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 373,000 acres, Wisconsin's 673 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.

Serenity in the Northwoods

There is a moment early in my hike with DNR North-Central Field Ecologist Carly Lapin through Squirrel River Pines State Natural Area that we transcend into the sublime. We have paused so that Carly can show me - a total flora neophyte - how to tell a white pine from a red pine. Read the entire Natural Resources Foundation blog [exit DNR] for more.
