The Arkansas Ecological Services Field Office and Arkansas State Parks partnered to build 11 gates at Devil’s Den State Park on crevices that act as hibernacula for Ozark big-eared bats, Indiana bats, tri-colored bats and big brown bats. Prior to gating the colonies experienced extensive human disturbance of hibernating bats. The first-year post gating, Ozark big-eared bat use of gated crevices increased by over 80%.
