Illinois preserve prepares for bison

A herd of bison stand on scorched ground from a controlled burn at Dunn Ranch in Hatfield, Mo. The bison population in the United States was decimated by overhunting, but a 2007 U.S. Department of Agriculture census shows more than 198,000 bison on private properties across the country, with 1,265 residing in Illinois.
