Scientific Name: Ansonia endauensis Grismer, 2006
Taxonomic Source(s): Frost, D.R. 2016. Amphibian Species of the World: an Online Reference. Version 6.0 (31 March 2016). New York, USA. Available at: http://research.amnh.org/herpetology/amphibia/index.html.

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Lee Grismer
Reviewer(s): Simon Stuart, Neil Cox
Justification:
Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.

Geographic Range [top]

Range Description:This species is so far known only from Sungai Semawak, in Endau-Rompin National Park, Johor Province, Peninsular Malaysia at 46m asl (Grismer, 2006). The type locality is 5km west of the Endau-Rompin National Park visitor centre at Peta (Grismer, 2006). This species presumably occurs more widely, beyond the confines of Endau-Rompin National Park.

Population [top]

Population:There is no information on its abundance. It is so far known from only four specimens (Grismer, 2006).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:All individuals were collected from the same small, rocky stream (Sungai Semawak) which runs through a closed-canopy portion of lowland forest (Grismer, 2006). They were found at night following periods of afternoon precipitation, and were perched no higher than one metre above the ground on small leaves overhanging the streambed (Grismer, 2006). Its breeding has not been observed (Grismer, 2006), but it is presumably by larval development in streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Its only known location is in a well-protected location. However, it is occurs more widely, it could be found to be present in places where its habitat is at risk from logging and agricultural expansion (especially oil palm plantations).

Conservation Actions [top]

Conservation Actions: It occurs in the Endau-Rompin National Park. Surveys are needed to determine its geographic range, abundance, ecological requirements, threats and conservation needs.
