Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Robert Inger, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul Yambun
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 streams in 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 very rapidly due to widespread forest loss within its range, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description:This Bornean endemic is widely distributed in relatively steep terrain in Malaysia and Indonesia, from 150-750m asl.

Population [top]

Population:It appears to be abundant at scattered lowland localities.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Adults disperse widely over the floor and herb stratum of rainforest. It requires small, clear, rocky-bottomed streams to breed in, and larvae live in torrents, clinging to rocks and feeding on lithophytes. It appears to be unable to adapt to modified habitats.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat to the species is deforestation of large portions of the habitat, with the resultant loss of adult and juvenile (through the siltation of streams) feeding microhabitats. Conversion of forest to oil palm plantations is also a threat and it is possible that a broad portion of its range might soon be converted to Acacia plantations.

Conservation Actions [top]

Conservation Actions: The species is known from several protected areas, including Kinabalu National Park, which is in Sabah, where good, large areas of forest are now protected, as are some sites in Sarawak. The species might well occur in Kalimantan but existing forest preserves and parks are not well protected. Further protection of large areas of rainforest is needed.
