As of 2010, it is evaluated as a near-threatened species by the IUCN. It meets the criteria for this classification because it is experiencing habitat destruction. Its extent of occurrence is likely less than 20,000 km2 (7,700 sq mi), and is close to qualifying for the more serious designation of "vulnerable". It likely has a small population size which is also declining. Specific threats this species faces include mining, quarrying, deforestation, and hunting.
