Eurasian Beaver

The Eurasian beaver is a large, semi-aquatic rodent and a natural ecosystem engineer. After centuries of hunting, it has made a remarkable comeback through protection and reintroduction.

Interesting facts

  • It is the largest rodent in Europe and Asia.
  • It cannot interbreed with the North American beaver, which has a different number of chromosomes.
  • Beaver dams slow floods, store water in droughts and create wetlands full of wildlife.
  • Beavers were hunted for fur, meat and castoreum, a scent used in perfumes.
  • Beavers have been reintroduced to Scotland and England, and wild releases in England were licensed in 2025.
  • Their orange teeth are strengthened with iron.

Behaviour

Beavers live in family groups and are mostly nocturnal. They build lodges or dig burrows in riverbanks, and build dams where water is shallow.

Breeding and young

After about three and a half months, females give birth to one to four kits in spring. Young stay with their parents for about two years.

Threats and conservation

The species has recovered, but it is sometimes culled because of flooding and damage to trees and crops.
