On Saturday they practiced a kind of eco-time travel, removing invasive species that have crowded out native species like white and burr oaks, redtop grass and rough blazing star. The goal is to restore a habitat that more closely resembles the area&rsquo;s original prairies and wetlands.</p><p>Though 209 native plant species have been identified at Beaubien, biodiversity has plummeted since invasives took root. Native species like big bluestem grass and buttonbush are not just visually appealing &mdash; they hold the soil against erosion and harbor wildlife. Biodiversity in prairie systems <a href="http://www.esajournals.org/doi/abs/10.1890/03-5273?journalCode=ecap">can have a dramatic impact on an ecosystem&#39;s properties</a>.</p><p>In January, of course, those iconic (and exquisitely named) wildflower species would not be visible anyway, but the frozen ground afforded the volunteers a chance to clear away the invasive species that have colonized Beaubien without trampling the rest of the forest floor.</p><p>The invasives are the usual suspects for Northeast Illinois: <a href="http://www.wbez.org/story/news/botanic-garden-combats-buckthorn">buckthorn</a> and honeysuckle, mostly. The shrubs grow voraciously, crowding out sunlight otherwise destined for young oaks and other native plants. Volunteers sawed and hacked through the plants&rsquo; spindly branches, leaving oaks and other native species intact. They piled the brush onto a bonfire and applied herbicide selectively to the stumps of cleared invasives.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/Beaubien_1938_0.jpg" title="The site of Beaubien Forest Preserve in 1938.

Maintaining the forest preserve is community work, too, according to Milkert.</p><p>&ldquo;The story of Beaubien is it&rsquo;s a real collective effort,&rdquo; she said. Other volunteers with Friends of the Forest Preserves clear away cottonwoods with chainsaws, some 350 local students had hands-on ecology lessons onsite last fall through&nbsp;<a href="http://www.fieldmuseum.org/ceep">Calumet Environmental Education Programs</a>, and a group called <a href="http://www.fishin-buddies.net/">Fishin&rsquo; Buddies</a> connects local kids to nature through fishing trips to Beaubien&rsquo;s Flatfoot Lake. Students, interns and volunteers logged more than 1000 hours of work at the site in 2011, Milkert said.</p><p>Stephanie Ryan, a graduate student at Northeastern Illinois University, also named community among her reasons for spending Saturday morning in the woods. &ldquo;It&rsquo;s something we need more of these days,&rdquo; she said.</p><p><em>Follow Chris on Twitter <a href="https://twitter.com/Cementley">@cementley</a>.</em></p></p> Tue, 08 Jan 2013 05:00:00 -0600 http://www.wbez.org/blogs/chris-bentley/2013-01/restoring-prairieland-calumets-industrial-corridor-104751 How the invasion of Asian Carp are affecting an Illinois town http://www.wbez.org/episode-segments/2011-06-22/how-invasion-asian-carp-are-affecting-illinois-town-88187 <img typeof="foaf:Image" src="http://llnw.wbez.org//segment/photo/2011-June/2011-06-22/Carp on truck.JPG" alt="" /><p><p><em>Eight Forty-Eight</em> has been exploring waterways that link the Great Lakes to the rest of the world as part of <a href="http://www.wbez.org/frontandcenter" target="_blank"><em>Front and Center</em></a> – WBEZ’s series looking at some of the critical issues facing the Great Lakes.
