Population justification: The species appears to have declined dramatically and is now known from comparatively few sites, occurring at low densities everywhere. The population may now number as low as 1,000 individuals (J. C. Eames in litt. 2007), and so is placed in the band 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Trend justification: Very rapid declines are suspected over the past three generations in this long-lived species. Habitat conversion has been a major threat over the period with riverine systems amongst the most disturbed and most degraded environments in South-East Asia.
