Seaside centipede lichen (Heterodermia sitchensis) COSEWIC assessment and status report: chapter 9

Existing Protection or Other Status Designations

Ten extant populations of H. sitchensis are known fromCanadaat the present time.  Of these, five are located in Pacific Rim National Park Reserve, and hence receive protection under the National Parks Act (John McIntosh, pers. comm.). The remaining five populations are situated on crown land, and for this reason are at least theoretically at risk of disturbance by logging and shoreline development.

NatureServe has accorded H. sitchensis a G2G3 rank, indicating that this species may be somewhat secure on a global scale. Actually the NatureServe rank is based on a rather optimistic S2S3 ranking by the British Columbia Conservation Data Centre (BC CDC). Here it can be noted that the BC CDC has subsequently withdrawn its lichen rankings, pending further study (Jennifer Penny, pers. comm.).  By contrast, Goward et al. (1998) accorded H. sitchensis an S1 rank for British Columbia , while the Oregon Natural Heritage Program also lists it as S1.
