Reference:
NatureServe Biotics 2019
Description:
This uncommon tall-shrub association occurs in scattered small patches on rock outcrops and landslide deposits on the slopes of mesas and canyons. Sites are moderately steep to steep and occur between 1700 and 2550 m elevation. The unvegetated surface has moderate to high cover of litter, bedrock, rocks, and bare soil. The underlying geology includes Tertiary volcanic rocks, metamorphic and granitic rocks, and Quaternary landslide deposits. Total vegetation cover ranges from 60 to 90%. The tall-shrub canopy is typically 1-2 m tall and characteristically consists of <i>Quercus gambelii</i> with 5 to 100% cover, <i>Amelanchier utahensis</i> with 1 to 15% cover, and <i>Holodiscus dumosus</i> with 1 to 50% cover. Other shrubs that contribute to the total cover can include <i>Acer negundo, Artemisia tridentata ssp. wyomingensis, Mahonia repens, Prunus virginiana, Philadelphus microphyllus, Quercus gambelii, Rhus trilobata, Ribes cereum</i>, and <i>Symphoricarpos rotundifolius</i>. The herbaceous layer provides up to 15% total cover and may include <i>Achnatherum hymenoides, Carex geyeri, Elymus trachycaulus, Poa fendleriana, Artemisia frigida, Artemisia ludoviciana, Galium boreale, Geranium</i> sp., <i>Hymenopappus filifolius, Maianthemum stellatum, Solidago velutina</i>, and <i>Toxicodendron rydbergii</i>.
