This bill amends Minnesota Statutes 2024, section 103G.223, to enhance the protection and understanding of calcareous fens, which are unique wetland ecosystems. It prohibits the filling, draining, or degradation of these fens without the commissioner’s approval under a management plan. A significant addition is the requirement that the commissioner must provide a detailed report to permit applicants regarding the potential effects of their actions on calcareous fens. This report must include a description of the fen, its ecological benefits, and the adverse effects anticipated if the permit is granted.

Additionally, the bill mandates the commissioner of natural resources to adopt rules defining what constitutes a calcareous fen. By December 1, 2025, the commissioner is also required to submit a comprehensive report to legislative committees, which will include the proposed definition of a calcareous fen, a scientific rationale for this definition, an explanation of the ecological benefits of calcareous fens compared to other wetlands, and a summary of permit denials related to these fens over the past decade.
