The Refuge is proposing to update the existing Hunt Plan and to open new areas and species during the Wisconsin state seasons beginning in the 2017/2018 season.
The proposed changes would open additional acreage (231 acres) to deer and upland game (squirrel, pheasant, partridge, and rabbit) hunting on Horicon NWR, would open additional acreage (80 acres)to deer hunting on Fox River NWR, would open wild turkey hunting on Horicon NWR, and would add migratory bird species (geese) to migratory bird hunting for Learn to Hunt and special hunt programs on Horicon NWR.
A Draft Environmental Assessment and a Draft Hunt Plan are available for public comment regarding the proposed hunting activities on these refuges.
The 30-day comment period will run from July 9, 2016 through August 9, 2016. Please review the proposed changes and provide written comments to Horicon NWR, W4279 Headquarters Road, Mayville, WI 53050, or by email to email@example.com .
