Hierarchy Level: Association
Type Concept: This association is known from Grand Canyon National Park, Arizona, Lake Mead National Recreation Area, Nevada, Mojave National Preserve, California, and Zion National Park, Utah. The following description is based on occurrences at Zion National Park. Additional global information will be added as it becomes available. In this association, Juniperus osteosperma and Pinus monophylla codominate with 20-60% cover. Tree canopy height averages 5 m. Quercus turbinella, with cover of 5-50%, dominates or codominates the shrub layer with a mixture of shrubs. Other shrubs that are commonly well represented are Amelanchier utahensis, Arctostaphylos patula, and Cercocarpus montanus. Shrubs that may be present with less cover are Arctostaphylos pungens, Purshia stansburiana, Purshia tridentata, Fraxinus anomala, and Quercus gambelii. Subshrubs Gutierrezia sarothrae, Opuntia spp., and Yucca spp. are usually present with minimal cover. Herbaceous cover is minimal and inconsistent. The most commonly found forbs and graminoids are Heterotheca villosa, Arenaria fendleri, Penstemon spp., Bromus tectorum, and Poa fendleriana. This association occurs at elevations of 1220 to 1830 m (4000-6000 feet) on gentle to moderately steep colluvial slopes and hillsides throughout the western side of the park. Slope aspect is generally eastern to southern. Some sites with northern aspects have been documented in Zion Canyon. Soils are sandy loam.
