It is an abundant species.
Habitat loss due to infrastructure development for human settlement, clear cutting of forests and fire are localized threats, but there is no major threat to the species overall.
The range of the species includes several protected areas. More research into the species' Extent of Occurrence is needed.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species might be a complex of more than one species.
