Population justification: The population is preliminarily estimated to number at least 10,000 individuals, roughly equating to at least 6,700 mature individuals. This value however requires confirmation, and an accurate quantification of the population size is urgently required.

Trend justification: The only threat known to this species is the loss, degradation and fragmentation of its habitat. Over the past three generations (12.3 years), 4% of tree cover has been lost within the range; however since 2016 tree cover loss has been accelerating to a rate equivalent to 6% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore unlikely to exceed 10% over three generations.
