Population justification: A survey in 2011 using line transect and banding counts estimated the population at 740 individuals, equating to 490 mature individuals, this figure is considerably lower than previous estimates as a result of the tsunami in 2010 (Hahn et al. 2015) and the population is likely to have recovered slightly by now (I. Hahn in litt. 2015). The population was previously estimated to number 2,500-3,000 individuals in total, roughly equating to 1,700-2,000 mature individuals (P. Hodum in litt. 2007). The current population is therefore estimated at a minimum of 490 mature individuals or 740 individuals.

Trend justification: The species is suspected to be decreasing at a rate of 1-9% over ten years, owing to the combined threats of habitat loss and degradation, predation and competition within its tiny range.
