Justification of Red List category
This species is listed as Vulnerable because it has an extremely small range. Introduced herbivores are degrading habitat within its range, but it appears to tolerate some habitat modification and there is (as yet) no evidence of a decline in range or population. If habitat degradation was to intensify, the species could quickly qualify for a higher threat category.

Population trend: stable

Extent of occurrence (breeding/resident): 30 km²
