Red-Headed Woodpeckers are regularly spotted here. 

In 1995 the Sebenthaler Company sold this property to The Nature Conservancy, who then turned it over to the Ohio Department of Natural Resources, Division of Wildlife. Beaver Creek Wetlands Association volunteers built the recycled plastic and fiberglass boardwalk, the tower and kiosk, and the Division of Wildlife completed the wooden boardwalk. Bob Siebenthaler donated funds for Nan’s Tower in memory of his sister.

Siebenthaler Fen is managed as part of the Beaver Creek Wildlife Area.

Siebenthaler Fen is the crown jewel of the wetland corridor and enjoys year-round use by school groups, birdwatchers, and wildflower enthusiasts. A boardwalk takes you past wet woods, the fen, Beaver Creek, the information kiosk, and the observation tower.

The trail is accessible by wheelchair with broad areas to turn around. Siebenthaler Fen is a hunting area from September through January. Visitors should wear bright colors during hunting season.

The 380-acre Beaver Creek Wildlife Area contains a unique wetland complex in southwestern Ohio. The general topography of the area is flat to moderately rolling and is located in the Till Plains Eco-Region of Ohio. The Beaver Creek wetland corridor is thought to be related to the old Teays River system that existed prior to the glaciers. The area can be easily reached from I-675 or OH-35.

The Beaver Creek Wildlife Area consists of a mosaic of wetland types, including shrub swamp, wet meadow, and wooded riparian corridor. The remaining upland areas off of New Germany-Trebein Road have been converted to a prairie. The 50-acre freshwater fen is located off of Fairgrounds Road and can be viewed from the boardwalk and observation tower.

Purchasing of land for this public hunting and wildlife observation area began in 1990 with the assistance of The Nature Conservancy and Beaver Creek Wetlands Association. The ODNR, Division of Wildlife purchased 130 acres from the Siebenthaler Nursery to protect and enhance the Siebenthaler Fen. This unique wildlife area contains five of six wetland types found in Ohio. The primary objectives of managing the area are to protect, preserve, restore, and enhance wetlands and improve and protect habitat for nesting and migratory wetland wildlife species. The area will be managed to provide quality recreational opportunities to wildlife enthusiasts. Three wetlands have been either constructed or restored to improve wetland and wildlife diversity.
