Deer season: public land and Managed Forest Law
The tax roll marks parcels that are government-owned or enrolled in Wisconsin’s forest tax programs. In Winnebago County:
- Federal-owned: 2,727 acres in 102 parcels
- State-owned: 15,402 acres in 1,352 parcels
- County-owned: 6,003 acres in 947 parcels
- No parcels are listed as open Managed Forest Law land.
- Managed Forest Law, closed (no public access without permission): 2,206 acres
In WI 2026, color the map by Auxiliary Class of Property to see these parcels, and tap one for the owner and acreage. The acreages are whole-parcel areas from the tax roll: a parcel that is only partly enrolled counts in full, and the tax roll doesn’t show posted areas or access routes. Before you hunt, check the DNR’s map of private forest land open to the public and the signs on the ground.
