Justification of Red List category
This species has a large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² 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 has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but the species is described as locally uncommon in the north of its range to fairly common in the south (Harris and Franklin 2000). This population is estimated to be increasing following evidence of a range expansion in the south of its distribution from the 1970s to the 1990s at least (Harris and Franklin 2000).
Trend justification
This population is estimated to be increasing following evidence of a range expansion in the south of its distribution from the 1970s to the 1990s at least (Harris and Franklin 2000).
