Daughmer Prairie is a small remnant of the once vast Sandusky Plains that was composed of over 200,000 acres of tall grass prairie and oak savannah, covering parts of three present-day Ohio counties. There are only 74 acres remaining of the Sandusky Plains, and Daughmer Savannah is one of the largest remaining tracts.

Located on the Daughmer Bur Oak Prairie Savannah State Nature Preserve are threatened Bicknell’s sedge and the potentially threatened wheat sedge and flat stemmed spike-rush, as well as its namesake, the towering majestic bur oaks that are over 200 years old. This is one of the best remaining oak savannahs in the United States.

The efforts of five generations of Hazel (White) Daughmer’s family have kept the prairie habitat to be maintained through low-intensity grazing and the occasional periodic controlled burns.

This preserve is open to the public for low impact recreation including hiking, birdwatching, and research by permit only. While owned by the Ohio Department of Natural Resources (ODNR), it is managed by the Crawford Park District. ODNR was able to purchase this State Nature Preserve in 2010 with funds from the Division of Natural Areas and Preserves Tax Check-Off program.

Daughmer Bur Oak Prairie Savannah State Nature Preserve is located in southern Crawford County, eight miles southwest of Bucyrus, at the intersection of Scioto Chapel Road and Marion-Mercer Road.
