OUR MISSION
The Nature Institute works to foster an awareness and appreciation of the natural world through preservation, restoration, and education.
The Nature Institute (TNI) is a non-profit land conservation and environmental education organization based in Godfrey, IL. Since its founding in 1980, The Nature Institute’s board and staff have worked to foster an awareness and appreciation of the natural world through preservation, restoration, and education.
Each summer TNI hosts about 400 children, grades pre-K through 6th, for Discovery Day Camp, a premier, ACA, nature day camp. Every school year, more than 8,000 area students visit TNI for field trips, including high school and college students. TNI also owns and manages more than 450 acres of protected land, such as the Olin Nature Preserve, the Mississippi Sanctuary, the Kemp and Cora Hutchinson Bird Sanctuary, and the Heartland Prairie Project at Gordon Moore Park. These natural areas provide unique places for the public to experience the diversity of the Riverbend area with its hardwood forests, prairies, and wetlands.

Making the Most of Fall
Let’s hike the preserve and enjoy the trees while they still have their leaves.
Description:
Roaming Naturalists is a monthly hike designed for adults (all ages welcome) that want to learn more about the natural world. Topics will range from birds to plants to insects and beyond. While each hike will have a topic of focus, we will allow the interest of the group and the surprises that nature throws at us to determine what we learn on our hike.
Meet your guide at the trail head parking lot. Hikes will range from 1-2 miles (rarely 3 miles) and easy to moderate terrain. These hikes will occur rain or shine. In the event of icy conditions, or excessive snow, the hike may be canceled. The Nature Institute closes for the weather when Alton Public Schools close.
Program Fees:
Free, but donations are appreciated
Registration Required:
No, but preferred (You will receive a reminder email if you register ahead of time.)
