This species has a very small range, in which habitat is being lost and degraded, although its population is not considered to be severely fragmented or restricted to a few locations. Its population is thought to be moderately small and is likely to be in decline owing to habitat loss. It is therefore considered Near Threatened, although further studies are urgently needed to validate this assessment.
