Site description Mt Mantalingajan is in southern Palawan, and at 2,086 m is the highest mountain on the island. The Mantalingajan range includes an estimated 70,000 ha of montane mossy rainforest, with stunted forest on the exposed tops. There is lowland rainforest to the north-west of the mountains on the coastal plain, such as around the Ilog-Ilog river. To the south-east of the mountains, the forest has been cleared up to 800 m on the slopes, although some slope forest remains on the top of the flanking coastal ridge from about 400 m upwards. The transition from lowland to montane forest occurs at approximately 1,000 m. The forest becomes progressively stunted with the Mantalingajan peak appearing particularly so, and there are large areas of slope scoured by land-slides, with conifer regrowth occurring.
