Species Ranks

The AC CDC maintains comprehensive provincial lists of plant and animal species, with a conservation status rank (S-rank) and legal status for each species in each province (with Newfoundland and Labrador treated separately for ecological reasons). Species’ conservation status is assessed in collaboration with other experts. AC CDC maintains S-ranks for all terrestrial vertebrates, vascular plants, bryophytes (mosses and related plants), macrolichens and for many invertebrate groups. As of June 2024 our databases have provincial ranks for over 21,900 species, subspecific taxa and ecological communities. Through the links below you can access full lists of species with conservation status ranks, for each Atlantic province. Lists are organized by jurisdiction and by taxonomic group.
