Red List Category & Criteria: Near Threatened ver 3.1

Justification:
Listed as Near Threatened since although this species is still relatively widely distributed, it depends on areas of undisturbed forest habitat, and so its Extent of Occurrence is probably not much greater than 20,000 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 species has been recorded from the northern half of Borneo, including Sabah (Malaysia), Sarawak (Malaysia), Kalimantan (Indonesia), and Brunei Darussalam. It probably occurs more widely than current records suggest, especially in areas between known sites. It has been recorded below 250m asl.

Population [top]

Population: This species forms rather large breeding aggregations, suggesting that it is locally abundant.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs in flat or hilly rainforests, and forms breeding aggregations around forest rain pools and swampy ground. Spawning sites are on the forest floor (Malkmus et al. 2002).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat to this species is clear-cutting of lowland forest.

Conservation Actions [top]

Conservation Actions: It is known from a number of protected areas in Borneo, but more effective protection of lowland forests in other parts of Borneo is necessary.
