Overview
- The National Park Service announced Thursday that individual tent and group campsites at Three Mile Campground are closed through July 31 with shelters remaining open and the closure subject to extension.
- Park staff documented a single wolf repeatedly sniffing and pawing at tents, dragging backpacks away from camps, and entering a tent, behavior the park says shows habituation and a reliance on human food.
- During the closure the park will step up daytime hazing—shouting, stomping, clapping, airhorns and paintball deterrents—install noise‑producing alert devices at Three Mile, Rock Harbor and Daisy Farm, and patrol closed areas.
- Officials are enforcing the 2026 food‑storage rules requiring lockers or animal‑resistant hard containers and are urging visitors to secure food and scented items because a food‑conditioned wolf was euthanized last summer after repeated incidents.
- Researchers report about 37 wolves on Isle Royale this winter and a sharp drop in moose numbers, a dynamic park staff say may increase wolves’ interest in human food and complicate long‑term management choices.
