Description: This upland sub-boreal forest alliance occurs from the western Great Lakes region to Manitoba. The canopy is moderately closed to closed and composed of a mix of northern coniferous and deciduous trees. Typical dominants are ~Abies balsamea, Betula papyrifera, Picea glauca$, and ~Populus tremuloides$. Other common trees that may be abundant in some stands are ~Acer rubrum, Picea mariana, Pinus strobus, Populus balsamifera$, and ~Thuja occidentalis$. The sapling/shrub layer is usually moderately well-developed. ~Abies balsamea$ and ~Populus$ spp. are abundant saplings in most stands and the shrubs ~Acer spicatum, Corylus cornuta, Diervilla lonicera, Rubus pubescens$, and ~Sorbus americana$. ~Taxus canadensis$ may be found in stands near Lake Superior on islands such as Isle Royale and the Apostle Islands. The herbaceous layer is variable. It can be depauperate or species-rich. Species found in this stratum include ~Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Symphyotrichum ciliolatum (= Aster ciliolatus), Cornus canadensis, Clintonia borealis, Galium triflorum, Maianthemum canadense, Mitella nuda$, and ~Trientalis borealis$. ~Lycopodium$ spp. and ~Sphagnum$ spp. are abundant in some stands. ^Stands of this alliance are found on upland sites with moist to dry-mesic, deep, mineral soils. Loams, clays, and silts are the most common surface soil types. The sites are generally relatively flat but can be on gentle to moderate slopes.
