EarthCam teamed up with the U.S. Forest Service to take visitors to the heart of the Midewin National Tallgrass Prairie in northeast Illinois with live webcam views. Peek in on a small herd of bison, which was introduced as a 20-year experiment in restoring the landscape to the native tallgrass prairie. Between the hours of 6 AM - 6 PM local time, track the herd as they graze, which is essential to reviving and sustaining a more diverse habitat for birds and wildlife.
