Spatial analysis of Important Bird Area boundaries in the Philippines: gaps and recommendations

May 18, 2005

Jose Don T. De Alban. 2005. 

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 data 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 Philippine IBAs are completely known ornithologically, and that the original IBA delineation relied on historical records of trigger bird species?
