Population
Estimate Data quality Derivation Year of estimate
Population size 1-49 mature individuals poor estimated 2000
Population trend unknown - - -
Generation length 2.98 years - - -
Number of subpopulations 1 - - -
Percentage of mature individuals in largest subpopulation 100% - - -

Population justification: Any remaining population is assumed to be tiny (numbering fewer than 50 individuals and mature individuals) based on a lack of records since 1860.

Trend justification: The current population trend is unknown as the species has not been recorded since 1860 and may be extinct.
