Environment Canada, in partnership with NatureServe Canada, recently undertook a massive species ranking assessment for all species groups in Canada. The result is a comprehensive, updated look at the status of species in Canada. The SKCDC has finished reviewing the reassessments for vascular plants and has now posted the changed S-ranks. Updates for other groups (animals, invertebrates, non-vascular plants, etc.) are ongoing.
The following list of species is of interest as these taxa have now been added to the tracking list. For the full list of current taxa ranks, and for the final authority, please see the lists provided on our lists page. For the convenience of our users, we have added the rank reassessment and rank change dates into the excel files of our species lists. This will allow users to sort the data and view the most recently assessed taxa.
For more information on the ranking process, please see our ranking page. If you have a plant taxon that you believe should be a priority for a rank reassessment, please contact the SKCDC botanist.
