Population justification: The population is estimated to number fewer than 50 individuals and mature individuals, based on analyses of recent searches and reports, the extent of habitat destruction within its range, and the conclusion that it seems likely that any surviving population will prove minute.
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
