Ansonia latidisca


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Ansonia latidisca
Species Authority: Inger, 1966

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
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 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 species is known only from two locations in the western corner of Borneo: Mount Damus, near Sambas, in Kalimantan (Indonesia), and Mount Penrissen, in western Sarawak (Malaysia). It possibly occurs more widely than current records suggest, especially in areas between the two known sites.
Indonesia; Malaysia

Population [top]

Population: There are no estimates of population size. Only two specimens are known and it was last collected over 50 years ago. There are no recent records, probably due to lack of herpetological work within its range.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The known localities were primary, hilly rainforest at the time the frogs were collected. The adults are primarily terrestrial, and the larvae are found in forest streams. If it is similar to other members of its genus, it is unlikely to be able to adapt to modified habitats.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat to this species is habitat loss and degradation primarily as a result of logging. The remaining suitable habitat within its range has been almost entirely converted for recreational use (one of the two known sites, Mount Penrissen, has recently been converted into a golf course), or converted to cultivated land. An additional threat is the resultant sedimentation of streams (following logging) which results in the deterioration of breeding habitat.

Conservation Actions [top]

Conservation Actions: Effective preservation of hilly rainforest in the regions of the two known localities is essential. In addition, further survey work in the hilly border area of Sarawak and Kalimantan is necessary to help provide a better indication of the species' current population status.
