  • U.S. Fish and Wildlife Service Seeking Public Comments for Development of Hunt Plans

    The U.S. Fish and Wildlife Service will be hosting open house events in three communities before the development of updated or new hunt plans for Horicon, Fox River and Green Bay National Wildlife Refuges. All three refuges currently have comprehensive conservation plans (CCP’s) completed which identify goals, objectives, and broad strategies for refuge management which includes the hunt programs. However, staff would like to consider any additional public input before starting the environmental assessment process necessary to comply with the National Environmental Policy Act of 1969 (NEPA) and the further development of more detailed draft hunt plans for these refuges. Open house events will be held on: Friday, February 12, 2016, 6-8 p.m. Washington Island Community Center Gymnasium 910 Main Road. Washington Island, WI Saturday, February 13, 2016, 2:30-4 p.m. Liberty Grove Town Hall 11161 Old Stage Road, Sister Bay WI 54234 Tuesday, February 16, 2016, 6-8 p.m. Horicon National Wildlife Refuge Visitor Center W4279 Headquarters Road, Mayville WI Thursday, February 18, 2016, 6-8 p.m. Buffalo Town Hall W3205 County Road O Montello, WI 53949 The purpose of these open houses is to offer the public the opportunity to provide input regarding hunting activities on several refuges managed under the Horicon National Wildlife Refuge / Leopold Wetland Management District Complex. Please note that the waterfowl production areas within the Leopold Wetland Management District will not be included in this planning phase. To review current conservation plans for each of these refuges visit: (Horicon and Fox River NWR’s) and (Green Bay NWR).
