Population justification: The population size of this species has not been formally estimated, but at most sites occupied it has been found to be relatively common (Mahood et al. 2012, Gray et al. 2013, Berryman 2023). Given the disjunct nature of its range, its population is assumed to comprise multiple subpopulations, although the connectivity between these is unknown.

Trend justification: In some parts of its range, the population trend of this species is probably stable. At Xe Sap NPA, for example, Gray et al. (2013) found it to be relatively common and the lack of evidence of forest cover loss or degradation (Grantham et al. 2020, Global Forest Watch 2023) and the remote nature of these forests, suggests that any population here has not declined in the past c.20 years. Elsewhere, however, there are anecdotal reports (R. Craik in litt. 2024) it has been declining locally on the Mang Canh Plateau since its discovery by Mahood et al. (2012) and at Dong Ampham, Lao PDR, Berryman (2023) reported significant habitat alterations and, in places, total destruction caused by gold mines within the elevational range of this species. However, it has also been described as tolerant of some degradation, such that forest modification (as is common in both Viet Nam and Lao PDR) may not be an acute threat driving declines.

A majority of projected suitable habitat for this species lies within protected areas (UNEP-WCMC and IUCN 2023) or comprises forest that is, at least for now, rugged and remote enough to resist human exploitation. Over the past three generations (11.61 years: 2011-2023), forest cover in this species' range has reduced by c.5-7% (depending on the assumptions used) (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein). Translating this into rates of population decline is obfuscated by imperfect knowledge on (1) its occupancy/density within its range; (2) the extent to which trapping is a threat; and (3) the impact of habitat degradation. None of these considerations, however, are thought likely to mean the rate of decline is being substantially underestimated, but to account for the inherit uncertainties underlying the calculations used, the rate of population decline over the past three generations is set to 2-15%, with a best guess of 5-10%. Future rates of population decline are even more difficult to predict, but are suspected to be the same as those in the past in the absence of any indication that threats will lessen or intensify.
