Keith Zoeller, a member of Rock Falls Rotary since 1990, presented a program on the restoration of a prairie to members of the Rock Falls Rotary Club.  He has developed several such acreages, including the one being shown in photos of 16 acres located upon entry into Gregden Shores.  He brought in samples of the wildflowers and grasses of that location and explained the need for multiple years to restore a prairie, which includes eventually burning off the property to regenerate its growth.
