Name:
Thuja occidentalis - Betula alleghaniensis Forest
Reference:
NatureServe Biotics 2019
Description:
This upland white-cedar - hardwood forest is found in the northern Great Lakes region of the United States and portions of central Canada, and occasionally eastward into northern New England. Stands occur on well-drained to somewhat poorly drained upland soils. The soil is typically moderately acidic sandy clay with a thin litter layer. The canopy of this community is dominated by <i>Thuja occidentalis</i> and a variety of hardwoods, most typically <i>Betula alleghaniensis, Betula papyrifera</i>, and <i>Populus tremuloides</i>, but occasionally <i>Acer rubrum</i> and <i>Acer saccharum</i>. Associated conifers include <i>Abies balsamea, Picea glauca</i>, and, rarely, <i>Tsuga canadensis</i>. The understory usually contains a well-developed shrub/sapling layer, including <i>Abies balsamea, Acer spicatum, Corylus cornuta, Diervilla lonicera, Linnaea borealis, Ribes triste, Rubus pubescens</i>, and <i>Taxus canadensis</i>. Herbaceous species include <i>Aralia nudicaulis, Eurybia macrophylla, Clintonia borealis, Coptis trifolia, Cornus canadensis, Dryopteris carthusiana, Galium triflorum, Gymnocarpium dryopteris, Lycopodium</i> spp., <i>Maianthemum canadense, Mitella nuda, Onoclea sensibilis</i>, and <i>Trientalis borealis</i>. Moss species include <i>Pleurozium schreberi, Rhytidiadelphus triquetrus</i>, and others. Diagnostic features include the mixed dominance of <i>Thuja occidentalis</i> and hardwoods, particularly <i>Betula alleghaniensis</i>, in an essentially upland site type.
