4. Shorebirds occuring in internationally important numbers at Yellow Sea sites (continued)
The following pages contain accounts for all 36 species that occur in internationally important numbers at one or more sites in the coastal regions of the Yellow Sea.
Subspecies Worldwide 3 (limosa, islandica and melanuroides); Yellow Sea 1 (melanuroides).
Distribution of L. l. melanuroides
Breeding: L. Baikal area, e. Mongolia, ne. China, Primorye, e. Yakutia and Kamchatka.
Non-breeding: Mainly coastal, but also inland. Bangladesh, Myanmar, Thailand, Indochina, s. China, se. Asia, New Guinea and n. Australia.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas and adjacent non-tidal wetlands. NM and SM Widespread and common; particularly numerous on nw. coast of South Korea, often in coastal rice fields and marshes. Numbers are probably underestimated, as this species often occurs on non-tidal wetlands which were generally less well surveyed than intertidal areas.
Movements: NM In South Korea, main passage occurs in May; in n. China, arrivals commence in late March (Y.X. Li in litt.), with numbers appearing to build up through April and then declining in early May. SM In South Korea, mainly during August. Birds from both nw. and e. Australia migrate through South Korea.
Significance of Yellow Sea: The Yellow Sea is important for this species and supports about 30% of the estimated flyway population on NM. The remainder of the population probably migrates through inland areas of China. Numbers may be lower during SM.
Key sites: 12 sites of international importance have been identified, 4 in China and 8 in South Korea; 7 of the sites are important during NM and 6 during SM (see site location maps below), with Asan Man being important during both NM and SM. Asan Man is of particular importance in supporting >10% of the estimated flyway population during NM, whilst 5% use the Mangyeung Gang Hagu during SM.
Status of key sites: The 3 Chinese sites and a small part of 1 site in South Korea (Dongjin Gang Hagu) are in Protected Areas. The Dongjin and Mangyeung estuaries are currently being reclaimed as part of the Saemangeum Reclamation Project.
Major gaps in knowledge: Usage of coastal non-tidal wetlands in w. South Korea. Incomplete geographical and temporal coverage in China, especially of coastal non-tidal wetlands. No information from North Korea.
EAAF POPULATION ESTIMATE: 160 000
Status: Passage migrant
Estimated minimum numbers:
NM: South Korea: 31 000; China: 17 000.
SM: South Korea: 17 000.
INTERNATIONALLY IMPORTANT SITES (and Protected Area status)
South Korea: 8 (part of 1)
