Justification of Red List category
The population trend of this albatross remains poorly known, due to high inter-annual variability in breeding numbers and estimates prior to 2007 are not comparable with those made since. Analysis of recent data suggest that the trend may in fact be stable, but the species remains categorised as Near Threatened given the continuing uncertainty over its trend and because, given its longevity and slow productivity, and a high rate of mortality recorded in longline and trawl fisheries, it may be declining at a moderately rapid rate.
