Abstract

Peregrine falcon (Falco peregrinus) are listed as endangered species and Natural monument #323 in Korea, and this study examined the possibility of extinct of peregrine falcon in Jang Hang wetland near Han river using with the application of Population Viability Analysis (PVA) technique. In Jang Hang wetland areas population was monitored during 1999-2005 averaging 10.8 individuals and PVA analysis was done for the 5 years (2015-2020) using the average population size. Using the initial population was estimated 20% of extinct rate during the time. This estimation was quite low considering water pollution and loss of habitat. Also PVA only used population size lacking in other life history information. Nonetheless falcon population can be in risk of extinction if the current construction of crossovers in the river, cement bank are maintained. Long term information regarding life history needs essential.

매(Falco peregrinus)는 천연기념물 323호이며 멸종위기종으로 등재되어 있다. 본 연구는 한강의 장항습지에 서식하는 매의 멸종확률을 개체군변이분석을 통하여 시도하고자 한다. 장항습지는 개체군이 1999-2005년 동안 모니터링되었으며 평균 10.8 개체가 서식하는 것으로 조사되었으며, 개체군을 이용하여 향후 5년간(2015-2020) 변이분석을 실시하였다. 초기개체군을 이용하여 기간 동안 20%의 멸종확률이 예측되었으며, 이 확률은 지역의 수질오염과 서식지 손실을 고려하면 적은 것으로 나타났다. PVA는 개체군이 적고 다른 정보가 부족한 종에 대해 실시한다. 또한 매의 개체군은 댐의 보 및 콘크리트 제방 등을 고려하면 멸종의 확률이 증가될 것으로 사료된다. 장기적인 생활사 등을 고려한 연구가 필요하다.
