Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen - Subalpine Fir / Russet Buffaloberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This quaking aspen forest association occurs in the Rocky Mountains of Colorado, Utah, Idaho and Wyoming. This description is based on information solely from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This association is documented from a stream terrace at 3098 m elevation. Terrain is gently sloping with north-facing slopes. Soils are somewhat poorly drained sandy loams. Ground cover is dominated by litter and duff, but can have significant cover of wood. This forested association is dominated by a moderately open canopy of Populus tremuloides and Picea engelmannii, with scattered Pseudotsuga menziesii. Conifers are also present in the shrub layer, which is dominated by Shepherdia canadensis (30%). The dwarf-shrub layer is dominated by Vaccinium myrtillus with 60% cover. Forbs and graminoids are present in only trace amounts.
