Population justification: The population is estimated to number 1,000-25,000 individuals, roughly equating to 670-17,000 mature individuals.
Trend justification: Precipitous declines have occurred in parts of South-East Asia, but trends in India, which now probably holds the bulk of the population, are less clear, making analysis of past population trends difficult. Nevertheless, the species is expected to undergo a moderately rapid reduction over the next three generations, as threats, such as dam construction and disturbance, increase in prevalence.
