Rayless goldfields (Lasthenia glaberrima) COSEWIC assessment and status report 2000: chapter 10

Existing Protection or Other Status Designations

Lasthenia glaberrima is not covered under the Convention on International Trade in Endangered Species (CITES), the Endangered Species Act (USA) or the IUCN Red Data Book. NatureServe globally ranks it as G5 (secure). The Washington State Natural Heritage Program (Washington natural Heritage Program 2005) ranks it as S1 (critically imperilled) in their state. The Oregon Natural Heritage Information Center lists the species as SNR (not ranked) but had considered placing it on the state Review List. They decided against this because it is very abundant in some places such as Lane County in the southern Willamette Valley (Vrilakas pers. comm. 2003). It is also ranked SNR in California (NatureServe 2005).

In British Columbia, it is currently ranked as S1 (critically imperiled). It does not occur elsewhere in Canada. The British Columbia Conservation Data Centre also places it on the provincial Red List, which consists of species that are provincially threatened or endangered (B.C. Conservation Data Centre 2005). British Columbia does not provide any legal protection for Lasthenia glaberrima.
