Bison are large, powerful animals that roam the grasslands of North America. They are known for their massive heads, thick fur, and strong build. Bison can weigh up to 2,000 pounds and are often seen grazing in herds. These animals play a crucial role in their ecosystem by helping to maintain the health of the grasslands. Historically, bison were a vital resource for many Indigenous peoples, providing food, clothing, and materials for shelter. Today, they are a symbol of the American West and are protected in national parks like Yellowstone National Park. Conservation efforts have helped their populations recover from near extinction in the 19th century.
