Population justification:

The total population is estimated at 41,086 pairs per year, equating to c. 82,000 mature individuals, and perhaps more than 160,000 individuals of all age classes, using the ratios presented by Gales (1998).

Trend justification: Decline over three generations (71 years) was estimated at 51%, assuming a continuing decline at Amsterdam Island since 1982, and that populations elsewhere remained stable. Amsterdam Island data indicated a 30% decline from 1982-2006 (though split into 58% decline 1982-1995 and stable 1996-2005), with all other populations assumed to remain stable. The Amsterdam Island calculations of decline were based on a study plot (over 250 pairs in 1978 to 113 pairs in 2005). The small study plot declined at 3.7% per annum 1978-2005, while the whole Amsterdam Island population declined by 1.3% per annum 1982-2006. The trend analysis was conducted on the basis of the overall 1.3% decline per year over a 24 year period for Amsterdam Island.
