Description:
This alliance, found in the southern boreal region, is composed of upland conifer forests. Stands in this alliance have a closed canopy which is dominated by ~Picea glauca$ and ~Abies balsamea$. There are generally other associated tree species such as ~Acer rubrum, Betula papyrifera, Picea mariana, Populus balsamifera, Populus tremuloides$, and ~Thuja occidentalis$ (on more mesic sites). A significant tall-shrub/sapling layer is also characteristic, with a less extensive, but still present, short-shrub layer. The former is usually dominated by ~Abies balsamea, Acer spicatum, Amelanchier$ spp., ~Corylus cornuta$, and ~Picea mariana$, while the most abundant species in the latter are typically ~Diervilla lonicera, Rosa acicularis$, and ~Rubus pubescens$. The herbaceous layer is often quite poor and includes species such as ~Anemone quinquefolia, Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Cornus canadensis, Clintonia borealis, Maianthemum canadense, Mitella nuda$, and ~Trientalis borealis$. Feathermosses are common to abundant on the forest floor (Sims et al. 1989, Zoladeski et al. 1995). ^Stands of this alliance are found on level to gently sloping dry-mesic to mesic sites. The soils are generally moderately well-drained, deep, loams, sands, or silts. Organic content is low (LaRoi 1967, Sims et al. 1989).
