Environmental Conservation Value Assessment Map (ECVAM) is one of the representative environmental assessment map aiming to prevent exploitation of land and to preserve natural environment outstanding areas. The result of ECVAM (2016) shows that the first class of the map occupies 47.1% of the whole territory. Thus, a more practical management of each class is needed for practical use in policy making. In this study, management plans for natural environment outstanding areas were evaluated by overlaying evaluation categories of ECVAM (habitat evaluation, connectivity, rarity) to classify into three classes: Strict nature reserve, core nature reserve, and buffer area. As a result, strict, core, and buffer region each occupied 1.16%, 5.64%, 17.39% of the territory.
Strict and core nature reserve located mostly in protection area such as national parks, recreational forest, and Baekdudaegan protection area. Regions near the cities or valley with high potential of development also located in the intersecting region of the three ECVAM categories. Therefore application of the evaluation result classified as strict, core, and buffer nature reserve areas is expected to contribute in preventing over exploitation of land and in improving land use management.
