Name: Quercus macrocarpa - Populus tremuloides / Corylus spp. Woodland
Reference: Midwestern Ecology Working Group...
Description: This bur oak - aspen woodland is found primarily in the aspen parkland tallgrass region of the United States (Minnesota) and adjacent Canada (Manitoba), with outliers in northwest Ontario. Stands occur on dry to mesic sites, particularly where there were firebreaks, such as occur on hilly moraines, glacial lake beach ridges, or steep terraces along rivers. Soils are loamy, and often deep and well-developed. Structurally, these stands are intermediate between closed-canopy forests and a more open, widely scattered savanna structure. Dominants in the tree canopy include <i>Quercus macrocarpa</i> and <i>Populus tremuloides</i>, the latter increasing in the absence of fire. Occasional associates include <i>Fraxinus pennsylvanica, Betula papyrifera</i>, and <i>Ulmus americana</i>. The shrub layer can be quite dense. Dominant species include <i>Amelanchier</i> spp. (especially <i>Amelanchier alnifolia</i>), <i>Cornus foemina, Corylus americana, Corylus cornuta, Rosa</i> spp., <i>Rubus</i> spp., <i>Symphoricarpos occidentalis</i>, and <i>Viburnum</i> spp. (including <i>Viburnum opulus var. americanum (= Viburnum trilobum)</i>). The herbaceous layer can contain prairie species, but these occur in small openings in the tree or shrub layer. More typically, the herb layer is composed of species able to tolerate the more dense shade cast by the woody layers, including <i>Aralia nudicaulis, Carex pensylvanica, Maianthemum canadense, Sanicula marilandica</i>, and <i>Thalictrum dioicum</i>.
