Name: Populus tremuloides - Pinus contorta / Symphoricarpos oreophilus Forest
Reference: Western Ecology Working Group of...
Description: This mixed deciduous-evergreen association appears to be adapted to a wide range of environments. It occurs at elevations ranging from 1740 to 2990 m (5700-9800 feet) and does not appear confined by slope, exposure or soil parent materials. <i>Populus tremuloides</i> forms the dominant overstory canopy with an average cover of 55%. <i>Pinus contorta</i> is the only prominent conifer in the tree layer, always present with 22% average cover. Other conifers with less cover include <i>Pseudotsuga menziesii, Picea pungens</i>, and <i>Abies lasiocarpa</i>. Seedlings of both aspen and lodgepole are also usually present. The low-shrub layer is dominated by <i>Symphoricarpos oreophilus</i> with 10-30% cover. Other shrubs present include <i>Shepherdia canadensis, Rosa woodsii</i>, or <i>Paxistima myrsinites</i>. Tall shrubs such as <i>Amelanchier alnifolia</i> and <i>Prunus virginiana</i> may be present but in low abundance, never forming a distinct layer. The herbaceous undergrowth is generally dominated by graminoids such as <i>Calamagrostis rubescens</i> and <i>Carex geyeri</i>. A variety of forbs are usually present; most frequent are <i>Thalictrum fendleri, Lupinus argenteus, Geranium viscosissimum, Osmorhiza berteroi (= Osmorhiza chilensis)</i>, and <i>Chamerion angustifolium</i>. The undergrowth may not be abundant but is usually quite diverse.
