Why Are Beavers Important?

Beavers are important because they provide many ecosystem services. Beavers are famous for building dams in streams and rivers to create ponds. These ponds provide a habitat for sensitive plants and many animal species, including fish, amphibians, reptiles, and birds. The ponds also help to filter water and improve water quality.

Do Beavers’ Teeth Grow Forever?

Yes, beaver teeth continue to grow throughout their lives. This is why they must always chew on things – it wears down their teeth. Otherwise, their teeth would get too long, and they wouldn’t be able to eat.

The teeth of the beaver are like chisels that can chew up a 5-inch diameter tree in 60 seconds.

Food/ Eating Habits

The beaver is a herbivore. Beavers eat bark, leaves, and twigs of willow, poplar, and aspen trees. During the summer and fall, beavers spend time in dam building and stockpiling foods for future use. In winter, the beaver’s diet consists of these trees’ buds and inner bark. The beaver stores food for winter in its lodge.


The beaver has few predators. Humans hunt beavers for their fur. Large birds of prey, such as eagles and owls, will sometimes attack beavers. But most animals stay away from the beaver because it is large and can defend itself with its sharp teeth and powerful tail. Beavers stay in open water for safety from predators and make underwater entrance holes.

Beaver Habitat/ Where Do They Live?

The beavers are found in North America, Europe, and Asia. In North America, it is found in Canada, the United States, and Mexico. In Europe, it is found in Norway, Sweden, Finland, and Russia. In Asia, it is found in China and Mongolia. Beavers live in streams or rivers with ponds or lakes. They build their homes, called lodges, in the ponds or streams. The lodge contains underwater entrances and is made of sticks and mud.

Beavers are very good swimmers and have webbed hind feet and a flattened tail that helps them steer. Their fur is also waterproof, keeping them warm and dry when swimming.


how big can a beaver get

Beavers are social animals that live in family groups called colonies. A colony can have up to 10-12 individuals, and all the family members work together to build their lodges and dams. Beaver families are territorial and defend against other families.

Reproduction and Development

Sexually mature beavers commonly form pair bonds for life. In the winter, from January to late February, they breed, and female beavers give birth to two to four kits or baby beavers in the spring. Female beavers reach sexual maturity at 1.5–3 years of age.

Beavers reproduce sexually and have a gestation period of 128 days. The young kits are born blind and deaf and will stay with their mother for the first year of their lives. After they leave their mother’s care, they will find their mate and start their colony.

Conservation Status

The beaver is not considered to be endangered. However, hunting and habitat loss are a threat to the beaver population. When their habitat is destroyed, they have nowhere to live. They are also hunted for the fur trade.

Trapping and Removal of Beaver

Unfortunately, beavers can become a problem by accidentally damming up man-made streams, which might cause significant flooding.

If you have a beaver problem, the best course of action is to call a professional trapper. Trapping and removal is the only way to get rid of beavers and should be done by someone who knows what they are doing. Once the beaver is trapped, it will be relocated to a remote area where it will not be a nuisance.

If you have a pond or lake on your property, you can also take steps to prevent beavers from damming it up. You can do this by installing a wire fence around the perimeter of the pond or lake. The wire fence should be at least 6 feet (1.8 meters) high and buried underground at least 2 feet (0.6 meters). You can also use beaver baffles, which are devices that prevent beavers from swimming into an area.
