Small-flowered tonella (Tonella tonella) COSEWIC assessment and status report: chapter 10
Existing Protection or Other Status
International status
Tonella tenella is not covered under the Convention on International Trade in Endangered Species of wild Fauna and Flora (CITES), the Endangered Species Act (USA) or the IUCN Red Data Book. NatureServe (2002) has designated a global rank of "G5" for the species, a ranking that indicates, on a global scale, it is considered to be "common to very common; demonstrably secure and essentially ineradicable under present conditions".
National and provincial status
Tonella tenella has been given a national rank of “N1.” The British Columbia Ministry of Sustainable Resource Management Conservation Data Centre ranks T. tenella as an S1 or a “red-listed” species in British Columbia. This is the most critical rank that can be applied to species at the provincial level and indicates that the species is "critically imperiled because of extreme rarity (typically five or fewer occurrences or very few remaining individuals) or because of some factor(s) making it especially vulnerable to extirpation or extinction".
British Columbia does not have specific legislation in place for the protection of vascular plants at risk.
