Population justification: The population size has been estimated at >10,000 mature individuals (Rosenberg et al. 2016), which equates to >15,000 individuals in total.
Trend justification: Between 1970 and 2014, the species is suspected to have declined by 95% (Rosenberg et al. 2016). This equates to an annual decline of 6.6%, or a decline of 51.1% over 3 generations (10.5 years).
