Abies balsamea - Betula alleghaniensis - Populus tremuloides Subboreal Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
Stands are dominated by <i>Picea glauca</i> and <i>Abies balsamea</i> with an abundance of northern hardwoods, such as <i>Acer rubrum, Acer saccharum, Betula alleghaniensis, Populus grandidentata, Prunus serotina</i>, and <i>Tilia americana</i>, along with the boreal hardwoods <i>Populus tremuloides</i> and <i>Betula papyrifera</i>. Other conifers include <i>Pinus strobus, Thuja occidentalis</i> and, less commonly, <i>Tsuga canadensis</i>. The shrub and herb layers are variable, decreasing as the percent conifer cover increases. Common shrub species include <i>Acer spicatum, Amelanchier</i> spp., <i>Corylus cornuta, Diervilla lonicera, Lonicera canadensis</i>, and <i>Prunus virginiana</i>. The herbaceous layer is often quite poor and includes species such as <i>Anemone quinquefolia, Aralia nudicaulis, Cornus canadensis, Clintonia borealis, Eurybia macrophylla, Maianthemum canadense, Mitella nuda</i>, and <i>Trientalis borealis</i>. The moss layer ranges from discontinuous to continuous. These subboreal conifer - northern hardwood forests are found in the eastern cool temperate forest region, ranging from north-central Minnesota, Wisconsin and Michigan through central Ontario to eastern Canada. These upland forests typically occur on mesic to wet-mesic (moist) sites, most commonly level, clayey sites, and sites with high local water tables on glacial lake deposits, stagnation moraines and till plains. Wetter sites may contain <i>Alnus incana ssp. rugosa, Calamagrostis canadensis</i>, and <i>Equisetum</i> spp.
