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 over 380,000 acres, Wisconsin's 681 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.

The forefather of the State Natural Areas System

Cliff Germain

Cliff Germain walks the talk of preserving unique and pristine properties.

"Without Cliff, the State Natural Areas system wouldn’t be what it is today." Germain’s first jobs with DNR’s predecessor agency, the Wisconsin Conservation Department, were as a wildlife researcher and then game manager. He had joined the Conservation Department in 1949 after serving in the U.S. Army in World War II and earning a zoology degree at the University of Wisconsin-Madison. There, he studied with conservation giants including Aldo Leopold, ecologist John Curtis and leading plant taxonomist Norman Fassett. They inspired him and instilled in him the land ethic and the importance of Leopold’s admonition that “to keep every cog and wheel is the first precaution of intelligent tinkering.”
