| Generation length (yrs) | 4.2 | - | - | - |
| 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: This species appears to have been lost from parts of its former range and is suspected to be declining slowly, owing to habitat alteration and fragmentation. | ||||
