Important Bird Areas (IBA) in the Philippines were identified using a set of international criteria to determine globally important priority areas for biodiversity conservation. The IBA boundaries were delineated using dat on trigger bird species distribution coupled with available land cover data.
Important Bird Areas (IBA) in the Philippines were identified using a set of international criteria to determine globally important priority areas for biodiversity conservation. The IBA boundaries were delineated using dat on trigger bird species distribution coupled with available land cover data.
Present conservation work has been guided using the IBAs as a directory of key conservation sites. But how relevant and accurate are the IBA boundaries, considering that less than 50% of Phlippine IBAs are completely known ornithologically, and that the original IBA delineation relied on historical records of trigger bird species? The mapping of IBAs illustrated that the original IBA delineation was not well related to forest extents and that 46% of the country’s forest habitats lay beyond IBA boundaries.
Forests remained extensive within large Endemic Bird Areas (EBA), but smaller EBAs like Mindoro and Negros Panay had 8% and 5% forests left, respectively. Mining areas were heavily in conflict with IBAs wherein 21% of forests in IBAs were similarly under mining applications. The implications of the gaps in existing IBA boundaries were discussed in light of aggressive promotion of mining and how conservation work and policy agenda in the country could be affected. Challenges and threats in conserving the IBAs at the local and national levels were identified by examining overlaps with mining claims and conflicting tenurial instruments.
