Restoring More of the Great Prairie

Posted by Forest Preserve District of DuPage County | 8/5/19 10:57 AM

The 358-acre West Chicago Prairie Forest Preserve in West Chicago is one of northeastern Illinois’ premier natural areas, containing more than 600 species of native plants and animals. Not only is the prairie a diverse habitat containing high-quality natural resources but it's also designated a state nature preserve, giving it the greatest protection against the threats of development and improper use. Small footpaths provide visitors the unique opportunity to take leisurely walks to enjoy the prairie’s rare ecosystem, and the preserve is void of picnic tables, large fishing lakes and limestone multipurpose trails to secure the great diversity of its native plants and animals.

The West Chicago Prairie Stewardship Group helps the Forest Preserve District manage the prairie and its natural resources. Its volunteers contribute significantly throughout the year by removing invasive woody vegetation, eliminating exotic weeds, collecting seeds from native grasses and forbs, and sowing the seeds at restored areas. The stewardship group volunteered nearly 85 days (just under 990 hours) each year at the prairie. Much of this work is accomplished during organized volunteer workdays attended by its members and others from the community.

In 2018 the Forest Preserve District hastened a plan to restore a 6-acre area at West Chicago Prairie that had long been deemed a high priority for restoration. The lack of fire over the past half century allowed undesirable woody species including box elder, black cherry, silver maple and others to grow and dominate the area. And although much of the prairie is managed by the West Chicago Prairie Stewardship Group, this area was too overgrown with second-growth trees and invasive species for volunteers to tackle. The Forest Preserve District instead proposed hiring an ecological contractor to remove the trees and other invasives and seed with native species collected from the surrounding prairie. The area would then become one that could be managed by the stewardship group during its volunteer workdays and slowly recover.

The nonprofit 501(c)(3) Friends of the Forest Preserve District received a Community Stewardship Challenge Grant from the Illinois Clean Energy Community Foundation to restore the habitat at West Chicago Prairie. For every dollar the Friends raised, the ICECF donated $3 up to $21,000. The foundation also then contributed an additional $4,000, because it expects volunteers to log 400 hours before October 2019 at West Chicago Prairie.

Today the habitat is well on its way to becoming healthier and more sustainable. The restoration of these acres in the larger West Chicago Prairie connects a formerly fragmented landscape, creates even greater habitat for wildlife and provides additional leisure opportunities— like watching wildlife, seeking blooming wildflowers and taking in beautiful vistas — for visitors.
