Midewin National Tallgrass Prairie is the first national tallgrass prairie and, at 19,000 acres, the largest piece of contiguous open space in northeastern Illinois.
Midewin was established in 1996 on the former Joliet Arsenal. It is currently a "prairie under construction" as staff and volunteers restore the land from war plants to prairie plants. We offer many ways for you to enjoy your public land through hiking, biking, horseback riding, bird-watching, hunting and volunteering.
Don’t wait until spring to get back to the prairie, there is still plenty happening at Midewin! Our 2013 winter lecture series is a definite “don’t miss” this year. All lectures begin at 7pm at the Midewin National Tallgrass Prairie Welcome Center (or Hotshot building if additional space is needed). Doors open at 6:30pm with refreshments provided by the Midewin Tallgrass Prairie Alliance.
The Midewin Tallgrass Prairie Alliance Fundraiser can help you add some vibrance to your yard with native flowers, grasses, shrubs, and trees. Check out the Midewin Tallgrass Prairie Alliance website to get more info and to download your order form today.
