Justification of Red List category
This species is classified as Near Threatened. Although it has a tiny range and is potentially threatened by chance catastrophes, such as cyclones and the establishment of exotic predators (it almost meets the requirements for listing as Vulnerable under criterion D2), these threats are unlikely to drive the species to become Critically Endangered or Extinct in a short period.
1300-2000 mature individuals
