Une étude sur le rôle des habitats des aménagements de zones d'estran pour les oiseaux migrateurs d'hiver en Corée. This study has been carried out to evaluate the habitat role for migratory birds of a tidal reclamation area in comparison with a river estuary in Korea. It also includes the contribution effect of the contract on the optional Choice of Paddy Field Management (CPFM) program to sustain biodiversity of winter migrants in Korea. The CPFM program has been practiced to attract winter migratory birds in cooperation with farmers who spread rice straw, cultivate barley and provide shallow flooding paddy during the winter season in various reclaimed areas. The study result shows that a large number of winter migratory birds visited the tidal reclamation areas and the reason is thought to be that wave intrusion was prevented by the sea dike and water level changes in the lake are less than tidal level changes in the estuary, as well as the irrigated paddy field supply of food and shelter for birds in the reclaimed area. In the tidal reclamation area, the dominant species are waterfowl such as geese and ducks, while waders, shore birds and other small birds declined after reclamation in the area, as the freshwater lakes are rather deeper than coastal shore lines and thus do not attract them. In conclusion, tidal areas with large paddy fields and freshwater lakes have not only led to an increase in food production but have attracted winter migrants supported by farmers and government; however, more effort will be needed to provide habitats for rare and distinctive birds in the reclamation area. © 2013 John Wiley & Sons, Ltd.
