The Empire-Sauk Chapter is active in a varied landscape with prairies and savannas in the Driftless area, and across the terminal moraine with prairies on glacial till and on drumlins. We are involved with many aspects of prairie conservation, protecting and restoring prairies and savannas, offering naturalist led field trips and supporting citizen science and research. We welcome volunteers in all aspects of our activities.

Learn more by visiting About our chapter and Sites and projects (this page includes a map of sites) web pages. 

The Empire-Sauk chapter covers Columbia, Dane, Sauk, and eastern Iowa Counties in Wisconsin.
