Beaver Lifespan: How Long Do Beavers Live? - Misfit Animals

Factors That Determine the Lifespan of Beavers

The most common factors that affect beavers’ lifespan include diet, habitat, predators, and disease. These can all negatively affect their lifespan in different ways.

As wild animals, beavers have to fend for themselves. They rely on their abilities to forage and avoid predators and can be influenced by potential environmental factors.

Diet & Food Shortages

Diet is one of the most important factors influencing a beaver’s lifespan. Beavers are primarily herbivores, and their diet consists mostly of aquatic plants and tree bark.[2]

A healthy diet of these foods provides the beaver with essential nutrients that help to keep them healthy and increase their life expectancy.

If there’s a food shortage, beavers may become sick with diseases as their immune system deteriorates. When food runs out, they also have to relocate, putting them in increased danger of being attacked by predators.

Habitat & Environment

Habitat also plays a role in determining a beaver’s lifespan. Beavers that live in areas with clean water and plenty of food sources tend to live longer than those that live in less ideal habitats.

Additionally, beavers that have access to shelter from predators and harsh weather conditions also tend to live longer than those that do not.

Predators

Predators can also influence a beaver’s lifespan directly.

Beavers are preyed upon by a variety of animals:

• Wolves
• Coyotes
• Bears
• Humans

While most predators only kill young or weak beavers, some pose a serious threat to even healthy adults.

Health & Diseases

Disease is another factor that can affect a beaver’s lifespan. Beavers are susceptible to a variety of illnesses, including rabies, distemper, and mange.

These diseases can easily kill a beaver, especially if they are young or old.
