TheNational Natural Landmarks (NNLs) inWisconsin include 18 of the almost 600 such landmarks in theUnited States.[1] They cover areas of geological, biological and historical importance, and include dune and swales, swamps, bogs, andvirgin forests.[1] Several of the sites provide habitat for rare or endangered plant and animal species. TheDriftless Area in southwest Wisconsin is known for its rare species, especially in theBaraboo 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 theNational Park Service, a branch of theDepartment of the Interior. The National Park Service determines which properties meet NNL criteria and, after notifying the owners, makes nomination recommendations. TheSecretary 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]
