Jefferson Marsh State Wildlife Area and Jefferson Tamarack Swamp State Natural Area
Because of the exceptional viewing, birds have been monitored here since the 1800s. Habitat management balances outstanding wildlife habitat with recreational opportunities for visitors. At 3,000 acres, the area ranges from open water marsh in the south to a 900-acre tamarack bog in the north that is the Jefferson Tamarack Swamp State Natural Area. This is the largest forested wetland in Jefferson County and one of the most extensive in southeastern Wisconsin. The large acreage makes it an important refuge for many species of birds and animals. The site also contains one of the largest Native American mounds in the state.
