Description
This State represents what is believed to exist prior to European settlement In Reference, this site is dominated by cool- and warm-season season grasses, and various shrub species. Grazing or the lack of grazing, fire, excessive haying, erosion, and invasion of non-native cool-season grasses are major drivers in this State.
Submodel
Description
Heavy, long-term animal or machinery impacts have altered soil site stability, hydrologic function, and the biotic integrity of the site. Erosion can down-cut the channel to the point that the site no longer receives additional moisture from overflow. This State is resistant to change and a restoration pathway may not be feasible.
Submodel
Mechanism
Frequent and severe defoliation, heavy disturbance such as livestock feed, excessive haying, invasion of non-native cool-season grasses, and erosion will transition the Reference State (1.0) to the Degraded State (2.0).
