Description
The reference plant community is a mixed hardwood floodplain forest. The dominant species in the canopy are American sycamore, eastern cottonwood, silver maple, boxelder, red maple, green ash, sweetgum, and swamp white oak. An earlier successional phase of this site is comprised largely of young cottonwoods, willows, and dogwoods. The understory consists of water-tolerant herbaceous species.
Submodel
Description
This state is characterized by non-native species which, if left unchecked, can alter the plant composition of the natural community.
Submodel
Description
Most common agricultural row crop on these sites is a corn-soybean rotation. Other grains may be planted depending on management goals. A small percentage of the historic acres are used for forage and pasture. Most sites have had hydrological modifications installed such as tiling and ditching.

Mechanism
This transition is driven by disturbance (clearning, oak removal, hydrological modification, etc.) and the invasion of non-native plants into the natural system. Left uncontrolled, the ecological viability and species diversity of the site will likely be compromised. Management control of brush and weeds is recommended.
Mechanism
Clearing of forest. Brush removal. Site preparation and plantings. Management activities will depend upon goals and objectives of the landowner. Landowners should seek out assistance in evaluating wetland issues potentially associated with these sites to insure compliance with federal wetland regulations.
Mechanism
Management activities to reduce and control invasive plant species. Planting of desired species. Long-term forest management activities.

Mechanism
A site that is abandoned will revert to a mix of fast growing trees. Species will depend upon seed sources, but common to these disturbed sites are maples, ashes, and poplar. Disturbances such as selective harvest, clearing, and grazing may result in the introduction of non-native vegetation.
