Name: A.417
Reference: EcoArt 2002
Description: This alliance, found in the western Great Lakes region, is characterized by mesic, upland forests. The canopy is codominated by two species, ~Thuja occidentalis$ and ~Betula alleghaniensis$. Associated trees include ~Acer saccharum, Abies balsamea, Betula papyrifera$, and ~Tsuga canadensis$ (in the eastern portion of this alliance's range). In Wisconsin, ~Acer saccharum$ may be relatively more common and ~Betula alleghaniensis$ less so. The understory usually contains a well-developed shrub layer. ~Acer spicatum$ and ~Taxus canadensis$ are the most abundant species in this layer. Herbaceous species include ~Clintonia borealis, Dryopteris campyloptera, Lycopodium$ spp., ~Maianthemum canadense$, and ~Trientalis borealis$. ^Stands of this alliance occur on poorly drained lowland soils. The soil in northern Wisconsin was reported as moderately acidic sandy clay with a thin litter layer (Beals and Cottam 1960), although Eyre (1980) stated that ~Thuja occidentalis$ grew best on neutral to slightly alkaline sites.
