CEGL000543 Populus tremuloides - Pseudotsuga menziesii / Amelanchier alnifolia Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen - Douglas-fir / Saskatoon Serviceberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This mixed deciduous-evergreen forest is uncommon but wide-ranging, occurring from the southern Rocky Mountains and Colorado Plateau to the Yellowstone Plateau of eastern Idaho and northwestern Wyoming. It occurs between 1700 and 2695 m (5600-8840 feet) elevation. Stands are usually on moderate to steep slopes of various aspects, and soils are generally derived from sedimentary parent materials. The vegetative structure of this association is complex. It consists of multi-layers of trees, shrubs and herbs. The characteristic features are the moderately dense to dense mixed canopy of Populus tremuloides and Pseudotsuga menziesii in the overstory with 25-75% relative canopy cover of each and a tall-shrub stratum dominated by one or a combination of the following shrubs: Amelanchier alnifolia, Prunus virginiana, or Acer grandidentatum. A distinct low-shrub layer is also present and is composed of Symphoricarpos spp., Rosa woodsii, Mahonia repens, Spiraea betulifolia, and Paxistima myrsinites. The herbaceous layer is an abundant mix of graminoids and forbs. Common species include Elymus spp., Thalictrum spp., Osmorhiza spp., and Geranium viscosissimum. Occasionally Calamagrostis rubescens, Carex geyeri, or Arnica cordifolia may be abundant.

Floristics: The vegetative structure of this association is complex. It consists of multi-layers of trees, shrubs and herbs. The characteristic features are the moderately dense to dense mixed canopy of Populus tremuloides and Pseudotsuga menziesii in the overstory with 25-75% relative canopy cover of each and a tall-shrub stratum dominated by one or a combination of Amelanchier alnifolia, Prunus virginiana, or Acer grandidentatum. A distinct low-shrub layer is also present and is composed of Symphoricarpos spp., Rosa woodsii, Lonicera utahensis, Mahonia repens, Spiraea betulifolia, and Paxistima myrsinites. The sparse to moderately dense herbaceous layer is a mixture of graminoids and forbs. Common species include Bromus porteri, Elymus trachycaulus, Eucephalus engelmannii, Galium boreale, Geranium viscosissimum, Lathyrus lanszwertii, Ligusticum porteri, Maianthemum racemosum, Osmorhiza spp., and Thalictrum spp. Occasionally Calamagrostis rubescens, Elymus glaucus, Carex geyeri, or Arnica cordifolia may be abundant (Mueggler 1988). Introduced perennial grass Poa pratensis is reported from some stands.

Environmental Description: This mixed deciduous-evergreen forest is uncommon but wide-ranging, occurring from the La Sal Mountains in southern Utah and the southern Rocky Mountains of western Colorado to the Yellowstone Plateau of eastern Idaho and northwestern Wyoming. It occurs between 1700 and 2695 m (5600-8840 feet) elevation. Stands are usually on moderate to steep slopes of various aspects, and soils are generally derived from sedimentary parent materials but include metamorphic granites (Mueggler 1988). Substrates are frequently well-drained, sandy loam soils.
Geographic Range: This association is known from the southern and central Rocky Mountains and occurs from western Colorado and the Colorado Plateau to northern Utah, eastern Idaho and northwestern Wyoming.
