Name: Populus tremuloides / Calamagrostis rubescens Forest Reference: Western Ecology Working Group of... Description: This is a relatively common deciduous forest known from Washington, Idaho, Montana, Wyoming, and Utah. It is described from over 100 plots. It occurs on benches and slopes irrespective of slope steepness or aspect. It occurs primarily below 2440 m (8000 feet) in elevation, ranging from 1829 to 2440 m (6000-8000 feet). Soils are primarily derived from sandstone. The vegetation of this major association is comparatively simple both in structure and in composition. Most of the time, <i>Populus tremuloides</i> is the only tree in the overstory. Conifers, if present, are incidental and can include <i>Pinus contorta, Picea engelmannii</i>, and <i>Pseudotsuga menziesii</i>. Shrubs such as <i>Symphoricarpos oreophilus, Rosa woodsii, Amelanchier alnifolia</i>, and <i>Juniperus communis</i> may be present but never form a distinct layer. The herbaceous undergrowth is dominated by <i>Calamagrostis rubescens</i>. Other graminoids include <i>Elymus trachycaulus (= Agropyron trachycaulum), Bromus carinatus, Elymus glaucus</i>, and <i>Poa pratensis</i>. Commonly found forbs include <i>Geranium viscosissimum, Lupinus argenteus, Osmorhiza berteroi (= Osmorhiza chilensis), Fragaria vesca</i>, and <i>Achillea millefolium var. occidentalis (= Achillea lanulosa)</i>.  Accession Code: VB.CC.32788.CEGL000575 Plot-observations of this Community Concept: 0
