We investigated species, ecological pathway type, and mammal size using two eco-tunnels from trail-camera data. The analyses of the camera data showed that 12 mammalian species from 8 families of 5 orders used Jin-gogae eco-corridor (bridge type) and 14 mammalian species from 9 family 5 orders were found at Odaesan eco-corridor (tunnel type). At both eco-corridors, water deer used eco-corridor most frequently, and then secondly racoon dog did. The analyses by mammal size (small, medium, and large) showed that large-sized mammals were found in high ratio at the bridge type of the eco-corridors. In case of medium-sized mammals, utilization ratio of the tunnel-typed corridor was 42%, whereas that of the bridge-typed corridor was 24%, showing 1.8 times higher usage.
