Deer at Lyman WoodsLyman Woods
Lyman Woods is 150 acres of oak woods, prairie, and marsh habitats that supports over 300 species of native plants. Discover an amazing diversity of plant life, including six species classified as rare in the Chicago region. Catch a glimpse of animals including deer, coyote, fox, Cooper's Hawks, Great Horned Owls, a wide variety of reptiles, amphibians, insects, and numerous songbirds.

During your visit, you'll find three rare kames, glacially deposited hills of gravel, which support native prairie and oak woods. The most outstanding feature is a 19-acre oak woods that has remained undisturbed since it was purchased by the Lyman family in 1839. Today it serves as one of the few examples of the pre-settlement landscape that dominated the Downers Grove area.

The preservation of Lyman Woods in 1987 represents the cooperative effort of the Village of Downers Grove, the Forest Preserve District of DuPage County, the Downers Grove Park District, and many dedicated individuals.

Belmont Prairie

Belmont Prairie is one of the last original prairies in Illinois. It is an excellent example of one of the few remaining natural prairie habitats that is maintained by the Downers Grove Park District.  The efforts of the District have been rewarded by the Prairie's official designation by the State as an Illinois Nature Preserve, supporting more than 300 species of plant and animal wildlife.  It is an excellent educational and cultural resource for the benefit of District residents and visitors from farther afield.  The Prairie contains a wide variety of quadra-seasonal grasses and other plants in an undisturbed setting.  The animal wildlife that may be observed includes fox, raccoons, meadow voles, opossums, ground squirrels, garter snakes and, occasionally, coyote and white-tailed deer. A nature trail provides pedestrian access.  The prairie is served by a 6 car parking lot located on Cross Street.

The Belmont Prairie is located west of the Downers Grove Golf Course at Haddow Avenue and Cross Street. Parking is available at the trail head on Cross Street.

Dawn to dusk.  Pease note: There are no dogs, bikes, or cross-country skis allowed in the Natural Areas. Thank you for your cooperation.

In December 1842, John Graves purchased two quarter-sections of prairie land from the U.S. government, west of Downers Grove.  This purchase included what are today both Belmont Prairie and the Downers Grove Golf Course.  This piece of land changed ownership numerous times until it was divided in 1890, with one half becoming the golf course and the other remaining prairie, and the block between them being developed in 1920.

Then, in April of 1970, Alfred and Margaret Dupree presented a photograph of a rare prairie wildflower to an expert at the Morton Arboretum, as they were interested if it represented possible remnants of a native prairie.  Upon inspection, it was found that the field had numerous native prairie species, and with the help of The Nature Conservancy, the owners were tracked down and the land was purchased. After officially becoming a part of the Park District, it was named an Illinois Nature Preserve in March, 1994.
