Homing behavior is a fundamental ecological trait influencing site fidelity and the success of translocation programs for endangered species. This study evaluated the homing ability and effective homing range of the Reeves’ turtle (Mauremys reevesii), a Class II Endangered Wildlife species and a Natural Monument in South Korea. Six adult turtles were captured from reservoirs in Gurye-gun, attached with GPS transmitters, and artificially displaced to terrestrial release sites at distances ranging from 200 to 600 m from their original habitats. Monitoring from May 2023 to July 2024 revealed a distance-dependent homing response: individuals displaced by 200 m and one of two displaced by 300 m successfully returned to their original reservoirs. However, all turtles displaced by distances greater than 300 m (400~600 m) failed to return. These results suggest that while M. reevesii possesses homing instincts, its effective homing range on land is relatively limited compared to other freshwater turtles. This study provides the first empirical evidence of the spatial limits of homing in Korean M. reevesii populations. Technical challenges, such as signal loss due to mud accumulation on solar-powered tags in wetland environments, were also identified as a factor to consider in future telemetry studies. For successful translocation, we recommend selecting release sites within 300 m of core habitats to maximize settlement success.
