The DNR will help determine if the proposed project needs an approved flood plain development permit. Floodplain forests are distinguished from northern hardwood swamps by their vertically fluctuating water levels and lateral movement of floodwaters rather than a relatively stable supply of groundwater, thus have a lower proportion of peat (muck) soils due floods removing fine organic matter and soil drying out by mid-late summer allowing remaining organic matter to decompose.

Residential development on the bluffs above the floodplain has increased rapidly in recent years, and the conservation implications include the inadvertent introduction of invasive species, loss or disturbance of the forested blufflands adjoining the floodplain, and generally higher levels of human use. Opportunities for management are limited here but include significant sites along the Lower St. Croix River, and some parts of the middle stretches of the Wisconsin River and its tributaries.
