Program overview

Wisconsin Wetland Conservation Trust — Learn


The Wisconsin Wetland Conservation Trust (WWCT) is a statewide wetland mitigation in-lieu fee (ILF) program sponsored and administered by the Wisconsin DNR. Operational since November 2014, the WWCT allows permittees or exempt project proponents with unavoidable wetland impacts to mitigate through the purchase of credits. The program is available in all watersheds in Wisconsin.

Credit fees are used to restore, establish, enhance, or preserve wetlands within the same watershed as the impact. The WWCT operates in 12 Service Areas, or major watersheds, across Wisconsin. Fees from several scattered wetland impacts are used for wetland restoration projects to provide for lost ecological values and functions. Read our annual reports for a summary of program activity.


The WWCT has prioritized restoration need according to Service Area by using tools such as the Wetlands and Watersheds Explorer and writing these priorities into the Compensation Planning Framework of the Program Instrument.

The WWCT also tracks credit sales by HUC8 watersheds to ensure consistency with requirements in 2019 Wisconsin Act 59 and provide transparency in mitigation decision-making.

The WWCT issues a Request for Proposals (RFP) with available funding and credit needs for new projects  on a quarterly schedule (December 1, March 1, June 1, October 1). The WWCT has 14 total projects with seven in the development and review phase and seven beginning monitoring for performance standards in 2020.

Regulatory Structure

The WWCT is regulated by an Interagency Review Team (IRT) made up of the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency. In 2014, the IRT approved the WWCT Instrument, the guiding document for all policies and procedures for the program. The Wisconsin DNR sponsors the program, coordinating credit sales, mitigation projects, and all administration of the program.
