5.3.18 Seosan Reclaimed Area

Site information

Location: Chunchongnam Province, South Korea; 36º 39' N, 126º 23' E.

Area: 17 500 ha

Wetland type: Mostly lakes and rice fields formed by coastal reclamation which was completed in 1984; also intertidal flats (2 000 ha).

Protected Area status: None.

Threats: None known (Moores 1999b).

Count information

Counts were conducted twice during NM and three times during SM in 1997 and 1998. The count for the site has been obtained by summing the species maxima over the 1997-1998 period (Yi & Kim in prep.).

5.3.19 Geum Gang Hagu

Site information

Location: Chollabuk Province, South Korea; 36º 00' N, 126º 40' E.

Area: 12 000 ha.

Wetland type: Intertidal flats and barraged river.

Protected Area status: None.

Threats: 7 km of southern bank already reclaimed. Proposed to completely reclaim remaining mud flats. Pollution, tourism and changing agricultural methods (Moores 1999b).

Count information

Counts were conducted twice during NM and three times during SM in 1997, 1998 and 1999 (Yi & Kim in prep.). Additional counts were made during NM and SM in 1998 and in the 1998-1999 NB season (Moores 1999a). Roost counts obtained at Yubu Island, which is located within the estuary, have been included in the site data.
