Abstract

The number of protected areas has been steadily increased in Korea to achieve Aichi Target 11, and there are studies on potential protected areas that required additional designation. However, there has been an insufficient assessment of the complementarity of protected areas to conserve biodiversity effectively. This study identified the potential habitat areas using the species distribution model for plant species from the 3rd National Ecosystem Survey and compared the plant species abundance in the existing protected area and the potential protected areas using the similarity indices, such as the Jaccard index, Sorenson index, and Bray-Curtis index. As a result, we found that the complementarity of the existing protected areas and most potential protected areas were low, leading to the preservation of similar plant species. Only the buffer zone for Korea National Arboretum had high complementarity and thus is important to conserve some species with the other protected areas. This study confirmed that it was necessary to select additional protected areas outside the existing or potential protected areas to protect plant species with a low inclusion ratio of potential habitats within the protected area. This study is significant because it identified the ecological representativeness of each protected area to examine if the individual protected area can conserve unique and various species and proposed a method of finding candidate areas for additional conservation spatially. The findings of this study can be a valuable reference for the qualitative improvement of protected areas through the complementarity assessments, including animals and the effectiveness assessment study of protected areas using the National Ecosystem Survey data in the future.

아이치 생물다양성 목표11을 달성하기 위하여, 국내 보호지역은 양적으로 꾸준히 증가되어왔으며, 추가 지정이 필요한 잠재 보호지역에 대한 연구도 진행되어왔다. 하지만 효과적인 생물다양성 보전을 위한 보호지역의 상보성에 대한 평가는 미흡하다. 본 연구에서는 제3차 전국자연환경조사의 식물종을 대상으로 종분포모형을 이용하여 잠재서식지역을 도출하고, 기존 보호지역과 잠재보호지역 내 잠재서식지역이 포함되는 종의 풍부도를 유사도 지수인 Jaccard, Sorenson, Bray-curtis를 이용하여 비교분석하였다. 연구결과로 기존 보호지역과 잠재보호지역 대부분이 상보성이 낮아 유사한 식물종을 보전하는 것으로 나타났다. 국립수목원 완충지역이 상보성이 높아 보호지역으로서의 가치가 높다고 할 수 있다. 잠재서식지역이 포함되는 경우가 적은 식물종을 보호하기 위해서는 기존 또는 잠재 보호지역 외 지역에 추가로 보호지역을 선정할 필요가 있음을 확인할 수 있었다. 본 연구는 개별 보호지역이 보호지역으로서 고유한 생태계 또는 생물종 보전이 가능한지 각 보호지역의 생태적 대표성을 확인하고, 공간적으로 추가 보호가 필요한 지역을 탐색하는 방법을 제안했다는 점에서 의의가 있으며, 향후 동물종까지 포함한 상보성 평가를 통한 보호지역의 질적 개선과 계속적으로 조사되는 전국자연환경조사 자료를 이용한 보호지역의 효과성평가 연구 등으로 발전시킬 수 있을 것으로 판단된다.
