This species has been downlisted from Vulnerable as analysis of recent data suggests that its population is not undergoing rapid on-going declines and is either stable or increasing. However, modelling of the likely effects of mortality caused by longline fishing fleets, combined with potential losses to breeding colonies from sea-level rise and storm surges, suggests it is appropriate to precautionarily predict a moderately rapid population decline over the next three generations (56 years), hence its classification as Near Threatened rather than Least Concern.

In 2003, estimated rates of incidental mortality in longline fisheries in the North Pacific Ocean (based on a moderate bycatch scenario of 8,000 birds being killed per year) resulted in a projected future decline of more than 60% over the next three generations (56 years), if bycatch mortality was not reduced through mitigation measures (Lewison and Crowder 2003). However, the demographic parameters for Lewison and Crowder’s (2003) model, namely survival probability, growth probability and fecundity, were based on data from the 1960s and 1970s, for which it was incorrectly assumed that no bycatch took place (Arata et al. 2009). This implies that the basic parameters for a stable population with no additional mortality were actually estimated from a population already experiencing significant bycatch, and were thus underestimated. This appears to have led to an overestimation of the declines that would result from the annual bycatch scenarios tested by Lewison and Crowder (2003), by counting this source of mortality both within the demographic parameter estimates and within the simulation scenario, effectively doubling the impact of fisheries (Arata et al. 2009). Nevertheless, likely bycatch levels are still predicted to cause a decline in the population, albeit not as rapid as previously projected (Arata et al. 2009). Other studies on this species have confirmed the impact of fisheries bycatch on survival (Verán et al. 2007) and the annual population growth rate (Niel and Lebreton 2005). Annual bycatch was estimated at 5,228 birds in 2005, which, if doubled to account for underestimation, approaches the maximum Potential Biological Removal (PBR) level of 11,980 birds, which is calculated to be the maximum level of off-take possible without causing a decline (Arata et al. 2009). The maximum PBR level for this species has also been estimated at 8,850 birds per year (Niel and Lebreton 2005) and 10,000 birds per year (Cousins and Cooper 2000).
It still remains necessary to robustly model the future impact of bycatch on this species. In the meantime, given the risk of bycatch approaching PBR, and potential risk to nesting habitat from sea-level rise (Storlazzi et al. 2013), it seems appropriate to precautionarily project future declines approaching 30% over the next 56 years (three generations).
