Miller-Anderson Woods

Nature Preserve Area: 
Location and Access: 
From Putnam take Highway 29 north 3.6 miles to the Bureau/Putnam county line. The nature preserve is in both counties and just west of Highway 29.

Special Note: Trails have been developed. Parking, informational signs and toilet facilities are available along the abandoned part of Route 29.

This large preserve contains natural communities representative of the Grand Prairie Section of the Grand Prairie Natural Division. The majority of the bluff area consists of old-growth oak-hickory upland forest with maple-basswood forest occurring in the eroded ravines. Other small, recently acquired communities such as sedge meadow, seep spring and hill prairie add unique vegetation to the already rich diversity. Notable plants include showy orchid and Schreber's aster. Seep areas with large accumulations of peat support marsh marigold and skunk cabbage. Ohio buckeye and queen--of-the-prairie are also present.
