Population justification: The species is considered rare and localised, but it is also poorly known. The population is provisionally estimated to number 1,000-2,499 individuals, but this requires confirmation. The estimate equates to 667-1,666 mature individuals, roudned here to 600-1,700 mature individuals. |
|
Trend justification: Although there is no new information on population size or trend, habitat degradation is continuing within the small range, suggesting that the population is likely to be in decline. |
