Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen / Needle-and-Thread Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is described from approximately 16 plots ranging geographically from the Centennial Mountains in Idaho to the Markagunt Plateau in southern Utah. It is most common on Dixie National Forest in southern Utah. The association occurs on gentle slopes of all exposures at 1980 m (6500 feet) and 2590 to 2900 m (8500-9500 feet) elevation, respectively, in the northern and southern extent of its range. Stands are dominated by Populus tremuloides. A few, dispersed conifers may be present. Juniperus communis, Artemisia tridentata, Mahonia repens, and Symphoricarpos oreophilus may occur with low abundance in the open understory shrub canopy. Understory grass and forb growth is usually depauperate.
