This study analyzed the spatiotemporal changes of wetlands in the Saemangeum watershed by comparing topographic maps from the 1918 and 2015, and analyzed the changes in connectivity among wetland habitats through wetland network analysis. The results showed that wetlands that were widely distributed around rivers and estuaries in the past have been largely lost, while artificial reservoirs around agricultural lands have increased in the upper reaches. Although the wetland area including artificial reservoirs increased slightly, most of the natural wetlands around the river channel were lost, and the dominant wetland type and distribution in the watershed changed significantly. In particular, the connectivity between coastal wetlands and inland wetlands decreased and the connectivity around small reservoirs increased, resulting in a disconnection of the wetland network structure. These changes may have a negative impact on the movement of wetland organisms and the circulation of materials, and further affecting the stability of the Saemangeum watershed ecosystem. In order to restore wetland biodiversity in the Saemangeum watershed, it is necessary to restore the past wetland areas and monitor the remaining wetlands. It is urgent to establish resilient governance and develop a restoration plan to maintain connectivity among marine, freshwater, and terrestrial ecosystems.
