Natural History Survey scientists study the plants and animals of Illinois and how they interact among the variety of ecosystems throughout the state. Through its research and other activities, the Survey fosters intelligent and responsible management of the biological resources of Illinois and public appreciation of the state's natural heritage. It is recognized as the nation's premier natural history survey.

Founded in 1858, the Survey, now a division of the Illinois Department of Natural Resources, is headquartered on the campus of the University of Illinois at Urbana-Champaign. Its collections of plant and animal specimens are among the oldest in North America.
