The National Natural Landmarks (NNLs) in Wisconsin include 18 of the almost 600 such landmarks in the United States.[1] They cover areas of geological, biological and historical importance, and include dune and swales, swamps, bogs, and virgin forests.[1] Several of the sites provide habitat for rare or endangered plant and animal species. The Driftless Area in southwest Wisconsin is known for its rare species, especially in the Baraboo Range.[1] Owners include private individuals, Native American tribes, and several county, state and federal agencies.[1] These landmarks were designed between 1967 and 1987.[1] They vary in size between 44 and 53,531 acres (18 and 21,663 hectares).[1]
The National Natural Landmarks Program is administered by the National Park Service, a branch of the Department of the Interior. The National Park Service determines which properties meet NNL criteria and, after notifying the owners, makes nomination recommendations. The Secretary of the Interior reviews nominations and, based on a set of predetermined criteria, makes a decision on NNL designation or a determination of eligibility for designation. Both public and privately owned properties can be designated as NNLs. Owners may object to the nomination of the property as a NNL.[2] This designation provides indirect, partial protection of the historic integrity of the properties via tax incentives, grants, monitoring of threats, and other means.[3]

The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall.

The Aldo Leopold Shack and Farm is a historic farm on Levee Road in rural Sauk County, Wisconsin, United States. The property was acquired in the 1930s as a family summer retreat by the noted conservationist and writer Aldo Leopold and is the landscape that inspired his conservation ethic and the writing of his best-known work, A Sand County Almanac. The property is now owned and managed by the Aldo Leopold Foundation, which provides tours and other educational programs on the property and the adjacent visitors center. It was listed on the National Register of Historic Places in 1978 and was designated a National Historic Landmark in 2009.
