Converted wetland

A converted wetland is one that has been drained, dredged, filled, leveled, or otherwise altered for the production of an agricultural commodity. The definition is part of The Highly Erodible Land Conservation and Wetland Conservation Compliance provisions (Swampbuster) introduced in the 1985 Farm Bill (also known as The Food Security Act of 1985). The provisions aim to reduce soil loss on erosion-prone lands and to protect wetlands for the multiple benefits they provide.
