Willowbrook Wildlife Center serves as a rehabilitation center for native and migratory wildlife, treating more than 9,600 animals a year. It is the only publicly funded wildlife rehabilitation facility in DuPage County and one of the few in northeastern Illinois to treat native and migratory birds. In addition to the Willowbrook Wildlife Center, the preserve includes nature trails, a butterfly garden and outdoor native wildlife exhibit, including a sandhill crane exhibit. The preserve serves as a resource for understanding the natural world and provides learning experiences at Willowbrook Wildlife Center, a wildlife rehabilitation facility. The center teaches visitors how to live in harmony with diverse, healthy wildlife populations.
Willowbrook has a one-mile nature trail that provides an opportunity to learn about wildlife and the prairie, savanna, woodland and wetland habitats of the county. A half-mile outer loop and a shorter inner loop travel through 40 acres of restored habitats complete with interpretive signs and inviting benches.
