Listed as Near Threatened since although this species is still relatively widely distributed, it depends on areas of reasonably undisturbed forest habitat, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.
