Ⅰ. Background and Aims of Research
o Before the 1980s, agricultural areas were widely distributed in the lower part and estuary areas of the Han River. The lower part of the Han River and its estuary are an intermediate stopover site for migratory birds and is one of important bird sanctuaries in Korea.
o The lower part and estuary areas of the Han River have been designated and managed as legally protected areas such as cultural heritage protection areas and wetland protection areas. It is also a space that requires continuous protection and preservation.
o In this study, land use changes in the lower part and estuary areas of the Han River since the 1980s were analyzed. In addition, qualitative changes in wildlife habitats resulting from the development activities were analyzed by period.
o Through the analysis of land use change simulation, future land use in the lower part of the Han River and its estuary was predicted. The qualitative changes in wildlife habitats were also simulated.
Ⅱ. Migratory Bird Census Results in the Lower Part of the Han River and Its Estuary
o The number of bird species identified in the migratory bird census in the lower part of the Han River and its estuary was confirmed to be about 70 species. About 50 species appear in the lower area of the Han River and more than 60 species appear in the estuary of the Han River.
Ⅲ. Land Use Changes in the Lower Part of the Han River and Its Estuary
1. Land use change simulation through scenario analysis
o Table 1 shows all nine scenarios applied to the InVEST Scenario Generator analysis to predict
