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: A moderately rapid and ongoing population decline is suspected to be occurring in response to continuing habitat destruction and fragmentation over the period of the last three generations. |
