Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Arvin Diesmos, Angel Alcala, Rafe Brown, Leticia Afuang, Genevieve Gee, Robert Inger, Robert Stuebing, Indraneil Das, Paul Yambun, Maklarin Lakim
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Near Threatened since although this species is still relatively widely distributed, it depends on areas of undisturbed forest habitat, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description:This species is known from central and northern Borneo (both Malaysia and Indonesia), and the islands of Balabac and Palawan in the Philippines. In Borneo it has been recorded from 700-2,900m asl, but in the Philippines it is known from much lower altitudes of 30-1,000m asl. It probably occurs more widely than current records suggest.
Countries occurrence:
Indonesia; Malaysia; Philippines

Population [top]

Population:Large sample sizes at one locality in central Palawan indicate that this species might have been common at the time.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in submontane and montane forests, where it is usually seen in the low shrub layer, and has not been found outside forests. It breeds by direct development.

Threats [top]

Major Threat(s): In the Philippines some populations of this species are threatened by habitat conversion to agricultural land. In Borneo, deforestation is a major threat.

Conservation Actions [top]

Conservation Actions: Some of the remaining patches of this species' habitat are currently within protected areas.
