How do beavers obtain the materials needed to build the lodges?

Beavers obtain materials for building their lodges primarily from the surrounding environment, using their strong teeth to fell trees and shrubs. They typically select softwood species like aspens, willows, and birches, as these are easier to chew. Additionally, beavers gather branches, twigs, and mud to construct and reinforce their lodges, creating a waterproof structure that provides protection from predators and harsh weather. Their natural habitat, often near rivers and streams, supplies them with ample resources for this purpose.
