Transition T1A
This transition develops through lack of fire and improper grazing management. The site has crossed the threshold. It is not economically feasible to move this state back towards state 1.
More details -
Transition T1B
From community phase 1.3 or 1.5 this transition develops with no fire and improper grazing management. The site has crossed the threshold. It is not economically feasible to move this state back towards state 1.
More details -
Transition T2A
This transition is a result of brush management, pest management or prescribed fire prior to range seeding.
More details -
Transition T2B
This transition is a result of excessive soil loss and changes in the hydrologic cycle caused by improper grazing management or frequent fire. This state retrogresses to a new site with reduced potential. The site has crossed the threshold and is not economically feasible to move the state back towards state 1.
More details -
Transition T3A
This transition develops with fire.
More details -
Transition T3B
This transition develops from brush management, fire, or pest management in preparation for a range seeding.
More details -
Transition T3C
This transition is a result of improper grazing management and lack of fire. This state retrogresses to a new site with reduced potential due to significant soil loss and changes in hydrology. It has crossed the threshold, and it will not go back to state 1.
