Beaver Population - Bruce Peninsula

Beavers were formerly extirpated from the Bruce Peninsula, but have re-colonized the area after a two century absence, making significant changes to the park landscape. Bruce Peninsula National Park monitors active lodges by counting food caches during helicopter surveys in the fall, just before the freeze-up.
