Twisted oak moss (Syntrichia laevipila) COSEWIC assessment and status report: chapter 10

Existing Protection or Other Status

No legislation, regulations, customs, or conditions protect this species. Globally, both varieties of this species are tentatively considered vulnerable to possibly secure (G3G5T?), and they are Red-listed (S1) in British Columbia (BC Conservation Data Center 2001, Ryan 1996). In Norway it is Red-listed and considered vulnerable by Timmermann (2001). J. Christy (pers. comm., 2002) notes that Syntrichia laevipila is not currently listed for Oregon, but found only two records and suggests a G4S1 ranking (apparently globally secure and critically imperiled sub-nationally). The work of Merrifield (2000), however, shows that S. laevipila may be fairly common there. NatureServe Explorer (2002) ranks this species as G3G5 globally.
