Population justification: The global population size has not been quantified, but based on observations the species appears to be locally common.

Trend justification: The species is suspected to be undergoing a slow rate of decline, as, although large sections of its range may be protected by the Phou Hinpoun and Hin Namno National Protected Areas, populations outside these areas are likely to be declining owing to quarrying, hunting and habitat degradation caused by livestock grazing and firewood collection (Woxwold et al. 2009; J. Pilgrim in litt. 2009).
