Flooding occurs annually, but high-energy events which rearrange channels, scour, or deposit gravelly alluvium occur less often and are the primary form of disturbance. Invasive plant species are insignificant in this state.
Submodel
1.1. Deciduous Forest Black Cottonwood, Red Alder, Shrubs, and Forbs
1.2. Deciduous Shrub, Field Willows, Grasses, and Forbs
This state represents post-cultivation conditions with flood control that may best fit within land-use models in future work. Weedy invasive species are usually present and competitive. Hydrology is not altered by draining or filling.
Submodel
2.1. Cropland or Pastureland
2.2. Prairie or Shrub Field, Himalayan Blackberry, Pasture Grasses, and Annual Grasses
2.3. Deciduous Forest Black Cottonwood, Alder, Ash, Deciduous Shrubs, Himalayan Blackberry, and Weedy Forbs
This pathway represents 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.
This pathway represents a high energy flood that destroys the plant community and either exposes or deposits sandy and gravelly material. This pathway requires a migrating stream channel to return to the site.
