Knowing what habitat an animal prefers – what it likes to eat, where it likes to rest, safety to bear young, a place to find a cool drink of water – provides visitors with an advantage for seeing wildlife. Animals will move between areas to get food in one area, cover in another, and water in yet another. The National Bison Range has some wonderful native habitat within its boundaries. Since the refuge is over 100 years old, the area was never cultivated and much remains as it was. Today, refuge managers and biologists look at the best way to maintain the native habitats by using tools such as prescribed burns and integrated pest management to control non-native invasive weeds and keep native plants healthy.
