Name: Populus tremuloides - Betula papyrifera / Acer saccharum - Mixed Hardwoods Forest Reference: Midwestern Ecology Working Group... Description: This boreal aspen - birch forest type is found in the north-central United States and southern Canada on a variety of mesic upland locations. This community has been found on rich sites over clay or silt loam soils. Deciduous trees dominate the canopy and tree reproduction layers of this community. Conifers, when present, are widely scattered. Tree density is moderate to high, but substantial light penetrates the canopy due to the growth form of the dominant species, Betula papyrifera and Populus tremuloides. Other northern hardwoods may be found in the canopy but are more common in the sapling layer. These include Acer rubrum, Acer saccharum, Betula alleghaniensis, Fraxinus pennsylvanica, Ostrya virginiana, Tilia americana, and Ulmus americana (in more mesic sites). Fagus grandifolia and Tsuga canadensis become more common in eastern examples of this type. The shrub stratum is usually not well-developed due to shading from the canopy and subcanopy trees. Scattered Acer spicatum, Corylus cornuta, Diervilla lonicera and Rubus pubescens are typical shrubs. Taxus canadensis and Acer pensylvanicum are present on some sites. The herbaceous layer contains species such as Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Clintonia borealis, Maianthemum canadense, Oryzopsis asperifolia, and Streptopus lanceolatus var. longipes (= Streptopus roseus). Mosses include Dicranum flagellare, Dicranum montanum, and others.  Accession Code: VB.CC.27866.POPULUSTREMULOI Plot-observations of this Community Concept: 0
