This BioProvince (as defined by Armen Takhtajan) comprises the Philippine Achipelago (except Palawan Island) and the Calamian Islands, Basilan Island, the northernmost island in the Sulu Achipelago, the Babuyan Islands and the Batan Islands. The geology is complex and varied but it is largely mountainous with eleven mountain peaks ranging from 1700 to above 2900 m of which the highest is Mount Apo (2929 m) in Mindanae. Like all tropical lands the Philippines have heavy annual rainfall. It occurs over two main periods - one brought by the northeast monsoon occurs from December to March mainly affecting western areas and the other from July to November is mainly as a result of typhoons, and due to their orientation mainly affects Luzon.
