Submodel
Transition T1A
Absence of disturbance and natural regeneration over time, may be coupled with excessive grazing pressure
Mechanism
Heavy abusive grazing, no brush management, and no fire have contributed to the shift from the Hardwood Grassland State to the Hardwood Woodland State.
Transition T1B
Extensive soil disturbance followed by seeding
Mechanism
Brush management, pasture planting, range planting, and crop cultivation conservation practices can ease the transition from the Hardwood Grassland State to the Converted Land State.
Restoration pathway R2A
Reintroduction of historic disturbance return intervals
Mechanism
The Hardwood Woodland State can revert back to the Hardwood Grassland State through the application of brush management, prescribed grazing, IPT, range planting, and prescribed burning conservation practices.
