CEGL002967 Juniperus scopulorum - Quercus gambelii Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Rocky Mountain Juniper - Gambel Oak Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland association is known from the southern Colorado Plateau in northeastern Arizona and southwestern Utah at elevations ranging from 1647-2238 m (5400-7343 feet). Stands occur in gently sloping drainage bottomlands and swales and occasionally hillsides. Soils include sandy loams, and ground litter ranges from 15-50% cover. The vegetation is characterized by an open to relatively dense tree canopy (20-80% cover) codominated by Juniperus scopulorum and Quercus gambelii. Juniperus osteosperma may also be present to common in the tree canopy of some stands, and occasional emergent Pinus ponderosa trees may be present with <5% cover. Pinus edulis and Pinus monophylla are typically absent but may occur with low cover (<5%). In some stands the oaks may form more of a tall-shrub layer than a tree canopy. Otherwise, the shrub layer is typically sparse with scattered Artemisia tridentata, Cercocarpus montanus, Chrysothamnus depressus, Fendlera rupicola, Gutierrezia microcephala, Purshia tridentata, and Yucca angustissima. The herbaceous layer is variable with sparse to moderate cover (5-50%) and low to high diversity of species. Common species may include Antennaria parvifolia and Pascopyrum smithii.

Floristics: This association is characterized by an open to relatively dense tree canopy (20-80% cover) codominated by Juniperus scopulorum and Quercus gambelii. Juniperus osteosperma may also be present to common in the tree canopy of some stands, and occasional emergent Pinus ponderosa trees may be present with <5% cover. Pinus edulis and Pinus monophylla (western stands) are typically absent but may occur with low cover (<5%). In some stands the oaks may form more of a tall-shrub layer than a tree canopy. Otherwise, the shrub layer is typically sparse with scattered Artemisia tridentata, Cercocarpus montanus, Chrysothamnus depressus, Fendlera rupicola, Gutierrezia microcephala, Purshia tridentata, and Yucca angustissima. The herbaceous layer is variable with sparse to moderate cover (5-50%) and low to high diversity of species. Common species may include Antennaria parvifolia and Pascopyrum smithii.

Environmental Description: This woodland association is known from the southern Colorado Plateau in northeastern Arizona and southwestern Utah at elevations ranging from 1647-2238 m (5400-7343 feet). Stands occur in gently sloping drainage bottomlands and swales and occasionally hillsides. Soils include sandy loams, and ground litter ranges from 15-50% cover.
Geographic Range: This association has currently only been described from Canyon de Chelly National Monument and Zion National Park in northeastern Arizona and southwestern Utah, and in Curecanti National Recreation Area in western Colorado. It will likely be found elsewhere in the southern Colorado Plateau.
