When I think about finding a home where the buffalo roam in the United States, I think of South Dakota, North Dakota (home of the World’s Largest Buffalo and the National Buffalo Museum), or Wyoming. I don’t necessarily think of Illinois. But you can find roaming bison in Illinois at Midewin National Tallgrass Prairie in Wilmington.

The act mandated that the land be used to conserve and restore the native populations of wildlife (including fish and plants), be used for education and research, allow for continuing agricultural use, and provide recreational opportunities.

In 2004, the prairie opened to visitors after a period of ecological restoration. Visitors can walk among the nearly 7,000 acres of the Illinois prairie that are open to the public, watch for buffalo in Illinois, and visit the army bunkers on the property.
