Known from a single locality where the forest extent is estimated to be only 19 km² (extent of occurrence). The area is protected but the habitat is threatened by human activities, such as fire and harvesting, outside the reserve and this is treated as a continuing decline in extent and quality of habitat. The species meets the requirements for listing as Critically Endangered.
Previously published Red List assessments:
1998 Critically Endangered (CR)

Threats [top]

Major Threat(s): Although the area is protected the habitat outside is being heavily impacted by human activities such as increased frequency of fires to clear land for shifting agriculture, logging and other harvesting. Given the small size of the forest reserve, this area is probably also being impacted.
