Recovery Strategy for the Shortnose Cisco (Coregonus reighardi) in Canada
2. Species status information
The Shortnose Cisco was formerly assessed as “Threatened” by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 1987 based on a status report by Parker (1988). In 2005, COSEWIC reassessed the species as Endangered based on an update status report (COSEWIC 2005), and the species was formally listed as such under Canada’s Species at Risk Act in 2007. The species is also listed as Endangered under Ontario’s Endangered Species Act, 2007. NatureServe (2009) ranks the species as Globally Historic (GH) and Nationally Historic (NH) in both Canada and the USA as well as Regionally Extirpated (SX) in Illinois, Indiana, New York, and Wisconsin, and Regionally Historic (SH) in Michigan and Ontario. The Shortnose Cisco is included on the International Union for Conservation of Nature (IUCN) Red List under the category of Critically Endangered (Gimenez Dixon 1996) and has been assessed as Endangered by the American Fisheries Society (Jelks et al. 2008). As there are no known extant populations throughout its historical distribution in lakes Michigan, Huron or Ontario and the last reported sighting for the species was from Lake Huron in 1985 (Webb and Todd 1995) the Shortnose Cisco is thought to be extinct (COSEWIC 2005, Jelks et al. 2008, Mandrak and Cudmore 2010).
