You may see signs on the way to Blackthorn Hill Nature Preserve that say Road Closed. The bridge northwest of Blackthorn is being replaced. So there are no closures coming from the southeast (Galesburg side). Enjoy! Spring is here! 

Western Illinois Nature Group was created to find and purchase a forested property in west central Illinois to accomplish our goals. We seek the financial support and encouragement of area communities and organizations, as well as the dedication of our membership, to preserve a beautifully wooded area for enjoyment well beyond this century. The generosity of corporate and private foundations and local businesses is essential. 

Our Membership year is April 1-March 30

Illinois Recreational Access Program (IRAP)

During the month of October and December 16-31 annually, trails will be closed.  If someone is parked in the IRAP parking space in the parking lot, an archery deer hunter is on the property hunting.  This pays our bills.  Please be safe and respectful.  Wear bright colored clothing, limit your visit to the parking lot area, and stay quiet please.  Only IRAP authorized hunters are allowed to hunt on this property and only according to IRAP rules and regulations.  Violators will be turned in to the authorities. 

Click on IRAP on the left menu  here, or check out their website to learn more.
