Abstract

To suggest effective ways of the management of reptiles in Korea national parks, we applied PIT (passive integrated transponder) tag and radio telemetry research methods in the monitoring of reptiles in Odaesan and Woraksan national parks. We implanted PIT tags into 137 snakes (six species) captured in both the national parks between March 2006 and October 2008 and also radio-tracked two Korean rat snakes (Elaphe schrenckii anomala) from September 2007 to November 2008 in the Woraksan national park. Of total 137 snakes which we had inserted the PIT tag, 17 snakes (12.40%) were recaptured. Based on the PIT tag data of the recapture, we successfully obtained the annual growth rate of Korean cat snakes (Elaphe dione) and Red-tongue pit-viper (Gloydius ussuriensis). Home range of the Korean rat snakes based on the data of radiotracking was estimated as 389,600$m^2$ (MCP: Minimum convex polygon) and 471,800$m^2$ (Kernel 95%) for males and 162,500$m^2$ and 208,700$m^2$ for females. These results suggest that if we apply PIT tag and radio telemetry research methods to manage reptiles in Korea national parks, it could greatly increase our understanding about their basic ecology and as the result, it could allow us to develop better management and conservation ways of reptiles in Korea national parks.

본 연구는 PIT tag (passive integrated transponder)과 무선추적법(radio telemetry)을 오대산국립공원과 월악산국립공원에 서식하고 있는 파충류에 적용한 후, 이를 평가하여 효과적으로 국립공원 내 파충류 자원관리 방안을 모색하기 위하여 수행되었다. PIT tag은 현재까지 알려진 파충류 개체표시법 중에서 가장 효과적인 방법으로 2006년 3월부터 2008년 10월까지 오대산국립공원과 월악산국립공원의 조사지역에 출현한 모든 137마리의 뱀류를 대상으로 적용하였다. 무선추적 연구는 월악산국립공원에서 서식하고 있는 황구렁이(Elaphe schrenckii anomala) 2마리를 대상으로 2007년 9월부터 2008년 11월까지 실시하였다. 연구결과, 두 곳의 국립공원 지역에서 연구기간 동안 17마리가 재 포획되어 평균 12.40%의 재포획률을 보였으며, 재 포획된 개체들의 자료를 통하여 누룩뱀 (Elaphe dione)과 쇠살모사 (Gloydius ussuriensis) 성체의 SVL 증가를 성공적으로 확인하였다. 무선추적을 통하여 확인된 황구렁이 수컷의 행동권 면적은 MCP=389,600 $m^2$, Kernel 95%=471,800 $m^2$, 암컷은 MCP=162,500 $m^2$, Kernel 95%=208,700 $m^2$인 것으로 확인되었다. 국립공원 내에서 보호와 관리가 필요한 종 혹은 멸종위기대상 종인 파충류를 대상으로 PIT tag과 무선추적을 적용한다면 공원 내 파충류의 효율적인 관리 및 보존방안을 마련하는 데 중요한 기초자료를 제공할 수 있을 것으로 생각된다.
