Description
Reference state is a forest community dominated by black ash. Depending on disturbance history, two community phases can be distinguished largely by differences in dominance of tree species and community age structure.
Submodel
Description
Open State consists of two main community phases. Phases are primarily driven by frequency and duration of ponding events that allow or deter establishment of woody, less tolerant species.
Submodel
Mechanism
Major stand-replacing disturbance, such as a blow-down or clear cutting. Removal of canopy causes water table to rise. Sites have more frequent and longer duration of ponding events.
Mechanism
Elimination of forest cover and the application of agricultural practices, such as artificial drainage, tilling, and planting crops.
Mechanism
Decreased frequency and duration of ponding events. Seasonal ponding where surface water drains by midsummer. Recruitment of tree species e.g. black ash on localized mounds or high points.
Mechanism
Elimination of forest cover and the application of agricultural practices, such as artificial drainage, tilling, and planting crops.
