Yellowstone National Park officials are reminding hunters that with the opening of hunting seasons on lands surrounding the park, they need to be sure not to stray over the park boundary in their hunting efforts. Most of the park boundary is well marked, but officials emphasize it is the responsibility of the hunters to ensure they do not hunt within the park. The Lacey Act and the Code of Federal Regulations strictly prohibit the killing or removal of any animal, living or dead, from inside Yellowstone. This includes animals shot legally outside the park that cross into, and die within the park. Taking and removing any animal parts, including shed antlers, is also prohibited and violators are subject to penalties including fines, restitution, and the forfeiture of vehicles, equipment and personal property associated with the violations.
