CEGL000598 Populus tremuloides / Quercus gambelii / Symphoricarpos oreophilus Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen / Gambel Oak / Mountain Snowberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This deciduous forest is known from central New Mexico, the southwestern Colorado Plateau and southern Rocky Mountains where it occurs along drainages on plateaus and in draws on mountain slopes. Elevations range from 2240-2538 m. Stands occur along intermittent streams on moderately steep to steep slopes with southwestern to northwestern aspects. Soils tend to be relatively shallow, finer-textured loams derived from alluvium and residuum from volcanic or sedimentary rocks. Litter covers much of the ground surface. The vegetation is characterized by a moderately dense to dense tree canopy dominated by Populus tremuloides. Quercus gambelii dominates the tall-shrub layer (>10% cover) and may be present in the tree canopy. Symphoricarpos oreophilus or Symphoricarpos rotundifolius form the short-shrub layer (>10% cover) with several other shrub species. The herbaceous layer is generally sparse, but may be moderately dense, and is usually a diverse mixture of grasses and forbs.

Floristics: The association is characterized by a moderately dense to dense tree canopy dominated by Populus tremuloides. Quercus gambelii dominates the tall-shrub layer (>10% cover) and may be present in the tree canopy. Symphoricarpos oreophilus or Symphoricarpos rotundifolius form the short-shrub layer (>10% cover) with several other shrub species. Additional tall, short, and dwarf-shrubs provide low to moderate cover and include Amelanchier alnifolia, Mahonia repens, Paxistima myrsinites, Prunus virginiana, Pseudotsuga menziesii seedlings, and Rosa woodsii. The herbaceous layer is generally sparse, but may be moderately dense, and is usually a diverse mixture of grasses and forbs. Forb species may include Achillea millefolium, Galium boreale, Geranium sp., Heracleum maximum, Lathyrus lanszwertii, Ligusticum porteri, Maianthemum stellatum, Pedicularis procera, Senecio eremophilus, Solidago velutina, Thalictrum fendleri, and Vicia americana. Common graminoids include Bromus anomalus, Bromus porteri, Carex geyeri, Festuca thurberi, and the introduced perennial Poa pratensis.
