Justification of Red List category
This species is listed as Near Threatened because it is thought to have a moderately small population, which is expected to undergo a moderately rapid decline over the next three generations owing to the clearance and degradation of forest at middle elevations. Any evidence that the population is smaller, or declining more rapidly, might qualify the species for uplisting to a higher threat category.
