Description
On this site, this vegetation community ranges from an open overstory to a nearly closed canopy. Fire helps to establish and maintain a more open canopy, but, on this moist site, some locations with a frequent fire return interval maintain a nearly closed canopy of mixed pine and oak. This vegetation community on this site is exceptionally rare today, due mostly to landuse conversion to agriculture.
(Peat and Allard, 1993; Schafale and Weakley, 1990)
Description
Mixed hardwood forests are closed canopy forests dominated by deciduous hardwoods. These forests tend to occur at locations protected from fire. These forests are typically uneven aged with regeneration establishing in canopy gaps. Pines and shade tolerant hardwoods tend to occur in areas that have experienced disturbance.
(FNAI, 2010; Peat and Allard, 1993; Schafale and Weakley, 1990)
Submodel
Description
Restoration efforts might include revegetation and reintroduction of periodic fire. There is increased interest in restoration of longleaf pine and it's associated vegetation communities including the application of prescribed and controlled fire. However, it is unclear whether or not the full historical range of fire behavior and fire seasonality can be restored on the modern landscape, and the limited scope of modern fire application may impact full restoration to historical conditions.
Mechanism
Lack of fire, or a fire return interval that exceeds 10 years on a consistent basis for a long period of time.
