Description
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
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. Hydrology is not altered by draining or filling.
Submodel
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 plant species are introduced.
Mechanism
This pathway represents a hiatus from high-energy flooding and continued thickening of loamy or silty A horizons. Such horizons are usually more than 20 inches thick in soils belonging to Low Floodplain Group or Backswamp Group. On well drained soils, this transition may also be marked by the decline of willow and appearance of bigleaf maple in the canopy. This transition can result from flood control measures. It can also occur naturally as migrating stream channels move away from the site.
Mechanism
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.
Mechanism
This pathway represents a hiatus from high-energy flooding and continued thickening of loamy or silty A horizons. Such horizons are usually more than 20 inches thick in soils belonging to Low Floodplain Group or Backswamp Group. On well drained soils, this transition may be marked by the decline of willow, appearance of bigleaf maple in the canopy, or the appearance of conifer seedling and saplings. This transition can result from flood control measures. It can also occur naturally as migrating stream channels move away from the site.
