Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Robert Inger, Djoko Iskandar, Peter Paul van Dijk, Leong Tzi Ming, Indraneil Das
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species occurs in Peninsula Malaysia, Singapore, Indonesia (Sumatra, Natuna Besar and Pulau Bintan), and Borneo. It probably occurs more widely than current records suggest, especially in areas between known sites.
Countries occurrence:
Indonesia; Malaysia; Singapore

Population [top]

Population:There are no estimates of the size of subpopulations in Borneo, but it appears to be common but not abundant in intact swamp forests. It is uncommon in Sumatra and Singapore (Lim and Lim, 1992), and presumably localized or uncommon in Peninsular Malaysia.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Swamp forests are the primary habitat for this toad. It is known to breed in standing water. It has been recorded from rubber plantations, presumably close to primary forest (Dring, 1979, Chan-ard et al., 1999).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The species' habitat is being rapidly reduced due to the expansion of oil palm plantations, infrastructure development and logging.

Conservation Actions [top]

Conservation Actions: Preservation of some areas of swamp forest is needed to save the Bornean subpopulations. In mainland Southeast Asia population status information is needed. It is recorded from the Sungai Dusun Game Reserve in Peninsular Malaysia.
