Cassville Bluffs State Natural Area

Cassville Bluffs

This 244-acre bluffland farm had served as a nature retreat for the Roe family for over 50 years. Cassville Bluffs State Natural Area was conserved through a joint effort by Mississippi Valley Conservancy and the Wisconsin DNR.  The Conservancy owns 190.6 acres and the Wisconsin DNR owns the remaining 53 acres (primarily the bluffland goat prairies and savannas along the River.)

In 2021, Conservancy staff and volunteers planted 2,000 oak trees at the top of the bluff in accordance with the land management plan for the property.

Cassville Bluffs contains a variety of habitats including upland and lowland oak-hickory forest as well as the rare savannas and goat prairies overlooking the Mississippi River.
