State Natural Area

State natural areas (SNAs) protect outstanding examples of Wisconsin’s native landscape of natural communities, significant geological formations and archeological sites. Encompassing 406,000 acres on lands owned by the state and its many partners, including land trusts, local and county governments, and private citizens, Wisconsin’s natural areas are valuable for research and educational use, the preservation of genetic and biological diversity and for providing benchmarks for determining the impact of use on managed lands.
