This species has a small population which is suspected to be declining as a result of clearance and degradation of forests for plantation agriculture and infrastructure projects. More rigorous application of the critieria means this species has been downlisted to Near Threatened as the population declines are suspected based on habitat loss and degradation, and are not currently supported by quantitative data.
