Places We Protect

Use this map or browse the list below to explore the places we protect in Wisconsin.


Since our founding in 1960, The Nature Conservancy has protected more than 233,600 acres of land and water in some of Wisconsin’s most critical landscapes. These areas include the Baraboo Hills in Sauk and Columbia counties, the Door Peninsula, the forests of Northern Wisconsin, the Mukwonago River Watershed in southeast Wisconsin, and the Military Ridge Prairie Heritage Area in southwest Wisconsin.

The Nature Conservancy also owns and manages preserves in other locations around the state. Conservancy preserves are open to the public for recreational activities such as hiking, hunting, canoeing, cross-country skiing and wildlife-watching.

PLEASE NOTE: From September to January, gun and bow hunting for deer is allowed on many Conservancy preserves during DNR posted seasons. For safety and visibility we recommend that you wear blaze orange or neon pink clothing if you will be visiting one of the preserves where we allow hunting during this time period. Hunting is an important management tool that we use to keep the plants, animals and habitats at our preserves healthy and diverse.
