5.3.6 Tianjin Municipality

Site information

Location: Tianjin Municipality, China. 39º 00' N, 117º 42' E

Area: c. 12 000 ha of intertidal flats; c. 20 000 ha of saltpans, shrimp and fish ponds.

Wetland type: Intertidal flats, saltpans, fish and shrimp ponds.

Protected Area status: None.

Threats: Ongoing reclamation for industrial development, oil extraction, roads, saltpans and aquaculture; significant human disturbance from oil extraction and fishing activities (Barter et al. 2001).

Count information

Complete count of Tianjin Municipality coastline only carried out once in mid-May 2000, with good coverage of intertidal flats but limited coverage of saltpans, fish and shrimp ponds (Barter et al. 2001). Department of Biology, Beijing Normal University, conducted surveys of near-coastal wetlands from 1998-2000 (S.P. Zhang in litt..)

Significance of site

Highest count: NM 73 553.

Supports:

  • 17 species in internationally important numbers (NM 14; SM 8; NB 1; B 1);
  • >5% of the estimated flyway populations of Red Knot and Grey Plover during NM;
  • internationally important breeding population of 1 000 Oriental Pratincoles (S.P. Zhang in litt.);
  • the highest recorded internationally important numbers of Common Redshank, Red Knot, Curlew Sandpiper, Black-winged Stilt, Northern Lapwing and Little Ringed Plover in the Yellow Sea during NM, of Common Redshank during SM and of Eurasian Curlew during the NB season.

This site probably supports >100 000 shorebirds during NM. Additional counts would probably allow additional internationally significant species to be identified and also enable improved estimates to be made of shorebird numbers during the migration and non-breeding periods.

5.3.7 Shi Jiu Tuo (Happy Island)

Site information

Location: Hebei Province, China. 39º 08' N, 118º 49' E

Area: c. 2 500 ha

Wetland type: Intertidal flats, fish and shrimp ponds.

Protected Area status: None.

Threats: Human disturbance, possible hotel development and oil exploration (J. Hornskov in litt.).

Count information

Information obtained from birdwatchers who have visited the Beidaihe-Shi Jiu Tuo region to observe bird migration.

Significance of site

Supports:

  • 15 species in internationally important numbers (NM 10; SM 9);
  • >40% of the estimated flyway population of Eurasian Curlew during SM and almost 10% during NM;
  • >5% of the estimated flyway populations of Kentish Plover, Black-winged Stilt and Grey-headed Lapwing during SM;
  • the endangered Spotted Greenshank during NM and SM (maximum counts: NM: 3; SM: 8);
  • the vulnerable Spoon-billed Sandpiper during NM (maximum count: 2);
  • the highest recorded internationally important numbers of Asian Dowitcher in the Yellow Sea during NM and of Eurasian Curlew, Black-winged Stilt, Grey-headed Lapwing and Northern Lapwing during SM.

5.3.8 Linghekou

Site information

Location: Liaoning Province, China. 40º 45' N, 121º 00' E

Area: Proposed Reserve: 140 000 ha; Intertidal flats: 20 000 ha.

Wetland type: Intertidal flats, shrimp and fish ponds, and saltpans.

Protected Area status: None.

Threats: Reclamation for shrimp ponds and oil extraction, human disturbance, unsustainable fishing and oil industry pollution (Barter et al. 2000b).

Count information

Complete count of coastline carried out once, during NM, with good coverage of intertidal flats but only limited coverage of saltpans, fish and shrimp ponds (Barter et al. 2000b).

Great Knot 17 540 1
Grey Plover 2 739 1

Significance of site

Highest count: NM 34 445.

Supports:

  • 2 species in internationally important numbers during NM;

This site probably supports >50 000 shorebirds on NM. Additional counts during NM, and counts during SM, would almost certainly allow additional internationally significant species to be identified and also enable improved estimates to be made of shorebird numbers during the migration periods.
