Beavers do not necessarily use the same trees as construction material and as food. Inedible material is more likely to be used as the cap of a beaver family's food cache, the upper part which is frozen in the ice, while the cache itself is composed of edible, high quality branches, which remain unfrozen and accessible.

Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as ...
European beavers are herbivorous, eating "water and river bank plants", including tubers, "rootstocks of myrtles, cattails, water lilies", and also trees, including softwood tree bark. Their long appendices and the microorganisms within make possible the digestion of bark cellulose.
Beavers eat sagebrush and bark from certain tree varieties, as well as twigs, roots, leaves, and vines. Interestingly, they use different woods to build dams , so they aren't eating the same wood ...
The mountain beaver (Aplodontia rufa) [Note 1] is a North American rodent.It is the only living member of its genus, Aplodontia, and family, Aplodontiidae. [2] It should not be confused with true North American and Eurasian beavers, to which it is not closely related; [3] the mountain beaver is instead more closely related to squirrels, although its less-efficient renal system was thought to ...
Trees approaching a diameter of 90 centimetres (3.0 ft) may be used to construct a dam, although the average is 10 to 30 centimetres (3.9 to 11.8 in). Log length depends on the diameter of the tree and the size of the beaver. There are recorded cases of beavers felling trees of 45 metres (148 ft) tall and 115 centimetres (45 in) in diameter.
The beavers already threaten around sixteen million hectares of indigenous forest. [7] Unlike many trees in North America, trees in South America often do not regenerate when coppiced, destroying the forest. [9] As well as felling trees, the animals create dams that drown trees and other vegetation while creating freshwater ponds and lakes. [10]
Those could be wrapping trees with wire mesh or using flow devices on streams to control beaver pond levels to prevent flooding. In some cases, it may involve relocating beavers to places that ...
