Description
In absence of stand-leveling disturbances the Reference State Community oscillates between two easily definable community phases, a mature, or late successional, community phase and a rejuvenated community phase.
Dominant plant species
pine (Pinus), tree
oak (Quercus), tree
quaking aspen (Populus tremuloides), tree
paper birch (Betula papyrifera), tree
Submodel
Description
Post-logging state may consist of considerable diversity of pioneer and mid-successional community phases. Here we are describing four, most commonly found under current conditions.
Dominant plant species
pine (Pinus), tree

Description
This State is characterized by livestock grazing on site. Management inputs are variable but may include woody species removal, brush control, and seeding of forage species.
Submodel
Mechanism
Clear cutting with initial control of competing vegetation, or stand-replacing fire prepare the site for occupancy by shade intolerant species. This may occur through natural regeneration or by planting.
Mechanism
A period of some 70-100 years without major stand disturbance leads to decreased presence, through natural mortality, of early successional species and the dominance of relatively shade tolerant white pine and sub-canopy of red maple.
Mechanism
The site is cleared for agricultural production.
Mechanism
Removal of livestock grazing.
Mechanism
The site is transitioned to crop production.
