Wilderness Landscape & Natural Heritage

The Cook County Forest Preserves, situated around the bustling metropolis of Chicago, provide an essential natural retreat within one of the most densely populated areas in Illinois. Spanning approximately 70,000 acres, these preserves are composed of diverse ecosystems including forests, prairies, wetlands, and rivers, which support abundant wildlife and plant species.
