This state represents the disturbance regime prior to Euro-American settlement and the absence of invasive plant species. Natural fire regime was mixed severity. Typical fire return interval is approximately 35 to 100 years.
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.

Mechanism
This pathway represents tree and stump removal and tillage to the extent that root systems and seed banks of native plants are depleted. Soil litter layer is removed. Invasive plant species are introduced.
