The European beaver is a large, semi-aquatic rodent native to Europe and parts of Asia. They are known for their distinctive flat tails and webbed feet, which help them swim efficiently. European beavers primarily inhabit rivers, streams, and ponds, where they build dams and lodges using branches, mud, and other materials. These beavers play a crucial role in their ecosystems by creating wetlands that support diverse wildlife. Their dam-building activities can help regulate water flow and improve water quality, making them important contributors to environmental health. European beavers are currently protected in many regions due to past overhunting and habitat loss.
