CEGL000445 Pseudotsuga menziesii / Osmorhiza berteroi Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir / Mountain Sweet-cicely Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is known from northern Utah; southern, eastern, and central Idaho; and western Wyoming. It occurs between 1650 and 2377 m (5400-7800 feet) in elevation, on moderate to steep lower to middle slopes on northern, northeasterly and eastern aspects, generally in protected locations. Soils are often gravelly silty clay loams to sandy loams, often from sedimentary colluvial parent materials. Usually Pseudotsuga menziesii is the only conifer present; however, Populus tremuloides, Acer grandidentatum, and sometimes Pinus contorta, Pinus flexilis or Abies lasiocarpa may be present and even abundant. The undergrowth is diverse, with shrubs influenced by adjacent montane shrub communities, with species spilling into this type, but not abundant enough to form a distinct layer. Shrub species present include Prunus virginiana, Symphoricarpos oreophilus, Shepherdia canadensis, Mahonia repens, and Amelanchier alnifolia. Osmorhiza berteroi and sometimes Osmorhiza depauperata dominates the forb layer. Other herbaceous species include Maianthemum racemosum, Viola nuttallii, Helianthella uniflora, Calamagrostis rubescens, and Elymus glaucus.

Floristics: Usually Pseudotsuga menziesii is the only conifer present. Populus tremuloides, Acer grandidentatum, and sometimes Pinus contorta, Pinus flexilis or Abies lasiocarpa may be present and even abundant. The undergrowth is diverse; the shrub layer is generally influenced by adjacent montane shrub communities, with species spilling into this type but not really a part of the community. Shrub species present include Prunus virginiana, Symphoricarpos oreophilus, Shepherdia canadensis, Mahonia repens, and Amelanchier alnifolia. Osmorhiza berteroi and sometimes Osmorhiza depauperata dominate the forb layer. Other herbaceous species include Maianthemum racemosum (= Smilacina racemosa), Viola nuttallii, Helianthella uniflora, Calamagrostis rubescens, and Elymus glaucus.
