About Us

Gerald E. Eddy Discovery Center - Southeast Michigan's visitor center in the Waterloo Recreation Area The Waterloo Natural History Association is a non-profit organization which was established in 1981. Its purpose is to provide both educational and recreational opportunities to people visiting the Waterloo Recreation Area. The Association is composed of concerned citizens who want to support environmental education and help promote the area as a valuable community resource. In order to achieve these goals we depend on your support through donations, memberships and volunteer help.

The WNHA and the Parks Division of the Department of Natural Resources have a unique partnership. As a support organization for the Waterloo Recreation Area the WNHA sponsors projects and provides services which supplement and complement those offered by the DNR. Interpretive programs are presented by WNHA staff throughout the Waterloo Rec. Area, at campgrounds, Outdoor Centers and at the Gerald E. Eddy Discovery Center. Programs covering ecological topics, the local flora and fauna, and history of the area are presented to school groups, organizations and the general public. In addition, the WNHA sponsors special events which include a Maple Sugar Festival in the spring and Sandhill Crane Celebration in the fall. Whether you explore the dark, tangled recesses of the black-spruce bog, or enjoy listening to the chorusing of woodland frogs, the Waterloo Natural History Association will help you discover the natural environment of the Waterloo Recreation Area.
