At 2,200 acres, the Cedarburg Bog is one of the largest and most diverse wetlands in southern Wisconsin. In recognition of its outstanding natural qualities, it was designated a State Natural Area in 1952, and was the second property in the state added to this program. The UWM Field Station was founded in 1964, on adjacent lands donated by the Wisconsin Chapter of the Nature Conservancy. The Cedarburg Bog supports an array of unusual plants and animals. Cedar-Tamarack and hardwood swamps, deep and shallow marshes, several bog lakes and a patterned peatland or “string bog” make this area unique.
