2004년 10월부터 2006년 12월까지 지리산에 방사한 반달가슴곰 7개체를 무선추적하여 연간 행동권 크기를 분석한 결과, 95% MCP에서 반달가슴곰 암컷은 71.66km2, 수컷은 90.20km2로 분석되었다. 계절별 행동권 크기는 암컷곰이 봄 19.8km2, 여름 30.48km2, 가을 22.63km2, 겨울 0.22km2이었고, 수컷곰은 봄 33.47km2, 여름 20.26km2, 가을 23.23km2, 겨울 0.78km2이었다(F=4.193, P〈0.05). 반달가슴곰의 행동권역중 약 38% 정도가 중첩되었고, 암컷간 12.5%, 수컷간 22.4% 정도가 중첩되었다. 서식지 평균 해발고도는 봄 744±236m, 여름 682±253m, 가을 937±218m, 겨울 975±137m로 분석되었다(F=8.526, P〈0.001). 반달가슴곰의 행동권 크기와 위치는 주로 먹이의 분포와 생산량과 밀접한 관계가 있으며, 계절별 서식 환경특성, 연령 등에 따라서도 차이가 있음을 알 수 있었다.
The studies of seven individuals of Asiatic black bears were carried out with radio telemetry from October 2004 to December 2006 in Jirisan National Park. They were attached radio-transmitter and calculated by the 95%MCP and fixed kernel method(95%, 50%). As a result, Mean annual home ranges for female and male asiatic black bears were 71.66km2 and 90.20km2. The seasonal home ranges were calculated 19.81km2 for females and 33.47km2 for males in spring, 30.48km2 for females and 20.26km2 for males in summer, 22.63km2 for females and 23.23km2 for males in autumn and 0.22km2 for females and 0.78km2 for males in winter(F=4.193, P〈0.05). The degree of home range overlapped 38%, 12.5% among females, 22.4% among males. Mean elevation of seven bears was 744±236m in spring, 682±253m in summer, 937±218m in fall and 975±137m in winter(F=8.526, P〈0.001). It is assumed that home range sizes and location were closely correlated to environmental characteristics of the habitats and the seasonal variation of home-range was related to distribution of food sources.
