CEGL000836 Pinus monophylla - Juniperus osteosperma / Prunus virginiana Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Singleleaf Pinyon - Utah Juniper / Chokecherry Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association has been described from a small region in south-central Idaho at the southern end of the Albion Mountains, Cassia County, Idaho. It has also been reported from Nevada. Little information is available regarding the structure and composition of this association. Two evergreen needle-leaved trees dominate the canopy, Pinus monophylla and Juniperus osteosperma, with total cover of 30-70%. Pinus monophylla is always present, while the Juniperus is present with varying frequency. There is a tall-shrub layer dominated by the broad-leaved deciduous Prunus virginiana. The herbaceous understory is not described, but probably includes perennial bunchgrasses and forbs. This association occurs in a mountainous region that is part of the northern extension of the Basin and Range Province into Idaho. This region is characterized by a series of parallel mountain ranges oriented in a north-south direction. The intervening valleys are wide and floored with sediments from ancient Lake Bonneville. The southern Albion Mountains, where this association is found, are a complex of four gneiss domes, aligned along a north-south axis. Landforms associated with these domes include steep-sided ridges, and erosional features such as tors and linear rock ridges enclosing narrow canyons. Rock types include granodiorite, gneiss with bodies of schist, some quartzite, and lenses, pods and sheets of amphibolite.

Environmental Description: This association occurs in a mountainous region that is part of the northern extension of the Basin and Range Province into Idaho. This region is characterized by a series of parallel mountain ranges oriented in a north-south direction. The intervening valleys are wide and floored with sediments from ancient Lake Bonneville. The southern Albion Mountains, where this association is found, are a complex of four gneiss domes, aligned along a north-south axis. Landforms associated with these domes include steep-sided ridges, and erosional features such as tors and linear rock ridges enclosing narrow canyons. Rock types include granodiorite, gneiss with bodies of schist, some quartzite, and lenses, pods and sheets of amphibolite. The climate of the region is characterized as semi-arid, with warm summers and cold winters. Average annual precipitation is 28 cm (11 inches), and shows a peak during April through June, when more than 30% of the annual total is received. The remainder is distributed evenly throughout the year. More specific information for this association is not available. Elevations range from approximately 1830 to 2255 m (6000-7400 feet). Soils are sandy to gravelly and well-drained. In arid to semi-arid regions, Prunus virginiana typically occurs along ravines and watercourses, and in more mesic sites. From this it can be inferred that this association may occupy the narrow canyons and small valleys where the flow of water is channeled when draining off the surrounding rocky topography.
Geographic Range: This association has been described from a small region in south-central Idaho at the southern end of the Albion Mountains, Cassia County, Idaho. Part of the region is contained in the City of Rocks National Reserve and the City of Rocks RNA. It has also been reported from Nevada.
