Population justification: In 2014 there were 126 individuals, including 110 breeding adults (Kakapo Recovery 2014).
Trend justification: The species was described as still abundant in Fiordland and some other parts of South Island in the early twentieth century. The current population comprises of at least 78 breeding adults, and 126 birds in total (R. J. Moorhouse in litt. 2012), so although the population is now starting to slowly increase, it has declined by >80% in the last 100 years (<3 generations) (P. Jansen in litt. 2004, D. Merton in litt. 2005, Merton 2009).
