Name: Pseudotsuga menziesii / Osmorhiza berteroi Forest Reference: Steele, R., R. D. Pfister, R. A.... Description: 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 <i>Pseudotsuga menziesii</i> is the only conifer present; however, <i>Populus tremuloides, Acer grandidentatum</i>, and sometimes <i>Pinus contorta, Pinus flexilis</i> or <i>Abies lasiocarpa</i> 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 <i>Prunus virginiana, Symphoricarpos oreophilus, Shepherdia canadensis, Mahonia repens</i>, and <i>Amelanchier alnifolia</i>. <i>Osmorhiza berteroi</i> and sometimes <i>Osmorhiza depauperata</i> dominates the forb layer. Other herbaceous species include <i>Maianthemum racemosum (= Smilacina racemosa), Viola nuttallii, Helianthella uniflora, Calamagrostis rubescens</i>, and <i>Elymus glaucus</i>.  Accession Code: VB.CC.31451.CEGL000445 Plot-observations of this Community Concept: 0
