Areas for Plant Conservation should fulfill the dual goals of including both highly
restricted range (“rare”) species
and widespread species, thus achieving
maximum representativeness. One consequence of the high correlation between species richness and range size rarity is
that the rare species
should be good predictors of species richness. In other words, the areas of high endemism should collectively encompass the
total species richness.
