In partnership with the City of Alton, The Nature Institute has actively managed the 60-acre Heartland Prairie Project, located on the north side of Gordon Moore Park, for more than 30 years. From the first planting in 1977 to current stewardship activities, the Heartland Prairie Project continues to be a top priority of TNI and its dedicated volunteers.

Boasting more than 150 native prairie plant species and harboring a large variety of grassland-dependent birds, Heartland gives visitors a glimpse into the past. TNI stewardship staff use prescribed fire and other land management strategies to control invasive species and promote a healthy tallgrass prairie ecosystem.

Guests can also enjoy the trails with a guide every second and fourth Tuesday of the months of April through October. Please see the events tab for more details.
