| 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: The population is suspected to be in decline at an unquantified rate, owing to habitat loss or alteration, although it is not known what processes might be limiting the species's abundance or causing declines, and this requires detailed study. | ||||
