State Natural Areas Program

SNA Program logo

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. They also provide some of the last refuges for rare plants and animals.

It also is the largest — nearly 700 jewels sparkling across Wisconsin with the sole statutory purpose of saving for now and future generations a living record of diverse prairies, forests wetlands and other natural communities in the state. The summer issue of DNR's Natural Resources magazine examines the system 70 years after its creation by the state legislature and as climate change, invasive species, development and other threats challenge the sites.
