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.
