Resilience management
State 2 to unknown site. Results from permanently losing the water table in the soil profile through down cutting of the stream channel. The site crosses the threshold and retrogresses to a new site with reduced potential due to significant loss of available soil moisture from the lowered water table. It occurs with continued improper grazing management or repeated significant runoff events. It is not feasible to return this site to State 1 or State 2 without raising the water table.
Submodel
Mechanism
State 1 Phase 1.1 or 1.2 to State 2. Develops through permanently lowering the late growing season water table to 40 to 60 inches.This can occur with continued improper grazing management. It may also occur with proper grazing on the site, but channel erosion may continue if poor off-site conditions cause frequent and/or severe flooding. This site has crossed the threshold. It is not feasible to return this site to State 1 without raising the water table.
