NATURAL LAND INSTITUTE
The Natural Land Institute exists to create an enduring legacy of natural land in
northern Illinois for people, plants, and animals. Since 1958, the NLI has helped
to preserve and restore more than 16,000 acres of natural land in northern Illinois.
For 58 years, the Natural Land Institute has helped residents of northern Illinois
conserve the land they cherish. They 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 ageements that permanently limit
harmful use and development. NLI preserves include Burr Oak Valley,
Carl & Myrna Nygren Wetland, Colman Dells, Hanover Forest, Kyte River
Bottoms, Lyndon Prairie, Milan Bottoms, Nieman Marsh, Pecatonica
Ridge Prairie, and Pecatonica Woodlands.
