Wetlands of international importance in Negros Occidental
BY: ERROL ABADA GATUMBATO
The recent Asian Waterbird Census in Negros Occidental jointly conducted by the Philippines Biodiversity Conservation Foundation, Inc., Negros Forest and Ecological Foundation, Inc., Department of Environment and Natural Resources and Provincial Environment and Management Office affirmed the province’s importance in terms of biodiversity conservation in global scale. The findings of the survey may also boost the potential of Negros Occidental as an important birding site in the Philippines.
Lisa Paguntalan, PBCFI Director for Field Operations and one of the members of the survey team disclosed that migratory bird species are abundant in wetlands and coastline areas of Pulupandan, San Enrique, Pontevedra and Ilog municipalities and Kabankalan City. The variety and number of species found in these areas are good enough to propose their declaration as Wetlands of International Importance under the Ramsar Convention.
In Pulupandan, the survey team recorded a total of 38 waterbird species comprising of 2,851 individuals. This site accounts the highest number and population of duck species among the areas covered by the survey. Among the species recorded in this site were Black-winged stilts, Egrets and Whistling duck. The endemic Philippine duck has been noted also in Pulupandan wetlands. In San Enrique-Pontevedra wetlands, some 37 waterbird species involving 10,939 individuals were counted by the survey team. Thirty two species in these sites are migratory birds. Species identified in San Enrique-Pontevedra wetlands included Asiatic dowitcher, Chinese egret, Eurasian curlew, Far eastern curlew and Black-tailed godwits.
On the other hand, the survey in Kabankalan-Ilog wetlands recorded a total of 50 waterbird species of which 34 are migratory birds. The individual species count in these wetlands reached about 13,764. Some species identified in these sites are similar with the species discovered by the survey team in San Enrique-Pontevedra wetlands.
Paguntalan, an ornithologist by profession, said the recent waterbird census in Negros Occidental yielded some interesting scientific notes and facts. She claimed the survey recorded the Little stint (Calidris minuta), which was only recorded in the country in 1903 and it was the first record of the species in Negros since 1888. The survey also resulted to the 4th record of Caspian tern in the Philippines and so far the highest number of individuals recorded. The 4th record in the Philippines and second record in Negros of Sanderling (Calidris alba) were similarly obtained during the waterbird census. The 3rd country record of the Broad-billed sandpiper (Limicola falcinellus) was further made during the survey.
The surveyed areas are actually considered migration or navigational routes of the migratory birds or also known as Migratory Flyways. In the Philippines, only the Olango Island in Cebu has been recognized as part of the East Asian – Australian Flyway. These migratory sites are very important to several species of birds that are taking refuge in tropical countries during winter. Usually migratory birds attract the interest of global birding community.
So far, there are only four sites in the Philippines declared as Wetlands of International Importance and these are the Olango Island in Cebu, Naujan Lake in Oriental Mindoro, Tubbataha Reef in Palawan and Agusan Marsh in Agusan del Sur. The Convention on Wetlands of International Importance or popularly known as Ramsar Convention is an inter-governmental treaty providing the framework for national action and international cooperation for the conservation of wetlands and their resources. It is the only global environmental treaty focusing on a particular ecosystem and was adopted in 1971. The Philippines is one of signatories of the treaty.
