Calamus Swamp, located 1.5 miles west of Circleville, Ohio, was generously donated to Columbus Audubon by Percy May family members Ada May Burke and Sally V. May, who wish to see it preserved forever. Calamus Swamp is a beautiful, diverse and rare wetland that was dedicated as a Columbus Audubon Preserve on June 3, 2000. Calamus' 19 acres offer a unique glimpse into the glacial past that shaped Ohio's landscape. It is home to several distinct plant communities and numerous breeding birds, and is an appealing resting spot for birds migrating through the Scioto River corridor.
Columbus Audubon is proud to provide stewardship for Calamus Swamp. We have built a boardwalk and blind enabling greater accessibility without compromising the sensitive habitat. Our management plan provides for its ongoing care, guided by our Conservation Committee. We offer field trips to Calamus throughout the year.
