CEGL000982 Quercus turbinella - Coleogyne ramosissima Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sonoran Scrub Oak - Blackbrush Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This scrub oak shrubland association is currently described from Grand Canyon National Park in Arizona. More survey and classification work are needed to fully characterize this type. It occurs on sideslopes and terraces in at 1200 to 1700 m (3925-5500 feet) elevation, and is typically found on gentle slopes (5-8°) with eastern exposures. Soils are well- to rapidly-drained silty or sandy loams that typically lie above sandstone or limestone. Total shrub cover averages 20-30% and is codominated by the short shrubs Quercus turbinella and Coleogyne ramosissima. The canopy tree Pinus edulis and the subcanopy tree Juniperus osteosperma are occasionally found. The short-shrub layer also occasionally includes Amelanchier utahensis, Ephedra aspera, and Yucca baccata. Agave utahensis is invariably present in a sparse dwarf-shrub stratum. Aristida purpurea consistently occurs in an extremely weak graminoid layer. Scattered forbs do exist, but their cover is so low that they hardly constitute a layer.

Floristics: Total shrub cover averages 20-30% and is codominated by the short shrubs Quercus turbinella and Coleogyne ramosissima. The canopy tree Pinus edulis and the subcanopy tree Juniperus osteosperma are occasionally found. The short-shrub layer also occasionally includes Amelanchier utahensis, Ephedra aspera (= Ephedra fasciculata), and Yucca baccata. Agave utahensis is invariably present in a sparse dwarf-shrub stratum. Aristida purpurea consistently occurs in an extremely weak graminoid layer. Scattered forbs do exist, but their cover is so low that they hardly constitute a layer.
