4.4 Species accounts (continued)

4.4.15 Asian Dowitcher Limnodromus semipalmatus

Subspecies None; entire global population confined to the EAAF.

Distribution

Breeding: s. Siberia, n. Mongolia and ne. China.

Non-breeding: Coastal. se. Asia, New Guinea and n. Australia; main stronghold is probably e. and se. Sumatra.

Usage and importance of Yellow Sea

Occurrence: Intertidal areas and adjacent non-tidal wetlands. NM and SM n. from Chang Jiang Estuary to n. Liaodong Wan, with major concentrations in Bohai Wan and Yancheng NNR/Dongsha region. Absent from South Korea. Significant undercounting may have occurred because of the difficulty of separating this species from the godwits.

Movements: The e. Chinese coastline is the e. boundary of both NM and SM routes. Whilst good numbers have been reported from Chinese coastal sites, it is probable that many birds migrate along inland routes through China.

Significance of Yellow Sea: The Yellow Sea is important for this near-threatened species as it supports about 40% of the estimated flyway population during NM. Numbers may be similar on SM.

Key sites: 4 sites of international importance have been identified, all in China; all sites are important during NM and 3 during SM (see site location maps below). Dong Sha supports >5% of the estimated flyway population during SM.

Status of key sites: 1 Chinese site is in a Protected Area.

Major gaps in knowledge: Incomplete geographical and temporal information from China, particularly Bohai Wan and the Jiangsu coast and islands.
