Abstract

In order to prevent the fragmentation of animal habitat due to road construction, the most widely applied solution is building animal passes worldwide. In Korea, animal passes were introduced in the early 2000s, and through trial and error, the national guidelines for them and their design standards were published in 2010. These were criticized by politicians because of their relative inefficiency considering their high construction cost and their lack of animal usage. This study investigated the extent to which animals used the facilities. For this study, two types of animal passes, eco-bridges and ecoducts, were considered and the test sites were chosen from the Baekdu Mountains. The animal usage data was captured using infra-red CCTV cameras. The results showed that various types of animals used eco-bridges and ecoducts. Interestingly various types of birds were captured by cameras and endangered animals were also in them. The season, weather, and their surrounded vegetation also had effects on their usages. The infrared CCTV allowed detailed captures of animals but the electricity shortage was one disadvantage. During the last decades, a number of eco-bridges were constructed throughout the country and now we need to focus on their monitoring and maintenance for their successful efficiency and application.

도로건설로 인한 동물서식지의 단절을 막기 위해서 전 세계에서 가장 보편적으로 많이 설치되는 것이 생태통로이다. 한국에서는 2000년대 초반부터 생태통로가 도입되기 시작했고, 시행착오를 거쳐서 2010년 생태통로를 위한 국가기준과 설계기준이 만들어졌다. 최근 이러한 생태통로가 건설비용이 높은 반면, 동물이용이 저조하다는 이유로 비판을 받고 있다. 본 연구는 어떤 동물이 얼마만큼 이러한 시설을 이용하는지 조사하려고 하였다. 이를 위해서 백두대간에서 가장 전형적인 육교형과 터널형 생태통로를 선정하였고 적외선 CCTV를 설치해서 모니터링하였다. 그 결과, 비판과는 달리 다양한 동물이 이용하는 것으로 나타났다. 흥미롭게도 다양한 조류가 관찰되었고 보호동물종도 관찰되었다. 동물이용은 계절, 날씨 및 주변 식생이 영향을 미치는 것으로 나타났다. 적외선 카메라를 사용하였을 때 동물을 자세하게 촬영할 수 있었으나 전기소모량이 많은 것이 단점이다. 지난 10년간 전국적으로 많은 생태통로가 설치되었다. 이제 시설의 효율성과 성공적인 활용을 위해서 모니터링과 유지관리가 필요하다.
