Located in Naperville in northern Illinois, Springbrook Prairie Forest Preserve contains 1,787 acres. Most of this land is open fields and restored prairie, with wetlands and a small creek, Spring Brook, flowing through the preserve.
Springbrook Prairie has historically been the best location within DuPage County to find Northern Harrier, Short-eared Owl and Henslow's Sparrow. Henslow's Sparrows have bred regularly since 1997. It is a significant area for breeding grassland birds and wintering raptors. There are also historical records for breeding Upland Sandpiper and Loggerhead Shrike. Springbrook also has a significant colony of Clay-colored Sparrows that have been nesting at the site for 10 years. The first confirmed DuPage record of nesting Turkey Vultures came from here in 2009. At lest two black rails were present in the breeding season in 2000.
This site was chosen as an IBA because it met the criteria for Henslow's Sparrow and Bobolink.
Springbroook consists mostly of grasslands, with a small pond and some wooded areas.
