Site description This IBA includes the island of Tawi-tawi (48,400 ha), the second largest in the Sulu archipelago, and many small associated islands including Tandungan, Tandubatu, Dundangan and Baliungan in the Tandubas group. Tawi-tawi is largely undeveloped, with some primary forest and large areas of secondary forest inland, as well as forested islets and rich reefs offshore, although much of the forest around the coastal fringe has been converted to coconut plantations. The largest remaining areas of forest on Tawi-tawi are on the central ridge, which rises to just over 500m, and in the eastern half of the island. Forest has been estimated to cover 250-350 km2 of the island in total, but recent observations (including from the air) suggest that most of it has been selectively logged and that little primary forest remains. There are also small remnants of closed-canopy forest close to Batu-Batu village, mostly on rocky outcrops or inaccessible areas, some logged forest extending across the island from Batu-Batu around Tarawaken, and in the Balimbing, Buan and Tataan areas. The eastern islands of Tandungan, Tandubatu, Dundangan and Baliungan are rather hilly and were until recently well forested, but the fringing mangroves have now mostly been cleared for firewood and large areas of forest inland have been logged. However, some areas of unlogged forest remain, at least on the higher parts of Baliungan. Some of the other small islands south of Tawi-tawi have areas of secondary forest or scrub, but many of them are extensively cultivated and none of them appear to have significant areas of primary forest. The main land-uses in this IBA are subsistence agriculture and the extraction of forest products. Tawi-tawi and its associated islands are of great scenic beauty, and have considerable potential for tourism, but this is not possible at present because of political instability.
