Identifying high-priority conservation areas for endangered waterbirds using a flagship species in the Korean DMZ

Abstract

The Hangang River and Imjingang River estuaries in Korea are part of the main transit route for many migratory birds that use the East Asia-Pacific flyway. Despite the global importance of this area as a seasonal bird stopover site and resting area, conservation areas have not been established in this area based on ecological properties. This study aimed to examine the umbrella effect of the white-naped crane (Antigone vipio), which is one of the best-known flagship species in East Asia, and to determine the effectiveness of establishing a conservation plan in the western DMZ based on the distribution of white-naped cranes. Species distribution modeling was performed for the white-naped crane; other threatened waterbirds wintering in the western DMZ; Group 1, including species with ecological traits similar to those of the white-naped crane; and Group 2, including species with ecological traits different from those of the white-naped crane. The modeling was based on field survey data from a citizen science project, and a systematic conservation planning approach was adopted for each species group. The results showed no significant differences between the plan for the target species and the plans for the other species groups, indicating that protecting white-naped cranes habitat can also protect the habitat of other threatened waterbirds.
