The European beaver (Castor fiber)

The calm deep stretches of the Tarn are good areas to settle for the European beaver, which lives in a lodge dug into the river bank. An essentially vegetarian animal, it bases its diet on cellulose. It eats young shoots, bark, aquatic plants, and foliage that is abundant in the riparian forest. It is thus useful in regulating the woody vegetation of river banks, facilitating the development of riverside fauna and flora. Through its activities, it prevents the potentially dangerous accumulation of dead wood during floods. It does not build dams.
