Conservation Easements
In addition to our five preserves, we hold conservation easements on 27 privately-owned properties across Sheboygan, Fond du Lac, Manitowoc, Calumet, and Kewaunee counties — protecting over 2,100 additional acres from development.
These voluntary legal agreements allow landowners to continue living on and using their property while permanently protecting its conservation values.
