Population & trend

  Estimate Data quality Derivation Year of estimate

Population trend Unknown -

Largest subpopulation - - -
Generation length (yrs) 6.5 - - -
Population justification: Any remaining population is assumed to be tiny (numbering fewer than 50 individuals and mature individuals) based on the lack of confirmed records since 1956; analyses of remaining habitat indicate that no tracts remain which are large enough to support the species.
