Public Use Information

Draft Compatibility Determination

The Horicon National Wildlife Refuge Complex (Green Bay, Gravel Island, Horicon, and Fox River National Wildlife Refuges) is proposing to allow Research, Scientific Collecting and Surveys by Third Parties to occur on the refuges. We are seeking public comment on allowing this use on the refuges. You are invited to review the draft compatibility determination document that includes our justification and analysis. This use has previously been allowed to occur on the refuge and through this process we are expanding opportunities for research, scientific collection, and surveys conducted by non-Service entities to contribute to the enhancement, protection, use, preservation, and management of wildlife populations and their habitats. These uses also help fulfill the mission of the National Wildlife Refuge System and the purposes of the refuge. The document is available May 15th through May 30th. Comments may be provided to or by phone 920-387-2658.
