Submodel
Description
Unknown new site. This plant community has gone over the threshold to a new site. Site potential has been reduced. Significant soil loss has occurred. Infiltration has been reduced and run-off has become more rapid. This state has developed due to continued improper grazing management and/or frequent fires. This site will not return to State 1 or 2 through accelerated practices because of significant soil loss.
Submodel
Mechanism
State 1 Phase C to State 2, Phase B. Develops through improper grazing management. This site has crossed the threshold. It is usually uneconomical to return this community to State1 through accelerated practices.
State 1 Phase B to State 2 Phase A. Develops through improper grazing management with no fire. This site has crossed the threshold. It is usually uneconomical to return this community to State1 through accelerated practices.
Mechanism
State 2 to unknown site. Excessive soil loss and changes in the hydrologic cycle caused by improper grazing management and/or frequent fire cause this state to cross the threshold and retrogress to a new site with reduced potential. It is usually uneconomical to return this community to State1 through accelerated practices.
