Justification of Red List categoryNow following the use of a Minimum Convex Polygon species's EOO is very large and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km
2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size may be small, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). For these reasons the species is now evaluated as Least Concern.
