Abstract
Habitat loss by industrialization, urbanization, and poaching reduced the population of Asiatic black bear (Ursus thibetabus ussuricus) population in South Korea in the late 20th Century. In the early 2000s, the Korean Government had begun a restoration project of Asiatic black bear. In 2017, a bear was found in Mt. Sudosan, Gimcheon, Gyeongsangbuk-do, approximately 80 km from Mt. Jirisan where the bear was first released. Genetic analysis confirmed that this bear was one of the Jirisan bear population, estimating that this bear escaped from its habitat. After trapping this bear in Mt. Sudosan, it was rereleased again in Mt. Jirisan, but this bear moved again to Mt. Sudosan. After 2nd trapping and releasing, this bear came back to Mt. Sudosan. In Mt. Sudosan, this bear covered a greater distance and moved more as compared to other Asiatic black bear in Mt. Jirisan. Today, this bear has its home range within Mt. Sudosan area after the third release, estimating that this bear is stable and active in this area. Our findings are the first case showing the interesting pattern of repetitive disperse activities and habitat expansion of Asiatic black bear. The results of this case are valuable information that can be used for wildlife conservation and restoration of endangered wildlife.
