Analysis of Area Changes in Ecological and Natural Map Grades between 2007 and 2025: Focusing on Map Sheets Covering Border Region

This study analyzed changes in the grades of the Ecological and Natural Map across 36 map sheets, including border regions, between 2007 and 2025. Variations in area by grade were influenced by the survey data available at the time of map compilation, differences in evaluation criteria, and improvements in survey precision. In particular, border regions exhibited a marked increase in separately managed zones, reflecting the application of conservation-oriented policies from an ecological perspective. These findings can serve as a basis for formulating conservation and management policies for border regions and for developing ecosystem management strategies tailored to local environmental conditions.
