Justification of Red List category
This species qualifies as Critically Endangered because it has an extremely small range, wholly confined to one upland area where habitat quality is continuing to decline. It has apparently always been rare, although the reasons for this are unclear and the range and population trends are difficult to judge, because it is extremely elusive, and occurs in some areas that are difficult to access. Reintroduction of captive-bred individuals failed to lead to a significant population increase (Switzer et al. 2013); until declines in habitat quality are halted and predation by introduced mammals is addressed, the species will not recover. However, the population, whilst small, appears to be stable (Crampton et al. 2017).
