Grand coulee owl-clover (Orthocarpus barbatus) COSEWIC assessment and status report: chapter 12

Existing protection or other status

International status

Orthocarpus barbatus 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. NatureServe has designated a G2G4 rank for the species (NatureServe Explorer, 2003) also lists the species as having a rounded global rank of G3. The latter rank indicates that the species is classified as "rare or uncommon (typically 21-100 occurrences); may be susceptible to large-scale disturbances; e.g., may have lost extensive peripheral populations”.

This species is not tracked as a rare species outside of British Columbia and is ranked S? in Washingtonby NatureServe Explorer (2003). The S? rank indicates that the species has yet to be ranked.

National and provincial status

Since the species is restricted to British Columbia, Canada, it has a national rank of N1. Provincially,Orthocarpus barbatus is ranked by the British Columbia Conservation Data Centre as S1 and appears on the British Columbia Ministry of Sustainable Resource Management red list (Douglas et al. 2002). This S1 rank 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".

There is currently no specific endangered species legislation in place for the protection of vascular plants in British Columbia that have been placed on the Ministry of Sustainable Resource Management red list. The largest population of Orthocarpus barbatus in British Columbia, however, is protected by the Provincial Park Act.
