Interesting facts about the beaver

  • There are only two different species of beaver: the European beaver (native to Europe and Asia) and the Canadian beaver (widespread in North America). Both species can not mate with each other.
  • The beaver is under protection of species. It is strictly forbidden to catch or hunt beaver.
  • In the 19th century, the beaver was almost extinct. Because of his flesh and fur, he was hunted intensively. Through extensive resettlement programs, however, the beaver's population was able to recover
  • Once beavers have found a partner, they stay together for a lifetime.
  • In the vicinity of arable land, the beaver is not a welcome guest, because it ensures through its buildings for the flooding of fields.
  • The beaver's coat consists of two layers: the upper layer keeps the water out and protects the beaver from wetness. The lower coat is particularly dense and keeps the heat close to the body.
  • Beavers create extensive wooden castles near the shore, which they use as housing. The entrance is under water and therefore not accessible to other animals. Although a full-grown beaver has virtually no predators, its young on the shore would be easy prey for birds of prey.
  • In the beaver's intestine live special bacteria, which break down a large part of the eaten plant material and make it usable for the beaver.
