Transition T1A
Absence of disturbance and natural regeneration over time, may be coupled with excessive grazing pressure
Mechanism
Heavy abusive grazing, absence of fire, and lack of brush management transition this site to a Shrubland State (2).
Restoration pathway R2A
Reintroduction of historic disturbance return intervals
Mechanism
Prescribed grazing, prescribed burning, brush management, and possibly range planting are required to restore the Shrubland State (2) back to the reference state. Depending on previous land history, erosion and soil fertility may be so low that a full restoration is unattainable.
