Submodel
Description
This plant community is dominated by annuals and some perennial forbs. There may be a variety of invasive forbs and some noxious plants may have invaded the site. Some soil loss has occurred. The community has developed due to continued improper grazing management and frequent fire. This site has crossed the threshold. It is economically impractical to return this state to State 1 with accelerated practices.
Description
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 or frequent fires. It is economically impractical to return this state to State 1 with accelerated practices.
Mechanism
State 1 Phase B and C to State 2. Develops through improper grazing management and frequent fire. This site has crossed the threshold. It is economically impractical to return this state to State 1 with accelerated practices
Mechanism
Excessive soil loss and changes in the hydrologic cycle caused by improper
grazing management or frequent fires cause this state to cross the threshold and retrogress to a new site with reduced potential. It is economically impractical to return this state to State 1 with accelerated practices
