초록

지리산국립공원에 멸종위기종인 반달가슴곰을 현장 내 복원하는 시도가 이루어지고 있으나 반달가슴곰의 최소 존속 개체군(MVP)의 유지에 필수적인 행동권과 최소 역동 면적(MDA)에 대한 자료는 거의 없는 상태이다. 본 연구에서는 2001년 지리산에 시험방사 된 바 있는 두 반달가슴곰의 위치 자료를 이용하여 곰의 이동 양상을 추적하고 두 가지 다른 방법으로 행동권을 산출하였다. 또한 곰에게 적합하다고 판정된 서식지와 실제 행동권의 크기와 위치를 비교하여 곰의 MVP보전 가능성을 평가하였다 곰의 출현빈도는 포장도로와 법정 탐방로의 밀도가 높아짐에 따라 급격히 감소하였다. 두 반달가슴곰의 행동권은 100% MCP 중간값이 376.85 $km^2$, 95% AK 중간값이 50.76 $km^2$이었고, 행동권 중첩면적은 각각 126.0 $km^2$와 3.99 $km^2$이었다. 핵심 활동 지역은 출입 통제 지역임에도 불구하고, 탐방로가 개방된 지역이 아니라 대부분 탐방로가 폐쇄된 곳에 밀집되어 있었다. 핵심 활동 지역과 적합 서식지의 불일치는 공원 내 도로를 통한 차량과 탐방객 유입의 결과인 것으로 판단된다. 결론적으로, 절멸위기종인 반달가슴곰의 현장 내 성공적 복원에는, 곰을 보호하고 곰의 행동권을 확보하여 MVP를 유지하기 위한 계획적 서식지 관리가 반드시 필요하다.

A project has recently begun to reintroduce endangered Asiatic black bears to the Jirisan National Park. However, information on home range that is necessary to maintain the Minimum Viable Population (MVP) of those bears does not exist. Based on point data of two bears that were released for trial in Jirisan in 2001, we identified the movement pattern of bears and estimated their home ranges with two different methods Finally, the possibility of conserving the MVP of bears was evaluated by comparing the location and size of the home range with habitats which have been found to be suitable for bears. The frequency of bears' appearance reduced drastically as road densities of both paved roads and legal trails increased. The midpoint of home ranges of the two bears was 376.85 $km^2$ and 50.76 $km^2$ based on 100% MCP (Minimum Convex Polygon) and 95% AK (Adaptive Kernel Home Range Method), respectively, with an overlapped area of 126.0 $km^2$ and 3.99 $km^2$ each. The core areas of their home ranges are located not in the no-entry zone, where major trails were open to the public - despite being designated as no -entry zone - but in areas where most trails were closed to the public. A discrepancy between core areas of home ranges and potentially suitable habitats suggests the effects of vehicles and tracking people through roads within the park. Thus, for the success of in situ conservation of endangered bears, well-planned management of habitats is needed to protect bears and to ensure the home ranges to support the MVP.
