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 fires contribute to the shift from the Grassland Hardwood State to the Hardwood Woodland State.
Transition T1B
Extensive soil disturbance followed by seeding
Mechanism
Brush management, pasture planting, range planting, and crop cultivation speeds up the shift from the Grassland Hardwood State to the Converted Land State.
Restoration pathway R2A
Reintroduction of historic disturbance return intervals
Mechanism
Prescribed grazing, brush management, IPT, range planting, and prescribed burning are various conservation practices to revert back to Grassland Hardwood State from the Hardwood Woodland State.
