Description:
This mixed mountain shrubland occurs in southern Utah and western Colorado. Stands occur in canyons, or on mesas, benches, plateaus, ridges, foothills scarps and mountains. Elevation ranges from 1525 to 2700 m (5000-8860 feet). Slopes are gentle to steep (1-100%) and may be oriented to any aspect. Soil are generally deep, well-developed and are derived from a variety of sources, including sandstones, shales and metamorphic rocks. The vegetation is characterized by a sparse to dense (10-100+% cover) tall-shrub layer (2-5 m tall) codominated by <i>Quercus gambelii</i> and <i>Amelanchier utahensis</i>. Common shrub associates include <i>Artemisia tridentata</i> and <i>Symphoricarpos oreophilus</i>. <i>Cercocarpus montanus</i> is absent or poorly represented (<5% cover). Other shrubs and dwarf-shrubs present with low cover may include <i>Chrysothamnus viscidiflorus, Ephedra viridis, Gutierrezia sarothrae, Mahonia repens, Opuntia</i> spp., <i>Purshia tridentata</i>, and <i>Prunus virginiana</i>. Graminoids, such as <i>Pascopyrum smithii, Achnatherum hymenoides, Carex geyeri, Hesperostipa comata</i>, or <i>Poa fendleriana</i>, dominate the sparse herbaceous layer (<10% total cover). Common forbs include <i>Achillea millefolium, Artemisia ludoviciana, Allium acuminatum, Comandra umbellata, Erigeron speciosus, Lathyrus lanszwertii, Balsamorhiza sagittata, Packera multilobata, Phlox austromontana, Thalictrum fendleri</i>, or <i>Vicia americana</i>. Occasionally, scattered individual trees are present in the overstory, including <i>Pinus edulis, Pseudotsuga menziesii</i>, or <i>Juniperus osteosperma</i>.
