Name: Populus tremuloides / Corylus cornuta Forest Reference: Western Ecology Working Group of... Description: This upland forest community is found on gently sloping or rolling topography in the northwestern Great Plains and the Rocky Mountain and Black Hills ranges of the United States and southern Canada. Stands may be found on a variety of aspects, often more northerly. The soils are well-developed and deep. They can be derived from a variety of sources, including limestone, quartzite, schist, Tertiary volcanics, and glacial till. This deciduous forest community can have a moderately closed to closed canopy. <i>Populus tremuloides</i> is the dominant tree, and <i>Betula papyrifera</i> can be codominant. Scattered <i>Quercus macrocarpa, Fraxinus pennsylvanica</i> and, in the Black Hills, <i>Picea glauca</i> or <i>Pinus ponderosa</i> can also be found. There is a conspicuous understory of shrubs and forbs; few graminoids achieve prominence. The shrub layer is 1-2 m tall and dominated by <i>Corylus cornuta</i>. Other species found with it include <i>Amelanchier alnifolia, Mahonia repens, Prunus virginiana, Symphoricarpos</i> spp., and <i>Rubus idaeus</i>. In the western part of its range <i>Spiraea betulifolia</i> is also common. The herbaceous layer has <i>Aralia nudicaulis, Lathyrus ochroleucus, Maianthemum canadense, Galium triflorum, Maianthemum stellatum, Viola</i> spp., and <i>Sanicula marilandica</i>. In the eastern part of its range this community can have significant amounts of <i>Carex pensylvanica</i>.  Accession Code: VB.CC.33018.CEGL000583 Plot-observations of this Community Concept: 0
