Justification of Red List category
This species's population size has declined rapidly over the past three generations and it therefore qualifies as Critically Endangered. It appears from recent counts that the population is now stable, probably as a result of extensive conservation actions. If evidence continues to show that the population remains stable, the species may be downlisted to a lower category of threat in the future.
