Site description The town of Bislig on the eastern coast of Mindanao is the main point of access into the vast Paper Industries Corporation of the Philippines (PICOP) concession area. This logging concession covers c.182,682 ha and extends from the lowland forests inland from Bislig (which are included in this IBA) to the higher altitude forests on Mt Pasian and Mt Agtuuganon (which are included in IBA PH087). The concession includes large areas of logged lowland forest and some areas of primary lowland forest, and over 40,000 ha devoted to plantation forestry. PICOP operates a fully integrated wood industrial complex at Bislig, the first and only one of its kind in Asia. It includes the first newsprint plant in Asia. It is a popular destination for birdwatchers, as it is one of the best places to see several scarce lowland forest birds.
