Site description Basilan Island lies c.20 km south of the tip of the Zamboanga Peninsula of south-western Mindanao. It is a hilly island, with several peaks that ascend to almost 1,000 m, including Mt Kebang (Twin Peak) and Mt Mohadji. This IBA includes the forests that remain in the hilly central part of the island, which are recommended by the DENR-9 for protection under the NIPAS as the Basilan Natural Biotic Area. An area of 234 ha of primary forest is reported to remain on Mt Mohadji, which also has patches of secondary forest which cover a total area of 2,500 ha. These areas were logged more than 20 years ago, but have now regenerated. Most of this is lowland forest, with limited areas of mossy forest around the highest peaks.
