초록

지리산국립공원 반달가슴곰은 2004년부터 러시아 연해주, 북한, 중국 동북부 일대와 서식지외 보전기관인 서울대공 원에서의 재도입을 통해 복원사업을 진행하고 있다. 본 연구의 목적은 배설물을 통해 식이물을 분석하여 반달가슴곰의 먹이습성, 지리산국립공원에서의 먹이 자원 환경을 파악하기 위함이다. 2005년부터 2013년 사이에 무선 위치 모니터링 이 가능한 반달가슴곰 배설물 78점을 채집하여 먹이원을 분석한 결과 상대출현빈도는 식물이 77%로 가장 높게 나타났 고, 곤충 12.8%, 포유류 5.6%, 기타 3.6%, 조류 0.5%, 절지동물문 0.5%의 순이었다. 또한 수집한 배설물 중 건중량을 측정한 52점 대상으로 먹이 비(ratio)를 분석한 결과 식물이 91.2%로 가장 높게 나타났으며, 포유류 3.6%, 곤충류 1.0%, 기타 4.2%의 순이었다. 배설물을 통한 먹이원 분석 연구 결과 지리산에 서식하는 반달가슴곰은 잡식성이며, 동물성 먹이보다 식물성 먹이가 주 먹이원인 것으로 확인할 수 있었다.

Since 2004, Asiatic Black Bear of the Jirisan National Park is subjected to the restoration project through the re-introduction by the Maritime Province of Siberia in Russia, North Korea, Northeastern part of China and Seoul Grand Park. The purpose of this study is to analyze diets with scat to identify Asiatic Black Bear’s feeding habit and eating resources environment in the Jirisan National Park. 78 scats of Asiatic Black Bears were observed during the field studies of radio telemetry-marked bears and by chance in the Jrisan National Park, from 2005 to 2013. The relative frequency of occurrence demonstrated that the plants comprised the highest with 77%, followed by insects with 12.8%, mammals with 5.6%, birds with 0.5%, arthropoda with 0.5%, and others with 3.6%. Also, 52 scats among the collected scats that were measured for the ratio of food were subjected to dry weight, and plants were the highest with 91.2%, followed by mammals with 3.6%, insects with 1.0% and others with 4.2% in the order mentioned. Asiatic Black Bear’s feed research demonstrated that the Asiatic Black Bear at Jirisan is omnivorous and that the vegetable food is the main feed instead of animal feed.
