Year Published: 2008
Date Assessed: 2008-01-01

Reviewer(s): Stuart, S.N., Chanson, J.S., Cox, N.A. & Young, B.E.
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is common and reasonably adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
