Critical Habitat Orders

Critical Habitat of the Western Brook Lamprey (Lampetra richardsoni) Morrison Creek Population Order

The Western Brook Lamprey – Morrison Creek Population (Lampetra richardsoni) is a small freshwater fish endemic to the Morrison Creek watershed on eastern Vancouver Island, British Columbia. The species has a rare life history in which both a parasitic (L. richardsoni var. marifuga) type and a non-parasitic (L. richardsoni) type are produced. No quantitative population estimates exist for the Morrison Creek Lamprey; however, catch rates of the parasitic type of Morrison Creek Lamprey have decreased over the past 30 years. In April 1999, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the Morrison Creek Lamprey as a threatened species. In May 2000, COSEWIC reassessed the species as an endangered species. In June 2003, the Morrison Creek Lamprey was listed as endangered on the List of Wildlife Species at Risk (Schedule 1, Part 2) of the Species at Risk Act (SARA). COSEWIC re-examined and confirmed the assessment of endangered in April 2010, and renamed the species Western Brook Lamprey – Morrison Creek Population (Lampetra richardsoni). Hereinafter, the species will be referred to as the “Morrison Creek Lamprey.”
