Braidwood Dunes and Savanna Nature Preserve protects a diversity of habitats, including prairie, savanna and wetland.
A unique feature of the site is its crescent-shaped sand dunes, which formed when the area was the shoreline of the ancient glacial Lake Wauponsee.
Wildlife found at the preserve includes more than 30 bird species, in addition to amphibians and reptiles such as the tiger salamander and the six-lined racerunner.
The preserve is also home to a variety of plant species, including huckleberry, prickly pear cactus and tubercled orchid.
