Funk's Grove Nature Preserve is an 18 acre tract of land within a larger parcel known as Funk's Grove, one of the largest remnants of virgin forest in Illinois. The grove contains mesic upland forest of the Grand Prairie Natural Division. Funk's Grove has been protected for 160 years, however, the high quality forest is experiencing succession. White and bur oaks, representing the largest and oldest trees, are gradually dying out and the more shade tolerant sugar maples are becoming more abundant. The preserve is also rich in woodland wildflowers, and is ideal for wildlife, including some 53 species of birds and many common mammals. The large sugar maples outside the preserve are responsible for the ever-popular maple syrup production in the area.
