Justification of Red List category
This species qualifies as Critically Endangered because it has an extremely small population which is inferred to be in decline owing to habitat degradation and the impact of invasive predators. It is found in one site only, where it occupies a very small area of forest which, although it is not severely threatened, remains effectively unprotected and might be vulnerable in the future. Recent observations extend the known range, elevation and habitat, but the population is assumed to remain extremely small.
