(10652, Subsection 1-B-1, 2) It is unlawful to insert any metallic or ceramic object into a tree on land of another for the purpose of erecting a ladder or observation stand, unless you have permission from the landowner. You must obtain verbal or written permission of the landowner (or representative) to erect and use a portable or permanent ladder or observation stand and the ladder or observation stand must be plainly labeled with a 2-inch by 4-inch tag identifying the name and address of the person or persons authorized by the landowner to use the observation stand or ladder. (Exception: Portable ladders or observation stands used on land within the jurisdiction of the Maine Land Use Regulation Commission and attended by the person who owns the ladder or observation stand shall not require landowner permission or labelling, but permanent ones do. (Note: For additional information on the use of private property, see page 35.) Observation stands do not include portable blinds utilized at ground level that remain in the physical possession of the hunter.
