Government agencies and conservation groups, aided by volunteers, have undertaken numerous restoration projects across US and Canadian prairieland, some of them thousands of acres in scale. In recent years a cadre of private citizens has joined in, restoring prairie to their own properties, from city yards up to 100 acres or more around rural homes and farms. In some cases they’ve re-created prairie where it never was before — on land that was originally forest or wetlands before settlers plowed it for crops.
The hub of this do-it-yourself restoration activity is Iowa, southwestern Wisconsin, northern Illinois, and Minnesota, says Daryl Smith, director of the Tallgrass Prairie Center at the University of Northern Iowa. That’s probably because the region’s native prairie is so precious. Iowa’s, for instance, is down to 1/10th of 1 percent of its original extent.
