The activity of gnawing on trees and other woody vegetation is fundamental to the North American and Eurasian beaver. This behavior, driven by instinct and necessity, shapes the environment and supports their survival. It’s a continuous process linked directly to dental health and habitat creation.
This activity provides several crucial benefits. Primarily, it keeps their incisors at a manageable length. Beaver teeth grow continuously, and without consistent wear, they would become overgrown, preventing the animal from feeding. Furthermore, harvested trees serve as building materials for dams and lodges. These structures modify water flow, create wetlands, and provide safe shelter from predators.
