Justification of Red List category
This species is classified as Vulnerable because it has a very small range and population. Introduced herbivores are degrading forests in its range, but it appears to tolerate some habitat modification and there is (as yet) no evidence of a decline in its range or population. Regular surveys are required so that trend data can be collected, and if it is found to be in decline it may warrant uplisting to Critically Endangered.

Population trend: stable

Extent of occurrence (breeding/resident): 30 km2

Country endemic: yes
