As a Wisconsin Hunter Education Instructor, I listen to the local Warden cover this subject a couple times a year during our classes. Generally, in Wisconsin if this issue occurs, the warden can go on the property and obtain the deer, however, in almost all cases, he then confiscates the animal and then it is donated to the local food pantry...neither party gets what they want....the hunter wants the deer, the land owner doesn't want anyone coming on his land. The wardens all state they hate to be caught in this situation, but, have found, in our area anyway, this is the best way to approach it and deal with it...at least the deer doesn't become wolf/coyote food then. We try to preach to the kids to get permission from land owners far in advance, and, be willing to offer a tresspass fee, even if it is only to get your deer and get out.
