Our Mission

“The Friends of the Cedarburg Bog support stewardship, understanding, and appreciation of the Bog through land management, preservation, research and education.”

The Friends of the Cedarburg Bog is a nonprofit 501(C)(3) organization that supports preservation, stewardship, appreciation, and scientific study of the Cedarburg Bog in cooperation with the Department of natural Resources and the University of Wisconsin-Milwaukee Field Station. The Cedarburg Bog is one of the largest and most biologically interesting wetlands in Southern Wisconsin. The Bog Friends seek to make the public more aware of the Bog’s uniqueness by creating opportunities for people to visit. It organizes projects and volunteer workdays for invasive species control; it improves facilities for educational and scientific programs, and supports long term monitoring and research.
