The Wisconsin Department of Natural Resources is seeking contractors to manage five wetland mitigation sites through invasive-species control, mowing, and prescribed burns.
- **Government buyer:** Wisconsin Department of Natural Resources (DNR), through the Wisconsin Wetland Conservation Trust (WWCT); sites are in Rock, Columbia, Waukesha, Marathon, and Sheboygan counties.
- **Sites:** Evansville, Heinze, Hickory Hill, McMillan, and Te Stroete. Each site is awarded separately, so bidders may bid on individual sites.
- **Requested services:** Site-specific herbicide treatments, targeted mowing, and prescribed burns with burn breaks. The work is intended to control invasive plants and sustain native vegetation and wetland function. The attachment allocates 40 person-hours to each herbicide treatment.
- **2027 work quantities:** McMillan: three herbicide treatments and one burn for 48 acres. Te Stroete: three herbicide treatments and one 2-acre mowing; its 9-acre burn is anticipated in 2028 or later. Evansville: three herbicide treatments, one mowing of up to 4 acres, and one 40-acre burn. Heinze: two herbicide treatments and one 45-acre burn. Hickory Hill: four herbicide treatments and two mowing tasks covering 4 and 7 acres; its burn of up to 100 acres is anticipated in 2028 or later.
- **Requirements:** Contractors need appropriate pesticide credentials. Prescribed burns require qualified personnel and applicable training, licensing, insurance, burn plans, and permits or DNR approval. Some burns depend on suitable conditions.
- **Organizations mentioned:** The Natural Resources Foundation of Wisconsin is identified as the partner holding the endowment that funds long-term management; it is not identified as a service provider.
- **OEMs and products:** No OEMs, manufactured products, part numbers, or named prospective vendors are identified.
- **Term:** One initial year in 2027 with four possible one-year renewals, for up to five years total. Renewal scopes and prices are reviewed annually and require agreement.
