Wetland Banking Fens Research Facility

Objective Progress / Results

To restore most of the effectively drained fields at the Fens Research Facility (Fens) to a variety of wetland types so new wetland credits can be deposited into a state wetland bank for future withdrawal as wetland mitigation credits.Wetland credit sales by the University from Fens Wetland Bank V were ongoing throughout the reporting period with 1.26 credits sold out of the total 14.26 BWSR and Army Corps approved credits available. The remaining balance as of December 31, 2014 was 13.0 credits. A Standard Operating Procedure (SOP) document was developed for future wetland credit sales. The IRRRB/UM revenue sharing document for FY13-14 for the Fens Wetland Bank IV was completed and sent to IRRRB for review and approval. Also, routine maintenance was done on the facility and equipment as the field season ended.


For about 100 years, the Fens has been used for agriculture, horticulture, fuel peat production, and peatland research. The peat soils have been intensively drained. With recent demand for wetland mitigation credits, the Fens became a candidate for peatland restoration. The Minnesota Board of Water and Soil Resources (BWSR) and the Minnesota Department of Transportation (Mn/DOT) approached NRRI about establishing numerous wetland banks at the Fens. After lengthy review, five banks are in the process of being established. A variety of wetland types are being established. New wetland credits (NWC) are being deposited into BWSR wetland banks. NWC are used for wetland replacement mitigation following loss of wetlands as a result of road construction in Northeast Minnesota.

Previous Activity / Results

Fens Wetland Bank V, a 22.12 acre wetland bank at the Fens, was solely developed by NRRI/UMD. It has been approved by Minnesota Board of Water and Soil Resources (BWSR) and approval is being sought by the U.S. Army Corps of Engineers (Corps). Bank V will have 14.26 acres of BWSR and Corps approved new wetland credits and 7.952 acres of BWSR-only approved wetland credits. NRRI/UMD will sell these credits as replacement credits for economic development projects in Northeast Minnesota.
