Bison bonasus, commonly known as the European bison or wisent, is a large herbivorous mammal native to Europe. It is characterized by its massive build, humped shoulders, and long, curved horns. The species primarily inhabits forests and grasslands, where it grazes on a variety of vegetation, including grasses, leaves, and shrubs. Once widespread across Europe, the European bison faced severe population declines due to hunting and habitat loss. Conservation efforts have helped to stabilize its numbers, and today, Bison bonasus can be found in protected areas and reserves, playing a crucial role in maintaining the ecosystem.
