NATURE AND THE ENVIRONMENT Why do beavers destroy trees?

They do so to eat because these rodents are vegetarians. In the spring and summer there is a wide variety of plants, young shoots and tubers for them to eat but bark is their main source of food. Under normal conditions they store enough twigs and branches in the beaver lodge to see them through the winter but if their stores run out, they go off looking for their preferred food – bark from poplar and birch trees.
The bark is too thick on the trunk and the branches are too high for a beaver because it can’t climb. There is only one solution: fell the tree to get to the softer bark on the twigs and branches. Once they have gnawed off the bark, they use these branches to build and repair their dams.
