Justification of Red List category

This species is classified as Critically Endangered because until very recently its population was extremely small and declining owing to land-use change (particularly a decrease in grazing pressure) and predation by invasive predators. The population has recently shown some signs of recovery however, and if it continues to remain above 250 mature individuals and/or continues to increase or stay stable for a five year period it is likely to be eligible for downlisting. Given uncertainty over the impacts of the impending construction of an airport (which may well be significant), and given that these impacts will become clearer in the near future, the status of this species should continue to be monitored closely.
