This species has been uplisted to Near Threatened on the basis that it is suspected to be in moderately rapid decline owing to on-going forest loss and degradation.

The wholesale clearance of forest habitats in this species's range is taking place as a result of logging, conversion to agriculture and mining activities. Major road building plans pose a further threat. Illegal logging is frequent in some protected areas. Most remaining lowland forest is now leased to logging concessions or mining applications, and there are current explorations in high elevation areas. Mining for chromite and nickel represents a significant threat to many remaining forest areas (J. Ibanez in litt. 2007). On Dinagat, forest is being rapidly cleared for surface-mining (D. Allen in litt. 2011). Logging operations on Basilan in the 1960s, followed by clearance for agriculture and increased hunting, have undoubtedly impacted the species. Forest in some areas, especially in the lowlands, is being cleared under concession and re-planted with exotic trees for paper production. Soil erosion is also a problem in some areas. Anecdotal evidence that the species is affected by deforestation comes from the vast concession held by Paper Industries Corporation of the Philippines (PICOP), where it has declined tremendously over the last 10 years and is now difficult to find (R. Hutchinson in litt. 2012).
Conservation Actions Underway
The species occurs in a number of protected areas.
Conservation Actions Proposed
Carry out regular surveys to monitor the species's population trend. Monitor rates of habitat loss and degradation throughout its range. Increase the area of suitable habitat in protected areas. Improve the effectiveness of existing protected areas.
