Join Columbus Audubon for a work day event on Saturday, April 10th from 10 AM until 2 PM at Calamus Swamp!  We'll be picking up trash, cleaning up signage, trimming and treating invasives, and laying down hardware cloth on slippery areas of the boardwalk.  Meet the Calamus Swamp parking lot - Calamus is located west of Circleville, just south of the junction of US-22 and Ohio-104.  For more information or to let us know you're coming, visit Contact Us  on the Columbus Audubon website, select Conservation from the dropdown menu, and leave us a message!
