Despite efforts to minimize its impact, the wind energy project construction affected state protected Illinois Chorus Frog habitat in the Illinois sand prairies. Glacial Sands Wind Power and the Illinois Department of Natural Resources (IDNR) agreed that a mitigation fund would be established to off set unavoidable impacts resulting from the project.

The Conservation Solution

The IDNR designated The Conservation Fund to hold the mitigation fund and implement projects that result in conservation benefit to the Illinois Chorus Frog.

outcome Highlights

The Fund has protected, and in some cases restored, a total of 14,751 acres of land. These lands have been protected and restored using the $21 million Flanagan South Pipeline Mitigation Fund plus complementary funding from partners, including state and federalland conservation programs and private foundations.


The Conservation Fund is working with the IDNR, Heartlands Conservancy and other partners to identify priority acquisition and restoration sites that would benefit the Illinois Chorus Frog and has begun reaching out to potential project partners. The goal is to provide landscape-scale benefits to the Illinois Chorus Frog.


This project can generate enough electricity to satisfy the annual consumption needs of more than 166,000 homes.
