Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Two-needle Pinyon - Utah Juniper / Cliff Fendlerbush Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland association is known from the Northern Colorado Plateau at Canyon de Chelly National Monument in northeastern Arizona and Canyonlands National Park in southwestern Utah. It occurs in canyons, ridges and talus slopes from 1637-2146 m (5369-7041 feet) elevation. Stands occur on gentle to moderately steep slopes (8-25%) on all aspects. The soils are generally shallow and rocky, and loamy sand to sandy loam in texture. The vegetation is characterized by an open to moderately dense tree canopy (10-50% cover) codominated by Pinus edulis and Juniperus osteosperma. Juniperus monosperma may be present in some stands. Fendlera rupicola dominates or codominates the open to moderately dense tall-shrub layer. Other shrubs may be present, including Artemisia ludoviciana, Artemisia tridentata, Gutierrezia microcephala, Gutierrezia sarothrae, Opuntia phaeacantha, Opuntia polyacantha var. polyacantha, Cylindropuntia whipplei, and Purshia stansburiana. Quercus gambelii may be present with <5% cover. Herbaceous cover is variable, ranging from sparse to moderately dense, but is generally dominated the perennial graminoid Bouteloua gracilis (<5% cover) with scattered perennial forbs.
