Animalia Chordata Amphibia Anura Bufonidae

Scientific Name: Ansonia platysoma Inger, 1960

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
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)
Justification:
Listed as Endangered, in view of its extent of occurrence of less than 5,000 km2 and area of occupancy of less than 500 km2, with all individuals in fewer than five locations, and a continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description:This Bornean endemic occurs at a number of sites within Kinabalu National Park and at other sites in the Crocker Range south of Kinabalu in Sabah (Malaysia); it is also known from Gunung Mulu National Park in Sarawak. The altitudinal range in Kinabalu is 600-950m asl (Malkmus et al. 2002), and its overall altitudinal range is 750-1,600m asl.

Population [top]

Population:This species is abundant at most locations where it has been reported (such as the Crocker Range).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Adults are found on the floor of montane forests and move to clear, rocky mountain creeks to breed. The larvae cling to rocks in torrents in these streams and presumably feed on lithophytes. It appears not to be able to survive in modified habitats.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Logging in the submontane and montane forests could potentially lead to siltation of the streams needed for larval development and result in loss of the lithophytes.

Conservation Actions [top]

Conservation Actions: The species is known to be present in the Kinabalu and Gunung Mulu National parks, both of which are reasonably well managed; however, further protection of the remaining forest habitats, and continued management of the existing protected areas, are needed. Additional surveys of potentially suitable sites in Kalimantan are required to establish whether this species occurs there.
