State Natural Areas Program

SNA 500th logo State Natural Areas (SNAs) protect outstanding examples of Wisconsin's native landscape of natural communities, significant geological formations and archeological sites. Wisconsin's 560 State Natural Areas encompassing 323,000 acres 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. In fact, more than 90% of the plants and 75% of the animals on Wisconsin's list of endangered and threatened species are protected on SNAs. Site protection is accomplished by several means, including land acquisition from willing sellers, donations, conservation easements, and cooperative agreements. Areas owned by other government agencies, educational institutions, and private conservation organizations are brought into the natural area system by formal agreements between the DNR and the landowner. The SNA Program owes much of its success to agreements with partners like The Nature Conservancy, USDA Forest Service, local Wisconsin land trusts, and county governments. Learn More...

Sedges, skunk cabbage, and witch hazel also grow along the flat-bottomed draw. As part of the Baraboo Hills landscape, this site contains important breeding and migratory habitat for many bird species. Learn more...
