Columbian carpet moss (Bryoerythrophyllum columbianum) COSEWIC assessment and status report: chapter 12
Existing Protection or Other Status
No legislation, regulations, customs, or conditions protect this species. For British Columbia, Ryan (1996) ranked Bryoerythrophyllum columbianum as critically imperiled at the provincial level (S1), whereas the BC Species and Ecosystem Explorer (2003) and NatureServe Explorer (2003) rank it as imperiled (S2). It is Red-listed in the province. Globally, BC Species and Ecosystem Explorer and NatureServe Explorer rank it as imperiled or secure (G2G4). J. Christy (pers. comm. 2002) notes six records in Oregon and ranks it vulnerable globally and imperiled in that state (G3S2), and suggests that it is S2 in Washington State, although it is common in the shrub-steppe in south-central Washington (rankings are being restructured for Washington State at this time). NatureServe Explorer also ranks it as S2 for Oregon.
J. Shevock (pers. comm. 2002) states that it is known from two occurrences in California, Lake and Colusa Counties, but a ranking was not provided. It is not listed as rare byShevock (2001) for California.
