Population justification: It is thought to have a smaller population than most species from similar habitat (Whitney et al. 2013), but the total population size has not been quantified. The subpopulation structure is not known.
Trend justification: Over the last ten years to 2020, approximately 3% of tree cover with at least 50% canopy cover was lost from within the species's known range (Global Forest Watch 2021). Projecting forwards, up to 5% may be lost over the next decade. The population size is therefore suspected to be decreasing, at a rate of less than 10% per decade.
