Description
Tree species on these sites are mostly fire adapted and it is likely that the intensity and frequency of fires controlled the plant community composition in presettlement time. It is likely though that the same species, perhaps with the exception of Jack pine, could maintain themselves on these sites. White pine would have likely dominated these sites in the advanced reference state. Red maple would be less likely with more frequent or higher intensity fire.
Submodel
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
This pathway relies on natural succession with only minor disturbances for 70+ years to allow full canopy development. Particularly this pathway is allowing for the regeneration and growth of a White pine super canopy and greater development of the understory species present.
Mechanism
Abandonment of agricultural practices and allowing natural vegetation to colonize the site or apply artificial afforestation. Whether re-vegetation or planting is allowed it is likely to require over 100 years to return to the reference state via the early to mid-successional state.
