Population justification: A number of recent records have extended the known range of this species and provoked an increase in the population estimate from the precautionary range of 50-249 mature individuals. The new estimate of 250-2,499 mature individuals may still be conservative, given the species's range, and further study is needed. It equates to roughly 350-4,000 individuals in total. |
|
Trend justification: An unquantified population decline is suspected to have occurred over the last 15 years on the basis of rates of habitat loss, and its known disappearance from the type locality. |
