Featured Key Biodiversity Area

Pagbilao Bay, Quezon

Important Bird & Biodiversity Areas (IBAs) are sites of international significance for the conservation of the world’s birds and other wildlife. The site is also a Key Biodiversity Areas (KBAs)– sites that contribute significantly to the global persistence of biodiversity. Having met the A1 Global IBA Criteria, the Pagbilao and Tayabas Bay IBA area is known or thought regularly to hold significant numbers of a globally threatened species making it as an important staging and wintering area for migratory herons, egrets and shorebirds.

Bird Biodiversity: Nine species of Ardeidae have been recorded, and up to 500 shorebirds of 16 species have been counted at the Pagbilao Bay (and nearby Quezon National Park. The threatened Chinese Egret and Philippine Duck may both occur in significant numbers, and the records of the threatened Philippine Kingfisher in the mangrove forests there are also of interest.

Non-bird biodiversity: The Bay provides natural breeding and nursery grounds for a wide variety of molluscs, crustaceans, fish and other aquatic organisms of economic importance.


The area includes a 700 ha patch of mangroves in the delta of the Palsabangon River and its tributaries in Pagbilao Bay, which is protected from strong wave action by the islands of Pagbilao Grande, Dampalita and Patayan. Although much of the mangrove has been converted to fish culture ponds, 100 ha of a mangrove forest is protected by DENR at the Mangrove Forest Research Centre at Talipan, and there are smaller pockets at Padre Burgos, Unisan, Pitogo and Macalelon.
