Welcome to the Illinois Department of Natural Resource's Website

Here you will learn about the diversity of the prairie state: from Chicago's Lake Michigan shoreline to the fertile soils of the heartland, to the forests and wetlands of the state's southernmost boundaries, Illinois is rich with history, natural resources and scenic beauty.

Find out what's new at the Department, learn its history, follow legislation, download applications for licenses or permits or just learn more about the world around you.
