WILMINGTON, Ill. -- Midewin is another word for "healing or balance.”  And that is just what the Dept of Agriculture is doing on at the Midewin National Tallgrass Prairie about an hour South of Chicago.

It is home to more than 18,000 acres of prairie that has changed hands over the years.

Ecology experts are now trying to "heal" or restore it to how it was about 150 years ago. It's called the Bison Project and is scheduled to take about 20 years.  Experts want to see if the 25 imported bison could help manage or manicure the landscape.  The hope is that it brings back birds, bugs and plants that no longer flourish there.

Two years into the project, they are already seeing results.

"Having just come off a three day breeding bird survey in the bison pastures, it appears that some of the rarities, the numbers are up,” says Drew Ullberg, restoration team leader.  "The amount of prairie left in Illinois is so miniscule yet a project like this is so important because there is less than one-one hundredth of 1% of the prairie left in Illinois.”

Prairie ecologist Bill Glass is ecstatic. 18 more years of this and glass hopes to deliver for the wildlife and its visitors a treat this state hasn't seen in centuries.

"It appears to be working," Glass says. "People can come up on this ridge and see what it was like 200 years ago."

Since the bison experiment began, those 25 or so bison have doubled. There are more than 50. 17 of them are calves. They largely travel together and eat off the land.  The bison are not corralled or chipped. They do as they please where they please on 1200 acres of land.

Wetlands expert Paul Botts explains the effects of the iconic horned mammal is two fold.

"They chewed up the prairie plants and insects and smaller animals.  Birds evolved from that, adapted to that.  You need that for a healthy prairie,” Botts says.  “And they bring the people. Visitorship has zoomed in the last two years.”

On the largest conservation site of any kind in the area, the evasive bison are doing the heavy lifting and eating while healing the prairie.

And they are just getting started.

July is National Bison Month and the Midewin National Tallgrass Prairie is celebrating. If you want to see the bison, bring your binoculars, maybe a bike to get around the prairie a little easier.

Midewin is working to restore the tallgrass prairie, but what was life like for those who lived here before Euro-American agriculture, when the land was mostly tallgrass?

Come and see archaeologists at work as they learn about the people who lived here and the environment in the last years before Marquette and Joliet.
