Kalibo Wetlands
Location:
11°32'-11°46'N; 122°16'-122°30'E; near the towns of Kalibo, New Washington and Aibasan, on the north coast of Panay Island, Aklan Province.
Area:
c.25,000 ha.
Altitude:
Sea level.
Biogeographical Province:
4.26.12.
Wetland type:
01, 02, 04, 05, 06, 07 & 19.
Description of site:
The estuarine and delta system of the Alcan River near Kalibo, and the extensive tidal lagoon and creek system of Batan Bay and Banga Baylet to the southeast. Mangrove swamps constitute about 80% of the area; there are extensive intertidal mudflats at the mouth of the Alcan River and in Batan Bay, stretches of rocky shore and sandy beach, and rice paddies inland. Salinities range from 16-31 p.p.t.
Climatic conditions:
Humid tropical climate with two pronounced seasons, a relatively dry season from January to April and a wet season for the rest of the year with the heaviest precipitation occurring from October to December (Type I/III). The average annual rainfall is about 3,800 mm, and the mean annual temperature 27°C.
Principal vegetation:
Mangrove swamps and rice paddies.
Land tenure:
No information.
Conservation measures taken:
None.
Conservation measures proposed:
 
Land use:
Shrimp fishing is very important in the area, particularly in Batan Bay.
Possible changes in land use:
Proposed irrigation schemes to service an additional 10,260 ha of agricultural land in the water catchment area of the Alcan River are likely to have an impact downstream in the estuary and delta.
Disturbances and threats:  
Economic and social values: The rich shrimp fishery provides a livelihood for many of the local inhabitants. Sixteen species of decapod crustaceans are harvested commercially.
Fauna: The very rich invertebrate fauna includes at least 39 species of decapod crustaceans belonging to 13 families.
Special floral values: No information.
