eriopoda, Aristida purpurea, Bromus tectorum, and Muhlenbergia pungens. This association occurs on flat plateaus and steep colluvial slopes with commonly southern to southwestern aspects. Soil texture is sandy. Elevation ranges from 1220 to 1768 m (4000-5800 feet).
