Ecologically important area for waterbirds in Yellow Sea
Yellow sea is one of the hotspot in the Asia Pacific flyway of waterbirds(Shorebirds flyway, Anatidae flyway, Crane flyway). Existing information and data of waterbirds in Yellow Sea were reviewed. Ecologically important area (EIA) for bird habitat was identified as the potential priority area for developing protected area. Adopted common criteria was applied to identify EIA in Yellow sea between China and Korea (representative species, endemism and unique species assemblages, threatened and/or protected spp. Ramsar criterion). Indicator species under each criterion was selected and potential priority area was delineated. Red-crowned cranes(Grus japonensis), Hooded cranes(Grus monacha), White-naped cranes(Grus vipio), Black-faced spoonbill(Platalea minor), Oriental white stork(Ciconia boyciana), Chinese egret(Egretta eulophotes), Baikal teal(Anas formosa), Whooper swan(Cygnus Cygnus), Saunders’s gull(Laurs saundersi), Oystercatcher (Haematopus ostralegus) were selected for representative species. Baikal teal(Anas formosa) was selected locally endemic and unique species assemblages as over 90% of its world estimated population are regularly aggregated in reclaimed area Korea in wintering period. Shuangtaihe estuary, Beidaihe, Yellow River delta, Yancheng coastal region (in China), Han river estuary, Tongjin river estuary, Cheonsu bay, Gyonggi bay (in Korea) were EIA area in Yellow sea. Potential priority areas (PPAs) were identified by indicator species, which were forwards to reviewing multi-disciplinary with cross-taxonomic groups such as marine mammals, coastal plant, algae, fisheries and invertebrates. And current existing protected areas in coastal and marine area are overlapped with PPAs, which provide a knowledge gap of protected and management implication.
