Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat on Bohol, Samar, Leyte, Biliran, Maripipi, Dinagat and Mindanao in the Philippines.

Geographic Range [top]

Range Description: This species occurs in the rainforests of Bohol, Leyte, Biliran, Maripipi, Dinagat, Panglao, and Mindanao Islands in the Philippines, from sea level to 700m asl. It probably occurs a little more widely than current records suggest, especially in areas between known sites.

Population [top]

Population: It is common to very common in humid forest.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits arboreal microhabitats in lower montane and lowland forests; it also survives in disturbed habitats adjacent to forested areas. It breeds by direct development and is believed to deposit its eggs in leaf axils, epiphytes, and aerial ferns.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is the loss of habitat due to shifting agriculture and the logging of lowland rainforest.

Conservation Actions [top]

Conservation Actions: The range of this species includes a few protected areas, including Mount Malindang National Park and Mount Apo Natural Park. The designation of the remaining rainforests on the islands of Mindanao, Leyte, Bohol, and Dinagat as protected areas is needed.
