Brook spike-primrose (Epilobium torreyi) COSEWIC assessment and status report: chapter 10
Existing Protection or Other Status Designations
Epilobium torreyi is not covered under the Convention on International Trade in Endangered Species (CITES), the Endangered Species Act (USA) or the International Union for Conservation of Nature (IUCN) Red Data Book. It is ranked globally as G5: demonstrably widespread, abundant and secure. The Montana Natural Heritage Program ranks it as SH (historic, possibly extirpated) in their state. Epilobium torreyi is ranked SNR (reported without comment) in California, Idaho, Nevada, Oregon and Washington (NatureServe 2004).
In British Columbia, it is currently ranked as S1 (critically imperiled); however, its rank may soon be revised to SH based on the most recent surveys (J. Penny, pers. comm. 2004). Its national rank in Canada is N1 (NatureServe 2004) and that rank should be revised in accordance with the BC rank as it does not occur in any other province or territory. British Columbia does not provide any legal protection for Epilobium torreyi.
