Population justification: The population is estimated to number 2,500-9,999 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 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. |
|
Trend justification: Slow declines are suspected owing to on-going conversion of habitat around the species's lower altitudinal limit. However, although a proposal to build a road linking several hill stations within its range have been shelved, if this goes ahead in the future it would have serious impacts on the species. |
