CEGL000546 Populus tremuloides - Pseudotsuga menziesii / Symphoricarpos oreophilus Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen - Douglas-fir / Mountain Snowberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association is known from throughout Utah, in the Yellowstone Plateau and southern Idaho. Most stands occur between 1800 and 2300 m (6000-7500 feet) elevation on gentle to steep slopes, on all aspects, primarily on soils derived from sedimentary parent materials. The tree layer is a mixture of Populus tremuloides and Pseudotsuga menziesii. Occasionally Abies lasiocarpa may be present but not abundant. The undergrowth is characterized by the low stratum of Symphoricarpos oreophilus and Rosa woodsii. The herbaceous layer is minor and includes Elymus glaucus, Calamagrostis rubescens, and Carex geyeri. Forbs present may include Arnica cordifolia, Thalictrum fendleri, Osmorhiza berteroi, and Geranium viscosissimum.

Floristics: The tree layer is a mixture of Populus tremuloides and Pseudotsuga menziesii. Occasionally Abies lasiocarpa may be present but not abundant. The undergrowth is characterized by the low stratum of Symphoricarpos oreophilus and Rosa woodsii. The herbaceous layer is minor and includes Elymus glaucus, Calamagrostis rubescens, and Carex geyeri. Forbs present may include Arnica cordifolia, Thalictrum fendleri, Osmorhiza berteroi (= Osmorhiza chilensis), and Geranium viscosissimum.
Dynamics: This association is thought to be seral to Pseudotsuga menziesii forest, but with frequent burning, this may not happen. Heavy grazing will eliminate graminoids and increase forbs. Heavy grazing by sheep will reduce the Symphoricarpos cover.
Environmental Description: Most stands occur between 1800 and 2300 m (6000-7500 feet) elevation on gentle to steep slopes, on all aspects, primarily on soils derived from sedimentary parent materials.
