Population justification: The population in Cambodia was estimated at 294 displaying males or c.600 individuals in 2007 (Gray et al. 2009), with just 32-60 individuals left in Nepal. No recent estimates are known from India but the total global population for this species is likely to fall in the range 250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals. |
|
Trend justification: A very rapid decline in the global population is estimated to have occurred over the last three generations, based on figures from Cambodia. Current and projected rates of decline in the Cambodian population alone equate to a decline in the global population exceeding 80% in three generations (T. Gray in litt. 2006). |
