Why You Should Visit
Indian Boundary Prairies, a cluster of five prairie remnants just south of Chicago, comprise the largest remaining example of high-quality grassland in Illinois and one of the best in the Midwest. With this great diversity of plant and animal life, the Indian Boundary Prairies are a sort of biological "ark" for the future—a living flotilla of hope for the inhabitants of Illinois' once vast prairie community. Because of their importance, a portion of the Indian Boundary Prairies has been named a National Natural Landmark by the U.S. Department of the Interior.
In 1971, the Gensburg brothers donated 60 acres to TNC to launch the preserve. Fifty years later, the Indian Boundary Prairies are still collaboratively managed between TNC and Northeastern Illinois University. Altogether, the Indian Boundary Prairies have expanded to approximately 468 acres (358 acres managed by The Nature Conservancy) and reside within the municipalities of Markham and Harvey, border the city of Midlothian, and are positioned around two major highways. This placement of the prairies surrounded by community offers unique challenges and opportunities for the promotion of the intersection of people and nature and the connection of managed prairie sites with the local communities, in addition to grassland restoration.
