Study on the National Park-centric National Ecological Network for the Enhancement of Biodiversity

Designating as many Protected Areas and networking them is essential for the enhancement of national biodiversity. In Korea, 20 National Parks occupy most large Proteced Area in total and have most abundant biodiversity. So, It needs to build National Ecological Network which focusing on National Parks. This study propose 5 ecological axis and 6 eco-region as a alternative of the current government policy. The Ecological Network is composed of Core Area, Buffer Zone and Corridor. In this study I suggest 50 km2 for the proper area criteria as a mountainous Core Area, and 1 km2 in inland wetland, and 10 km2 in coastal wetland. And also suggest 40~60 km as a proper distance between Core Area in good-managed area, and 20~30 km in more small or fragmented area. The proper outline-distance of Buffer Zone from the outline of Core Area is suggested as 2 km in mountainous area, and 1km in wetland area. The proper width of Corridor is suggested as 2~4 km in mountainous area, and 0.5~1 km at the river or stream. Based on the such criteria, I propose 38 Core area and 60 sub-Core Area in the 6 eco-regions of Korea. Among the 38 Core Area, 19 area is existing National Park and the other areas are needed new designation as the National Park.
