Name:
Thuja occidentalis - Betula alleghaniensis Forest
Reference:
Midwestern Ecology Working Group...
Description:
This upland white-cedar - hardwood forest type is found in the northern Great Lakes region of the United States and Canada, and portions of central Canada. Stands occur on poorly drained lowland soils, occasionally bordering on wet, organic soils. The soil is typically moderately acidic, sandy clay with a thin litter layer. The canopy of this community is dominated by Thuja occidentalis and a variety of hardwoods, most typically Betula alleghaniensis, Betula papyrifera, and Populus tremuloides, but occasionally Acer rubrum, Acer saccharum and Fraxinus nigra. Associated conifers include Abies balsamea, Picea glauca, and, rarely, Tsuga canadensis. The understory usually contains a well-developed shrub/sapling layer, including Abies balsamea, Acer spicatum, Corylus cornuta, Diervilla lonicera, Linnaea borealis, Ribes triste, Rubus pubescens, and Taxus canadensis. Herbaceous species include Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Clintonia borealis, Coptis trifolia, Cornus canadensis, Dryopteris carthusiana, Galium triflorum, Gymnocarpium dryopteris, Lycopodium spp., Maianthemum canadense, Mitella nuda, Onoclea sensibilis, and Trientalis borealis. Moss species include Pleurozium schreberi, Rhytidiadelphus triquetrus, and others. Diagnostic features include the mixed dominance of Thuja occidentalis and hardwoods, particularly Betula alleghaniensis, in an essentially upland site type.
