Bunker North Flatwoods

Bunker North (Clayton Smith) Flatwoods

Originally known as Clayton Smith Flatwoods, Bunker North Flatwoods gets its cathedral-like character from the large old pin oaks that dominate the canopy. Flatwoods have a clay layer below the surface that keeps water from readily draining. Consequently, the flatwoods are very wet in spring and fall, perfect for Pin Oak and other wet-adapted plants.

The 76 acre site is new to restoration. Volunteers have worked to remove invasive species, spread native seed, and much more for several years now. It’s exciting that results are evident already. We invite you to join the North Branch Restoration Project and Centennial Volunteers as we restore this oak woodland to health!



Enter the preserve from Harts Road, just west of Touhy and Caldwell. The approximate address is 6600 W Harts Road in Niles, IL. Look for yellow “Volunteers” signs for the location.
