| General Information |
| Wetland Type |
estuary, intertidal flats
mangrove (Lingayen Gulf), intertidal flats (Pangasinan wetlands) |
| Location |
Lingayen Gulf
is found on the West Coast of Central Luzon, in Pangasinan and La
Union Provinces. Pangasinan Wetlands are found on the coastal plain
between Dagupan City and Binmaley, Pangasinan, Central Luzon. Agno
River is located in the Northwestern part of the Philippines |
| Altitude |
0-5 masl |
| Area |
about 200,000
ha (Lingayen Gulf) about 3,000 ha (Pangasinan) |
| Coordinates |
19°20'N 121°27'E |
| Biological Diversity |
| Major Endemic Flora |
In Lingayen Gulf, there are
extensive sea grass beds and large areas of algal flats, the main
species being Acanthophora spicifera: Caulerpa spp.,
Gracilaria verrucosa, and Laurencia spp. Mangroves
are present in strips along the coast and HY-Ra fruticans is common
where there is some freshwater influence. |
| Important Flora |
Agno River is
an important staging and wintering area for about 20 species of
migratory bird.
The wetlands support an important fishery
which include mullet Mugil sp., common carp Cyprinus carpio,
Soraderondon sp., milkfish Chanos chanos, and mudfish
Ophiocepahalus striatus.
In Lingayen Gulf, fishes include true
reef-dwellers such as groupers, snappers, siganids, surgeon fish and
butterfly fish, and transient types such as fusiliers, threadfin
bream, flathead and rainbow runners. Offshore fish include slipmouths,
anchovies, yellowfin and skipjack tuna. There is little information on
shorebirds. |
| Threats |
|
Intrinsic source of change |
Destruction of
mangroves for the construction of fishponds is common in Agno River
and Lingayen Gulf. Drastic
over-exploitation of Lingayen Gulf is evident. There are too many
people for the available resources. The stocks of fish, invertebrates
and seaweed are decreasing. Blast fishing and fish poisoning is
rampant. |
| External source of change |
Pollution threat (mercury and
cadmium) from upland-based mining operation is great in the Gulf. |
|
Intervention |
| Development Project /
Interventions |
The DENR has launched a MAngrove
Revegetation Program
The Gulf was the pilot site of the ongoing
Philippine component of the ASEAN-USAID Coastal Resources Management
Program (CRMP) Continuing research on Socio-Economics and resource
evaluation is being undertaken by the University of the Philippines
(Institute of Social Work and Community Development, Marine Sciences
Institute) and UP Visayas (College of Fisheries and Aquatic
Resources)
