Target ecosystem state
Select a state
Description
This state represents the disturbance regime prior to Euro-American settlement and the absence of invasive plant species. Typical fire return interval is approximately 1 to 2 years.
Submodel
Description
This state represents fire-exclusion with minimal ground disturbance. The impact of invasive species is small.
Submodel
Description
This state represents post-cultivation conditions that may best fit within land-use models in future work. Weedy invasive species are usually present and competitive. Fire is excluded. Hydrology is not altered by draining or filling.
Submodel
Mechanism
This pathway represents cessation of fire over a period long enough that shade-intolerant perennials in the reference community do not recover dominance following removal of woody vegetation. Soil develop a litter layer consisting mainly of leaves.
Mechanism
This pathway represents tillage to the extent that root systems and seed banks of native plants are depleted. Invasive plants are introduced.
Mechanism
This pathway represents tree removal, prescribed fire or mowing, seeding prairie species, and weed control.
Mechanism
This pathway represents tillage to the extent that root systems and seed banks of native plants are depleted. Soil litter layer is removed. Invasive plants are introduced.
Mechanism
This pathway represents tree removal (if needed), weed control, seeding prairie species, and prescribed fire or mowing.
