Justification of Red List category
This species appears to have declined as a result of predation by introduced rats, exacerbated by habitat destruction and degradation through invasion of exotic weeds. Formal surveys have failed to find any in the last two decades. There have been a number of other reports during 1978-2005, however a three-week survey in 2009 failed to find the species and estimated a 90% chance that the species is functionally extinct (Dutson 2013). A tiny population may however remain and therefore it is treated as Critically Endangered.
