-
Transition T1A
Absence of disturbance and natural regeneration over time, excessive grazing pressure, may be coupled with prolong drought
More details -
Restoration pathway R2A
Removal of woody canopy, appropriate rest from defoliation, and release from drought
More details -
No transition or restoration pathway between the selected states has been described
Target ecosystem state

Mechanism
Heavy continuous grazing, lack of fire, and drought will transition this site into a Shrubland State (2). The site is characterized by greater than 40 percent woody canopy cover.
Mechanism
Prescribed grazing and brush management are required to restore the community back to a Grassland State (1). Removal of woody species below 30 percent allows more light and nutrients to herbaceous species. Reducing grazing pressure will allow plants to regain vigor and re-establish.
