About The Friends

Friend's 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.

Danielle Bell

Danielle’s passion for the outdoors started as a small child exploring the natural world with my parents. This love and excitement grew with her through college where a field trip to the Cedarburg Bog was her first exposure to our state natural areas and the intact plant communities of Wisconsin. Since graduating, she has spent the past decade working in the green industry and in 2019 started her own company with the focus of reintroducing native plants into the landscape fabric of our cities and suburbs. She enjoys watching these plants heal the land while providing habitats for our native fauna. There is always something new to discover in nature with every step if you take the time to slow down and be present in the moment. Danielle enjoy being able to share her passions with others and expose them to our natural areas in hopes that they will fall in love with them as much as she has.

About The Bog

Natural History of the Bog

The Cedarburg Bog is one of the largest and most outstanding wetlands remaining in southeastern Wisconsin.

With about 2,000 acres, the Cedarburg Bog State Natural Area is a conifer swamp, the largest example of the least abundant type of wetland in the Milwaukee River basin. It offers an ideal location for educating literally thousands of area residents, students and visitors about the vital role that wetlands play in preserving water quality and species diversity in the Milwaukee River Watershed. It contains the largest expanses of cedar-tamarack swamp forest, in addition to marshes, shrub carr, swamp hardwoods and both deep and shallow bog lakes. Its most unusual feature is the presence of a “String” or “Patterned” bog, which consists of stunted cedars and tamaracks alternating with flatter, water areas dominated by sedges. String bogs are typically found further north, and the Cedarburg Bog may be the southernmost string bog in all of North America.

Plants & Animals

The Cedarburg Bog system is made up of about 2,200 acres that include seven or eight plant communities like conifer and hardwood swamps, sedge meadow, marsh, several lakes, fen, and upland forests.

In addition, amphibians and reptiles such as the Blue spotted Salamander, eastern milk snake and snapping turtle can be found. Common mammals include the opossum, masked shrew, little and big brown bat, coyote and white tail deer. Birds that make their home in the Bog include northern cardinal, red-tailed hawk, wild turkey, common yellowthroat warbler and wood duck, among others that use it as a stopover during migration. There is public access at the north and south ends of the bog. The UWM Field Station trails are only open to the public for group use arranged in advance or at public events. Please do not harass or harm the birds, plants mammals or amphibians you encounter.

Animal Lists

Like all species lists, these lists are a work-in-progress. If you see a bird, amphibian, plant or mammal that is not on the list, please report it to Friends of the Cedarburg Bog, c/o UWM Field Station, fieldstn@uwm.edu.
