Population justification: The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. However, further work is needed to refine this estimate, as it has been suggested that the total population may now be as low as 2,000 individuals (D. Kimani in litt. 2009).

Trend justification: The population is suspected to be in rapid decline owing to the human-driven loss of tussock grasslands. The rate of decline is expected to become very rapid over the next three generations.
