Justification
Listed as Vulnerable as it is restricted to lower altitudes, where deforestation is heavy and there is no evidence the species will survive in degraded areas. During the last 10 years over 30% of evergreen lowland forest has been cleared in species range and it is predicted that the 40% of the remaining area will be converted into plantations in the next decade.
