Justification of Red List category
This species is classified as Critically Endangered because it has a tiny population. Numbers fluctuate owing to extreme weather, and in 2008 the population increased to be above the Critically Endangered threshold. If the population remains at this level for more than five years, or if reintroduction efforts prove successful, the species may be downlisted in the future.
