Black Earth Rettenmund Prairie was once part of the William Rettenmund farm, and remarkably, it was never plowed, although it experienced some grazing. William Rettenmund himself played a crucial role in its preservation, safeguarding the prairie for over 40 years and allowing conservationists to study and manage it, including conducting controlled burns. Formal efforts to protect the prairie began in the early 1980s. The Nature Conservancy acquired the property in 1986 with financial support from the Madison Audubon Society, and it was officially dedicated as a State Natural Area that same year. Management of the prairie was later transferred to The Prairie Enthusiasts in 2003, who took full ownership in 2007. The site holds historical significance, having been used as an outdoor classroom by renowned Ecologist John Curtis, contributing to his classic work, "Vegetation of Wisconsin."
