North America’s largest land mammal
Adult bulls (males) weigh up to 2,000 pounds – the size of a small car! Look for the newest bison calf, colored reddish-orange, staying close to mom. Bison are a conservation success story. Once numbering in the millions, bison were hunted to near extinction after the Civil War. Today, thanks to efforts to save them, there are nearly 20,000 bison in managed herds across the country. Bison play an important role in keeping plains ecosystems healthy by aerating soil with their hooves, creating seasonal wetlands with their wallows and depositing seed-laden fertilizer.
