Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Greenleaf Manzanita - Gambel Oak - (Utah Serviceberry) Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This tall shrubland is known only from southern Utah, from Zion and Bryce Canyon national parks. This shrubland occurs on gentle to steep slopes of mesas and high-elevation plateaus, from 1829 to 2109 m (6000-6919 feet). It occurs at all aspects on mostly well-drained sandy loam soil. Stands of this association are common and widespread in Zion National Park and less common in Bryce Canyon National Park. Arctostaphylos patula and Quercus gambelii codominate, each with cover ranging from 5 to 50%. Other shrubs occur with less than 10% cover and include Mahonia fremontii, Mahonia repens, Cercocarpus montanus, Ceanothus martinii, Amelanchier utahensis, Symphoricarpos oreophilus, Quercus turbinella, and Ericameria nauseosa. The herbaceous layer provides sparse cover and includes grasses, such as Poa fendleriana, Bouteloua gracilis, Leymus salinus, and Sporobolus cryptandrus, and forbs Maianthemum stellatum, Physaria chambersii, and Stenotus armerioides. A few emergent trees are often present near this community and include Pinus edulis, Juniperus scopulorum, and Juniperus osteosperma, both as large trees and as saplings.
