As with all rodents, a beaver’s front teeth never stop growing.

In the USA, beaver damage costs around $100 million in property costs every year.  

Master Builders: Beavers are renowned for their exceptional engineering skills. They construct elaborate dams using branches, logs, and mud, which create ponds that serve as their homes and provide protection from predators.  

Keystone Species: Beavers are considered a keystone species because of the significant impact they have on their ecosystems. Their dam-building activities create diverse habitats that benefit numerous other species, including fish, amphibians, birds, and insects.  

Semi-Aquatic Mammals: Beavers are well-adapted to aquatic life, with webbed hind feet for swimming and a large, paddle-shaped tail that aids in propulsion and steering. They can remain submerged for up to 15 minutes.  

Monogamous Pairs: Beavers typically mate for life and form monogamous pairs. Both the male (called a "bull") and female (called a "cow") contribute to raising their offspring, known as kits.  

Diverse Diet: Beavers are herbivores and mainly feed on the bark, leaves, and twigs of various tree species, including aspen, willow, and birch. During the winter months, they also consume stored branches and roots.  

Nocturnal Creatures: Beavers are primarily nocturnal, meaning they are most active during the night. This behavior helps them avoid predators and human disturbances while they work on their dams and gather food.  

Excellent Swimmers: Beavers are powerful swimmers, capable of reaching speeds of up to 5 miles per hour (8 kilometers per hour) in the water. Their dense fur provides insulation, buoyancy, and waterproofing.  

Territorial Animals: Beavers defend their territory vigorously against intruders, using vocalizations, scent marking, and physical aggression if necessary. Territories typically include a water source and sufficient food and building materials.  

Valuable Fur: Historically, beaver fur was highly valued for its warmth and durability, leading to extensive trapping and hunting of beavers during the fur trade era. While fur trapping still occurs, it is regulated to ensure sustainable populations.  

Lodges and Burrows: In addition to building dams, beavers also construct lodges or burrows for shelter. Lodges are typically dome-shaped structures made of sticks, mud, and vegetation, with underwater entrances to protect against predators.  

Environmental Engineers: Beavers play a crucial role in shaping their environment through dam-building activities. Their dams can mitigate flooding, improve water quality, and help recharge groundwater aquifers.  

Conservation Status: While beavers are not currently considered globally threatened, they have faced population declines and habitat loss in some regions due to factors such as habitat destruction, pollution, and human-wildlife conflicts. Conservation efforts focus on habitat restoration, management practices, and coexistence strategies to ensure the long-term survival of beaver populations.
