Population justification: The species's total population was estimated at c. 300 individuals in 2008, indicating that there are probably fewer than 250 mature individuals remaining, hence the population is placed in the band 50-249 mature individuals.
Trend justification: Population estimates of c.1,260 individuals in 1969 (Dharmakumarsinhji 1971 in Dutta et al. 2010) and c.300 individuals in 2008 (Dutta et al. 2010) suggest that the species has undergone a decline equivalent to c. 82% over 47 years (estimate of three generations), assuming an exponential trend. The results of population viability analysis (Dutta et al. 2010) lend some support to a predicted decline of over 50% during the next 47 years if no additional conservation actions are taken.
