Preparation an Ecological Map Using Data from the Third Survey on National Environment

In this study, we created a map to present the results of the third survey on national environment, following the ecological and natural map guidelines established by law. For the terrestrial areas of the Republic of Korea, we conducted three assessments, vegetation, landform, and endangered species, at a national scale. The results yielded an ecological map covering 99,138.5 km<sup>2</sup>. The map showed the area distribution of different grades as follows: 11.3% for grade 1, 31.4% for grade 2, and 57.3% for grade 3. Specifically, within grade 1, vegetation covered 90.5% of the area, endangered species covered 9.7%, and landform covered 1.3% (including overlapping areas). This map provides detailed information including habitats of endangered species that were previously inaccessible to the public. Additionally, it offers insights into management areas with separately managed zone that could not be identified in existing ecological and natural maps.
