Population justification: Any remaining population is assumed to be tiny (numbering fewer than 50 individuals and mature individuals), as there have been no confirmed sightings since the early 1960s.
Trend justification: The population trend of this species is unknown since the last confirmed sightings of this species occurred in the early 1960s.
