    Study Notes

    Physical Characteristics

    • Beavers are semi-aquatic mammals and are the largest rodents in North America and the second largest in the world.
    • They have broad, flat tails and powerful front teeth that grow continuously throughout their lives.
    • Beavers can weigh over 50lbs (25 kg) and live up to 24 years.

    Diet and Eating Habits

    • Beavers do not eat wood, but instead eat leaves, twigs, and the inner bark of deciduous trees, as well as shrubs, aquatic plants, and grasses.

    Behavior and Abilities

    • Beavers are nocturnal, being active mostly at night, and are slow on land due to poor eyesight.
    • They are excellent swimmers and can stay underwater for up to 15 minutes.
    • Beavers have good hearing and a keen sense of smell.

    Habitat and Dams

    • Beavers construct dams using wood, mud, and stones to create ponds that protect them from predators.
    • They often build lodges out in the middle of their ponds, which serve as a place to rest and keep warm.
    • By cutting down trees and building dams, beavers change the face of the land around them and create habitats for many other plants and animals.

    Conservation Status

    • Historically, beavers were hunted for their fur, leading to a significant decline in populations.
    • Today, conservationists recognize the beaver's important role in creating healthy habitats and work to protect them.
    • Beavers have been reintroduced to some of the places they were lost, and in many places they are now thriving.
