Population justification: The population is estimated to number 250-999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: An on-going moderate population decline is suspected on the basis of rates of habitat loss, given that this species is definitely rare in degraded forest and therefore must be suffering a continuing decline as forest continues to be logged and otherwise degraded across the lowlands of its range.
