Description
Reference state is a forest community dominated by sugar maple (Acer saccharum) and white ash. Depending on history of disturbance, two community phases can be distinguished largely by differences in dominance of tree species and community age structure.

Description
Following disturbances described in Transition T1A a wide range of forest community phases may come into temporary existence, the three most common ones are described here.
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
Abandonment of agricultural practices and allowing natural vegetation to colonize the site or apply artificial afforestation.
Mechanism
A period of some 70-100 years without major stand disturbance, especially fire, leads to decreased presence, through natural mortality, of early successional species and the dominance of shade tolerant sugar maple with less tolerant associates of red oak and white ash, returning the community to Reference State.
Mechanism
Removal of forest cover, tilling and application of other agricultural techniques to grow agricultural crops.
