Population justification: Any surviving population assumed to be tiny (numbering fewer than 50 individuals and mature individuals), with no confirmed recent reports, despite several weeks of surveys.
Trend justification: The paucity of recent confirmed sightings make it difficult to estimate a population trend, and as such the trend is essentially unknown.
