The largest mammal in North America is the American bison. These massive creatures, known for their large frames, can weigh up to 2,000 pounds and stand about 6 feet tall at the shoulder. Once roaming the plains in large herds, their population significantly declined due to overhunting and habitat loss in the 19th century. Conservation efforts have helped to stabilize and increase their numbers, and today, they are often seen in national parks and reserves. The American bison holds great cultural significance for Native American tribes and symbolizes the American wilderness.
