Population justification: The population size is unknown, in part due to its exact geographic limits remaining unknown. It is usually described as locally common (Lambaihang et al. 2003) or uncommon (Eaton et al. 2021). Given the total area of forest it is currently suspected to occupy (c.2,000 km²), it is possible that the population may number fewer than 10,000 mature individuals if the species proves to occur at very low density; however, it is considered more likely to exceed this, especially given it probably occurs in additional areas of forest further west. The subpopulation structure is wholly unknown: although it is monotypic, the population is disjunct and multiple subpopulations are suspected.

Trend justification: The principal threat, forest loss, is currently occurring at a negligible rate equivalent to <0.5% over the last 10 years (Global Forest Watch [2021], using data from Hansen et al. [2013] and methods disclosed herein) and only along the peripheries of the species' elevational limit. This rate is considered too low to cause a decline in mature individuals. In the absence of other threats, the population is therefore suspected to be stable.
