Nearly half of the original wetlands in the U.S. have been lost. Many were drained and converted to agriculture production. The beneficial functions and values that wetlands provide to society are now universally recognized. The Food Security Act of 1985 (’85 Farm Bill), as amended, required persons who wanted to participate in USDA programs and receive benefits to be in compliance with the Highly Erodible Lands (HEL) and Wetland Conservation provisions of the Law. “Swampbuster” provided an incentive for landowners to not drain/convert wetlands for commodity crop production.
