Stream restoration projects have become threats to riparian ecosystem in Rep. of korea. Riparian wildlife becomes isolated and the animals are often experience difficulties in crossing riparian corridors. The purposes of this study is to select suitable wildlife passages for wild animals crossing ri...

수변지역은 어떤 역할을 하는가? | 하천과 육상의 경계에 있는 수변지역은 지리적 특성으로 인해 독특한 생태계를 구성하고 있으며, 높은 생물다양성을 보인다. 특히 이 지역은 포유류, 조류, 양서 파충류를 비롯한 많은 생물의 서식공간으로서 역할 뿐만 아니라 이동공간으로도 기여함으로써, 인근 생태계와 네트워크를 구성하는 중요한 역할을 한다. 우리나라 에서는 1960년대부터 치수와 이수를 목적으로 한 하천 종합개발계획을 수립한 결과 보, 제방, 하구둑 등 많은 구조물의 건설되었으며, 수변지역은 둔치와 같은 친수 공간을 조성하였다. | |
서식지 적합성 평가란 무엇인가? | 선진국에서는 이미 1970년대 이후 자연환경 관리정책에 생물종의 서식지 적합성 평가에 따른 보전지역 설정 및 복원을 위한 대상지 선정을 반영하고 있다(Lee and Song, 2009). 서식지 적합성 평가는 환경변수를 이용하여 야생동물의 서식에 적합한 환경조건을 분석하는 것으로 과거에는 GAP(Gap Analysis Program)이나 서식지적합성 지수(Habitat Suitability Index)와 같은 모형을 이용하였으나 정확도 부분에서는 한계가 있었다. 최근에는 종분포도와 통계 기법을 활용하여 다양한 종분포모형이 개발되었으며, 자료의 종류(출현/비출현자료, 출현자료만)에 따라 적합한 모형을 적용 중이다(Kwon, 2011;Seo et al. | |
서식지의 파편화와 단절은 어떤 결과를 일으키는가? | 서식지의 파편화와 단절은 생물다양성 감소를 야기 하며, 일부 지역에서는 메타개체군 절멸로 이어진다 (Park et al., 2012). |
