Beavers are significantly less active in cold weather. With plenty of stored food and the security of a strong dam, they can conserve their energy from late fall to early spring. Beaver dens are the key to their winter survival.
Do Beavers Hibernate?
Though they rarely leave their lodges once the temperatures drop, beavers do not hibernate. However, they do prepare carefully for the colder months. Beavers gather vegetation to store in underwater caches, so they can eat without needing to forage throughout the winter.
Beaver Dens and Dams
Beaver dens give these large rodents access to food sources and a quick escape from predators. The pond that forms behind a dam is too deep for the water to completely freeze, so the animals can swim under the ice, store their food, and escape to the beaver den’s underwater entrance.
Damage and Prevention
Beaver dams can cause flooding damage to nearby landscaping, drainage systems, and basements. Beavers also strip bark and cut down trees on nearby properties for both winter food storage and dam building. Residents concerned about a beaver den on their property should contact a Trutech wildlife expert for assistance.
