Population justification: Any remaining population is assumed to be tiny (numbering fewer than 50 individuals and mature individuals), with no definite records since 1873, and the results of recent targeted surveys concluding that it is extinct (Butler 2012, Pratt and Mittermeier 2016).

Trend justification: With no definite records since 1873, the population trend is essentially unknown.
