About COSEWIC

COSEWIC mandate

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assesses the national status of wild species, subspecies, varieties, or other designatable units that are considered to be at risk in Canada. Designations are made on native wildlife species including the following taxonomic groups: mammals, birds, reptiles, amphibians, fishes, arthropods, molluscs, vascular plants, mosses, and lichens.

COSEWIC membership

COSEWIC comprises members from each provincial and territorial government wildlife agency, four federal agencies (Canadian Wildlife Service, Parks Canada Agency, Department of Fisheries and Oceans, and the Canadian Museum of Nature), three non-government science members, two early career members and the co-chairs of the species specialist and the Aboriginal Traditional Knowledge subcommittees.

Definitions

The following definitions are used by COSEWIC:

Wildlife species: A species, subspecies, variety, or geographically or genetically distinct population of animal, plant or other organism, other than a bacterium or virus, that is wild by nature and is either native to Canada or has extended its range into Canada without human intervention and has been present in Canada for at least 50 years.
Extinct (X): A wildlife species that no longer exists.
Extirpated (XT): A wildlife species no longer existing in the wild in Canada, but occurring elsewhere.
Endangered (E): A wildlife species facing imminent extirpation or extinction.
Threatened (T): A wildlife species likely to become endangered if limiting factors are not reversed.
Special concern (SC)*: A wildlife species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats.
Not at risk (NAR)**: A wildlife species that has been evaluated and found to be not at risk of extinction given the current circumstances.
Data deficient (DD)***: A category that applies when the available information is insufficient (a) to resolve a species’ eligibility for assessment or (b) to permit an assessment of the species’ risk of extinction.

*: Formerly described as “Vulnerable” from 1990 to 1999, or “Rare” prior to 1990.
**: Formerly described as “Not In Any Category”, or “No Designation Required.”
***: Formerly described as “Indeterminate” from 1994 to 1999 or “ISIBD” (insufficient scientific information on which to base a designation) prior to 1994. Definition of the (DD) category revised in 2006.

COSEWIC assessment results

The tables that follow (tables 6-9) are organized by status category and then by taxonomic group. For each wildlife species, the information provided includes the common name, scientific name, population name, and range of occurrence in Canada (by province, territory or ocean). The most recent date of COSEWIC assessment is shown. The symbols on the left provide information on the outcome of reviews of classification (see explanation of symbols on page three).

The first COSEWIC "Endangered Wildlife Species List" was issued in 1978. In 1990, it was decided that all wildlife species considered by COSEWIC should be included in this document even if the wildlife species were in the Not at Risk or Data Deficient categories. Therefore, this document is divided into four sections. The first section (Table 6) includes wildlife species assessed and designated as Extinct. The second section (Table 7) includes wildlife species assessed and designated as Extirpated, Endangered, Threatened or Special Concern. The third section (Table 8) includes wildlife species assessed and found to be in the Not at Risk category. The fourth section (Table 9) includes wildlife species considered by COSEWIC and placed in the Data Deficient category because of insufficient scientific information to resolve a wildlife species' eligibility for assessment or to assess risk of extinction.

Information used for assessment

COSEWIC uses the best available information when assessing the status of a wildlife species, usually summarized in a COSEWIC status report. Assessments involve consideration of several factors, including the wildlife species’ eligibility for assessment and the status suggested by application of the quantitative COSEWIC criteria (adapted from those used by the International Union for the Conservation of Nature, IUCN). Further information on status reports and the assessment process may be found on the COSEWIC website:Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

Range of occurrence

The geographical distribution of each wildlife species is defined in terms of the provinces, territories and oceans in which the wildlife species occurs. This information should not be treated as a complete listing of the jurisdictions that may be legally responsible for the conservation and management of a wildlife species. Several guidelines are followed when determining the range of occurrence of a wildlife species: for birds, it includes the Canadian breeding and wintering distribution; for marine species, it includes the oceans in which the species occurs (Arctic, Pacific or Atlantic); for freshwater species, it includes the province or territory in which the waterbody occurs; and, for species that occur in brackish waters, move between marine and freshwater environments, or move between oceans and land (for example, Atlantic Walrus), range of occurrence includes a list of both the oceans and provinces in which the wildlife species occurs.

About the legal listing of wildlife species assessed by COSEWIC

COSEWIC meets twice a year to assess the status of wildlife species. Since 2004, COSEWIC submits an annual report to the federal Minister of the Environment and Climate Change, which includes all assessment results for wildlife species that COSEWIC has assessed since its last report.

Wildlife species assessed by COSEWIC as Extirpated, Endangered, Threatened or Special Concern will be considered for legal protection and recovery (or management) under the SARA. Based in part on COSEWIC's status assessment, the government may decide to add a wildlife species to SARA's List of Wildlife Species at Risk, to not add a wildlife species to the List of Wildlife Species at Risk, or to refer the matter back to COSEWIC for further information or consideration.

More information on the SARA listing process may be found on the SARA Public Registry. Species at risk public registry

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) was created in 1977 as a result of a recommendation at the Federal-Provincial Wildlife Conference held in 1976.

It arose from the need for a single, official, scientifically sound, national classification of wildlife species at risk. In 1978, COSEWIC designated its first wildlife species and produced its first list of Canadian wildlife species at risk.

In 2002, COSEWIC celebrated 25 years of science-based assessment of the status of wildlife species at risk in Canada.

On June 5th 2003, the Species at Risk Act (SARA) was proclaimed. SARA establishes COSEWIC as an advisory body, ensuring that wildlife species will continue to be assessed using the best available scientific, community, and Aboriginal Traditional Knowledge.

The Aboriginal Traditional Knowledge (ATK) Subcommittee held its inaugural meeting in February 2006. Members of the ATK Subcommittee act as facilitators and resource people and, when possible, collaborate with Indigenous communities to respectfully gather information from Knowledge Holders and Resource Users following their ATK Process and Protocols Guidelines. The ATK Subcommittee is working to ensure that the best available Indigenous Knowledge is available for the wildlife species assessment process.

Even after over forty years of existence, COSEWIC continues to evolve and to fine-tune its operations in an effort to do its job in the best possible manner.

The Canadian Wildlife Service, Environment and Climate Change Canada, provides full administrative and financial support to the COSEWIC Secretariat.
