Justification of Red List category
This species is listed as Least Concern on the basis of evidence indicating that the its range and population are increasing and may have been recovering over the last two decades at least. Although it has a very small range and probably a small to moderately small population, it is showing positive trends, it is not restricted to 10 locations or less and its population comprises more than one sub-population, all of which probably exceed 1,000 individuals, and is not severely fragmented, thus it no longer approaches the thresholds for Vulnerable under any of the IUCN criteria.
3300-13000 mature individuals
