Description
Reference state is a forest community dominated by red maple (Acer rubrum) with groups of balsam fir (Abies balsamea). 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
Pure, or mixed, aspen – paper birch community replaces the reference state community. If seed source is present, red maple and young cohorts of balsam fir readily becomes member of this community.
Submodel
Mechanism
Stand replacing disturbance that must include fire to create conditions for aspen and paper birch to colonize the site.
Mechanism
Removal of forest cover by whatever means, followed by tilling for agricultural crop production. Establishment of agricultural crops, hay, or pasture following the disturbance.
Mechanism
Deciduous forest community slowly ages out and is invaded by conifers, especially Balsam fir. Other species such as Red maple and Green or Black ash may begin to take hold as well as Aspen and Birch trees die and canopy openings develop.
Mechanism
Removal of forest cover by whatever means, followed by tilling for agricultural crop production. Establishment of agricultural crops, hay, or pasture following the disturbance.
Mechanism
Cessation of agricultural practices leads to natural reforestation, or site is replanted. Initial species is seed source dependent unless planted. Most likely initial species are Aspen and Red Maple.
