Name: Populus tremuloides - Pseudotsuga menziesii / Amelanchier alnifolia Forest
Reference: Western Ecology Working Group of...
Description: 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 <i>Populus tremuloides</i> and <i>Pseudotsuga menziesii</i> 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: <i>Amelanchier alnifolia, Prunus virginiana</i>, or <i>Acer grandidentatum</i>. A distinct low-shrub layer is also present and is comprised of <i>Symphoricarpos</i> spp., <i>Rosa woodsii, Mahonia repens, Spiraea betulifolia</i>, and <i>Paxistima myrsinites</i>. The herbaceous layer is an abundant mix of graminoids and forbs. Common species include <i>Elymus</i> spp., <i>Thalictrum</i> spp., <i>Osmorhiza</i> spp., and <i>Geranium viscosissimum</i>. Occasionally <i>Calamagrostis rubescens, Carex geyeri</i>, or <i>Arnica cordifolia</i> may be abundant.
