Here is WI Law:
Trespassing:
Landowners suspecting that individuals are trespassing on their
property should
contact their local Sheriff’s Department or other local law
enforcement agency
. Conservation Wardens do not have the authority to investigate
trespassing complaints. Any person convicted of trespassing is subject to a penalty of
up to $1,383. According to s. 943.13, of the Wisconsin Statutes, it is illegal to:
• enter land of another without the express or implied consent of the owner or occupant
of the land, or
• enter or remain on land after having been notifi ed by the owner or occupant not to
enter or remain. A person has received notice from the owner or occupant if he or
she has been notifi ed personally, either orally or in writing, or if the land is posted.
Remember:
Although hunters are required to make a reasonable effort to retrieve
game they have killed or injured, hunters may not trespass to retrieve such game,
even if the game was shot from outside the posted area. Ask fi rst for permission.
