摘要

Endangered species in heavily modified landscapes may be vulnerable to extinction if no conservation plan is implemented. The Suweon treefrog Dryophytes suweonensis is an endemic endangered species from the Korean Peninsula. In an attempt to conserve the species, a translocation plan was implemented in the city of Suwon. The receptor site was a specially modified island in a reservoir. Egg clutches were collected from four nearby sites, and were hatched and reared in a laboratory during 2015. One hundred and fifty froglets were released at the new site. In 2016, one year after the translocation, calling male D. suweonensis and newly hatched tadpoles and juveniles were recorded. Juveniles were seen until the last week before hibernation in autumn 2016. However, only a single male was recorded calling in 2017. The population was consequently considered functionally extinct. Failure of the translocation most likely arose from mismanagement of the vegetation surrounding the wetlands, and the resulting inability of the site to fulfil the ecological requirements of the species. The project allowed the development of rearing protocols for the species, and defined its ecological requirements.
