Site details
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.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs. Alliance for Zero Extinction (2018): site confirmed as an AZE site during the AZE project (2015-2018). Taxonomy, nomenclature and Red List category follow the IUCN 2016 Red List.
Additional biodiversity: Many of the threatened and restricted-range species of the Mindanao and Eastern Visayas Endemic Bird Area have been recorded on Dinagat, most of which are likely to have populations in the forests on Mt Kambinlio and Mt Redondo. The relatively large numbers of the critically endangered Philippine Cockatoo on the island are of particular note, and both Mindanao Bleeding-heart and Celestial Monarch have been found to be relatively numerous there. The restricted-range Rusty-crowned Babbler is represented on the island by the endemic subspecies S. c. capitalis. Non-bird 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.

Threats
Summary of threats to biodiversity at KBA: The timber on Dinagat is of poor quality, but wood-cutting and encroachment into the forests for kaingin and illegal commercial logging are reported to occur there. The upgrading of a road through the centre of the island could increase the rate of encroachment in the future. There have been reports of chromite mining on a hill adjacent to Mt Kambilio.
