Site description Marinduque is an island of 172,700 ha off the southwestern coast of Luzon. It is hilly and reaches a maximum altitude of 1,153 m. Two small blocks of old growth forest are shown on recent forest cover maps around the highest peaks in the center and south of the island.

This IBA includes the small Torrijos Watershed Reserve, which has an area of 105 ha.
