The Sulu Archipelago rain forests ecoregion covers the Sulu Archipelago, excepting Basilan Island at the northern end, in the southwest of the Philippines. The islands are separated enough from Borneo to the south and Mindanao to the north that they have developed their own distinctive floral and faunal communities. Most of the original rainforest has been removed or disturbed for agriculture, and political instability in the islands has hampered conservation efforts.
