The biber, commonly known as the beaver, is a large, semi-aquatic rodent found primarily in North America and Europe. It is known for its distinctive flat tail, webbed feet, and thick fur. Beavers are famous for their ability to build dams in rivers and streams, creating ponds that provide habitat for various wildlife. Beavers are herbivores, primarily feeding on the bark, leaves, and twigs of trees and shrubs. They play a crucial role in their ecosystems by creating wetlands, which help improve water quality and support biodiversity. Their activities can also influence the landscape, promoting the growth of new plant species.
