State 1
Reference State
Description
Reference state is a forest community dominated by balsam fir (Abies balsamea) and red maple (Acer rubrun). 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
Post disturbance pioneer community of aspen and paper birch with mixtures of other species from available seed sources.
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 and tilling for agricultural crop production.
Mechanism
Conifers slowly increase in abundance in the deciduous forest community.
Mechanism
Removal of forest cover and tilling for agricultural crop production.
Mechanism
Abandonment of agricultural practices and allowing natural vegetation to colonize the site or apply artificial afforestation. The time required for forest community to reach the reference state conditions may exceed 100 years. Unless understory plants are seeded naturally or artificially it may take some time before the understory is restored.
