Population justification: The global population size has not been quantified.

Trend justification: The population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes. It may be increasing if, like close relative H. smyrnensis, it is able to successfully utilise farmland and oil palm plantations.
