Although this species appears to persist in highly degraded habitats, its ecological requirements are poorly known, and habitat loss and degradation on Numfor are on-going. Given that it occurs within a very small range, and is likely to have a small to moderately small, but not severely fragmented population, it is considered to be Near Threatened.
