Abstract

Narrow-mouth frog (Kaloula borealis) is the only amphibian species of genus Kaloula living in South Korea. They are designated and managed as endangered class II wildlife by the Ministry of Environment, Korea. Therefore, there is a desperate need of a habitat restoration study to prevent the extinction of narrow-mouth frog. This study is primarily for the purpose of presenting the direction and practical applications to restore damaged narrow-mouth frog habitats or to suggest alternative habitat options. The habitat suitability index (HSI) of narrow-mouth frog was applied to the research area in Mokpo City of Jeollanam-do Province, in order to present a new narrow-mouth frog habitat. We analyzed the research area based on historical contexts, ecological environment, ecology, and habitat requirements. The research area was divided into the core, buffer, and transition zones according to UNESCO MAB (Man and Biosphere) to establish local land-use plans. As for the foundation of the plan, we divided the habitat composition of the core, where narrow-mouth frog live in, into wetland (spawning area), grassland (shelter and feeding grounds), and forestland (feeding ground). We had a comparative analysis of habitat suitability in pre and post planning of narrow-mouth frog habitat restoration. For the validation study of habitat restoration plans, the future research should be on the composition of test-bed, continuous monitoring, and scientific habitat maintenance.

맹꽁이는 Kaloula 속에 속하는 양서류로는 우리나라에서 유일하게 한 종이 서식하고 있으며 멸종위기야생생물 II 급으로 지정, 관리하고 있어 맹꽁이의 절멸 방지를 위해서는 맹꽁이에 대한 서식처 복원 연구가 절실히 필요하다. 본 연구는 훼손된 맹꽁이 서식처 복원이나 대체서식지와 같은 새로운 맹꽁이 서식처 복원 시 바람직한 생태적 복원 방향을 제시하기 위하여 연구 대상지인 전라남도 목포시에 맹꽁이 서식처 적합성 지수 (HSI)를 활용 및 실제 적용하여 맹꽁이 서식처 복원 계획을 제시하는 것을 주된 목적으로 하였다. 연구대상지의 역사적 맥락, 생태기반환경, 생태환경, 맹꽁이의 서식처 요구 조건 등을 분석한 후 UNESCO MAB (Man and Biosphere) 공간구획에 따라 연구 대상지를 핵심, 완충, 전이지역으로 토지이용 계획을 수립하였다. 기본계획으로 맹꽁이 서식처인 핵심지역에 대한 구체적인 맹꽁이 서식처 조성방안을 습지 (산란처), 초지 (은신처 및 먹이터), 수림대 (먹이터)로 구분하여 제시하고 서식처 계획 전, 후의 맹꽁이 서식처 적합도를 비교 평가하였다. 향후 맹꽁이 서식처 복원 계획에 따른 검증 연구로 테스트베드 (test-bed) 조성, 지속적인 모니터링, 과학적인 서식처 유지 관리에 대한 연구가 이루어져야 한다.
