Population justification: The remaining population is assumed to be tiny (fewer than 50 individuals and mature individuals) based on paucity of recent records (although these include eight since 1983).
Trend justification: Population trend is unknown but it may well be declining owing to effects of rats, cats and feral pigs on Gau Island.
