Nachusa Grasslands consists of 3100 acres of prairie remnants, restorations, and reconstructions located between Oregon, Dixon and Franklin Grove, IL. Remnant prairie knobs were protected from the plow by an unfarmable overlay of St. Peter Sandstone. Starting in 1986 with the purchase of 250 acres, The Nature Conservancy has gradually recreated a vision of 1800 Illinois' mosaic of prairie, savanna and wetlands. Hundreds of dedicated volunteers have collected seed to replant former corn and bean fields.

It is an ongoing effort to remove non-Illinois plants from the preserve. Nachusa Grasslands is home to over 700 native prairie plant species as well as many important birds, insects, and reptiles.

The preserve is open to the public every day from dawn to dusk.  The main Lowden Road entrance has an information kiosk, with maps, and a Port-a-John but no water.
