Assessment Information [top]

Red List Category & Criteria: Endangered A1bcd ver 2.3
Year Published: 2000
Date Assessed: 2000-06-30
Annotations:
Needs updating
Assessor(s): Asian Turtle Trade Working Group
Reviewer(s): Buhlmann, K., Rhodin, A. & van Dijk, P.P. (Tortoise & Freshwater Turtle Red List Authority)
Justification:
Detailed monitoring of trade and status is urgently required for this species; known trade volumes have declined by about 50% in Indonesia recently despite high demand in the food trade (C. Shepherd, pers. comm.) and the species is considered Critically Endangered in Indonesia (D. Iskandar, pers. comm.). In Thailand, the species is Vulnerable (OEPP 1997) to Endangered and restricted to small, isolated subpopulations. Subpopulations in Brunei, Myanmar, Singapore, and Philippines are considered to be small and of low density, while only those of Singapore and Brunei may be moderately secure. Information for Malaysia is scarce, but a status of Vulnerable was suggested for Borneo and Peninsular Malaysia (I. Das, pers. comm.). Given the numbers in trade, the lack of confirmed extensive subpopulations occurring inside adequately protected areas, the known low reproductive output, and the wide-ranging status assessments summarized here, the species is listed as Endangered.
Previously published Red List assessments:
1996 Vulnerable (VU)
1994 Insufficiently Known (K)
1990 Insufficiently Known (K)
1988 Insufficiently Known (K)

Threats [top]

Major Threat(s): Detailed monitoring of trade and status is urgently required; known trade volumes of the species have declined by about 50% in Indonesia recently despite high demand in the food trade. It is restricted to small and isolated populations over much of its range, although there is a lack of data for some areas.
