Common (Translated Scientific) Name: Quaking Aspen / Dry-spike Sedge Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This quaking aspen forest association occurs on the Colorado Plateau and Rocky Mountains of Arizona and Colorado. This description is based on information from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This association is known from stream terraces at 2998 to 3079 m elevation. Terrain is gently sloping to steep with warmer southeast- to west-facing aspects. Soils are moderately well- to well-drained sandy loams derived from fluvial deposition. Ground cover is dominated by litter and duff, but there is a significant amount of large rock cover. These are moderately open thickets with 30-40% cover of Populus tremuloides and occasional Picea engelmannii. The short-shrub layer is dominated by Rosa woodsii and Juniperus communis. The herbaceous layer is dominated by Carex siccata with 10-30% cover. Thermopsis montana and Fragaria virginiana are the dominant forbs with 10-30% cover, although forb cover may be diverse.
