Clean Air & Water
Our mission is to create an enduring legacy of natural land in northern Illinois for people, plants, and animals. Since 1958, the Natural Land Institute has helped to preserve and restore more than 16,000 acres of natural land in northern Illinois.
For 57 years, the Natural Land Institute has helped residents of northern Illinois conserve the land they cherish. We are one of the oldest private conservation groups in the Midwest.
Serving as a regional land trust, the Institute accepts donations of properties, buys lands, manages natural areas, and helps landowners establish legal agreements that permanently limit harmful use and development.
