A list of vascular plant species in the Nova Scotia flora Home Page | Tools Page AFTER the page below was posted, The Atlantic Canada Conservation Data Centre posted their authoritative lists of Species Ranks for vascualar and non-vascular plants and for invertebrate and vertebrate animals for each of the Atlantic Provinces. See ACCDC Species Ranks. The page below remains posted for the time-being, but visitors are advised that the ACCDC Species Ranks pages are the better ones to consult. A list of native and naturalized vascular plant species in Nova Scotia was generated from Wild Species 2005: The General Status of Species in Canada using the General Status Search Tool. See Wild Species 2005:General Status Summaries:Vascular Plants for details about the listings. The Report parameters were: Report: "Ferns (2005), Orchids (2005), Vascular Plants (2005)" Status: "At risk, May be at risk, Sensitive, Secure, Undetermined, Not assessed, Exotic" Range: "NS" A total of 1657 records matched those criteria. The conservation rankings and number of species within each rank were as follows: Rank Description No. Species 1 At Risk 8 2 May Be At Risk 127 3 Sensitive 136 4 Secure 694 5 Undetermined 96 6 Not Assessed 0 7 Exotic 596 The list is convenient for looking up scientific names of species for which you have a common name or vice versa, also to see a list of all species within a family. Use your browser's FIND function to find a name within the page. Limitations Please note that only one common name for each species is given, also that synonyms for the scientific names are not listed. Further the list is not complete, e.g., there seem to be some Atlantic Coastal Plain species missing; varieties and subspecies are not cited in the Wild Species 2005 generated lists, nor are taxonomic authorities. There are a few spelling errors in the list below (carried over from the Wild Species 2005 generated lists); these will be corrected as they are discovered. Current nomenclature and conservation ranks Current nomenclature for the listed species can be checked using ITIS. Wild Species 2005 generated lists are based on NatureServe listings for 2003. Current conservation ranks can be checked using NatureServe Explorer and/or the General Status Ranks of Wild Species in Nova Scotia; see also NS Endangered Species Act: Legally Listed Species.
