Species Ranks

The Atlantic CDC maintains comprehensive lists of plant and animal species, with a rarity rank and legal status for each.  These lists, the result of collaboration with regional experts, aid the development of sub-national rarity ranks (S-ranks).  To date, the Atlantic CDC has compiled S-ranks for most vascular plant and vertebrate animal species and for some non-vascular plant and invertebrate species.

Through the links  below you can access lists of species, including rare species, for each Atlantic province. Lists are organized by province and by taxonomic group. Newfoundland and Labrador are treated separately for ecological reasons.
