It has been argued that the initial rarity of an animal species may be a good indicator of subsequent vulnerability. The usefulness of this argument in the conservation of endangered species has been investigated by the authors, who have compared the apparent vulnerability of certain rare animals with their actual status. The two approaches agreed substantially, but some striking differences occurred. Some rare species seem more prone to extinction than is officially recognized, and their status should be reviewed. Other species are not particularly rare, but are threatened for other biological and economic reasons. Knowledge of rarity is a good starting point, but this sould be followed by a detailed examination of other relevant factors to discern genuine risk.
