Site description The island of Dinagat lies off the northeastern peninsula of Mindanao, and has a total area of 66,300 ha. Much of the island has been cleared, but several areas of closed canopy forest remain there (which in places probably extend down to sea-level), principally on the Mt Kambinlio and Mt Redondo ranges in the east of the island. The highest point on the island is below 1,000 m, and the forest is mainly lowland in type. The major economic activities on the island are agriculture, fisheries and the collection of forest products.

Other biodiversity Dinagat Island has three endemic species of mammals, which is a very high number for such a small island. These are the endangered Dinagat Gymnure Podogymnura aureospinula, which is common in both primary and secondary forest there, the Dinagat Hairy-tailed Rat Batomys russatus and the Dinagat Cloud Rat Crateromys australis, which is known only from the type specimen. The endangered White-winged Flying Fox Pteropus leucopterus is also found on the island.

Protection status Not officially protected.
