Transition T1A
Absence of disturbance and natural regeneration over time, may be coupled with excessive grazing pressure
Mechanism
Heavy abusive grazing, no brush management, no fires, and brush invasion has led to a shift from the Mid/Tallgrass Savannah State to Oak/Juniper State.
Mechanism
Brush management, pasture planting, range planting, and crop cultivation are some practices that shift from the Savannah State to a Converted Land State.
Mechanism
The Oak/Juniper State can be restored to the Mid/Tallgrass Savannah State through the application of prescribed grazing, prescribed burning, and brush management conservation practices.

Mechanism
With the implementation of various conservation practices including brush management, pasture planting, range planting, and crop cultivation, the Oak/Juniper State can shift to the Converted Land State.
Transition T3A
Absence of disturbance and natural regeneration over time, may be coupled with excessive grazing pressure
Mechanism
The Converted Land State can be reverted back to the Oak/Juniper State due to abusive grazing, no fires, no brush management, invasion of brush species, no pasture/cropland management, land abandonment/idle, and no pest management.
