Description
Reference state is a forest community dominated by mixed conifers, principally balsam fir (Abies balsamea) and white spruce (Picea glauca) and scattered individuals of northern white cedar (Thuja occidentalis), or white pine (Pinus strobus), often with admixture of several deciduous species, typically trembling aspen (Populus tremuloides ), paper birch (Betula papyrifera), or red maple (Acer rubrum). Depending on history of disturbance, two community phases can be distinguished largely by differences in dominance of tree species and community age structure.
Submodel
Description
The deciduous forest phase may be pure or mixed aspen and paper birch. Often red maple is an associate in this community phase. A shrub layer of beaked hazelnut is not uncommon on these sites.
Submodel
Mechanism
Stand replacing disturbance that may include blow-down or ice storm, but must include fire to eliminate slash and competing vegetation and expose mineral soil to allow aspen and/or paper birch to colonize the site by seed. Alternatively, if the disrupted reference state community included aspen trees, the species may become re-established by vegetative means, which typically is more successful than colonization by seed.
