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.
