Question

how can you conclude that beavers build fairly strong dams

Answer 1

1. They have good sense of architecture. They can sense the direction of water flow. They know how to check pressure. They know when to make curved dams and when to make straight one.

Once the walls are constructed, beavers use mud as insulation. Each year they add more sticks and mud to their home, creating a heavily fortified fortress.

2.Beavers employ their teeth to cut down the trees and limbs used to construct their homes. Fallen trees and limbs are held in their powerful jaws and dragged to their building site.

3.Walls can be 2 to 3 feet thick, providing a secure environment for those inside. When a beaver is safely tucked in his home, bears are the only natural predator strong enough to penetrate the dwelling.

4.The dam is exactly what the name implies, a structure used to raise the water level. The structure that beavers live inside of is often mistakenly referred to as a ‘dam’ when it’s not.
