Population justification: The population size has not been quantified.
Trend justification: The population trend has not been investigated, but the only threat known to the species is the logging and fragmentation of forests within the range. Tree cover within the range is lost at a rate of 5% over three generations (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Under the assumption that population declines are roughly equivalent to the rate of tree cover loss, they are here tentatively placed in the band 1-9% over three generations.
