This publication is printed once per year, after the spring COSEWIC meeting. The website version of this document (www.cosewic.gc.ca/eng/sct0/rpt/rpt_csar_e.cfm) includes minor revisions to COSEWIC information and updates to the Legal Listing field (SARA). This publication can be cited as follows: COSEWIC. 2005. Canadian Species at Risk. Committee on the Status of Endangered Wildlife in Canada. 64 pp.

COSEWIC Status Reports are available from the Species at Risk Act Public Registry http://www.sararegistry.gc.ca

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 species including the following taxonomic groups: mammals, birds, reptiles, amphibians, fishes, arthropods, molluscs, vascular plants, mosses, and lichens.

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 Federal Biodiversity Information Partnership, chaired by the Canadian Museum of Nature), three members at large and the co-chairs of the species specialist and the Aboriginal Traditional Knowledge subcommittees. The Committee meets to consider status reports on candidate species.

The following definitions were reviewed by COSEWIC in May 2004:

* 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.

Species designated in the "risk" and the Extinct categories, as well as the Not at Risk and Data Deficient categories

Summary of COSEWIC’s assessment results for the “risk” categories (Extirpated, Endangered, Threatened and Special Concern) (487 species) and for the Extinct category (13 species). The results include the May 2005 meeting.

The tables that follow (Tables 6-9) are organized by status category and then by taxonomic group. For each 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 assessment by COSEWIC is shown. The symbols on the left provide information on the type of status report used as the basis for reassessment for species evaluated against quantitative criteria (see below), and the symbols on the right provide information on the outcome of status reassessments (see explanation of symbols on page three).

The first COSEWIC "Endangered Species List" was issued in 1978. In 1990, it was decided that all species considered by COSEWIC should be included in this document even if the 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 species assessed and designated as Extinct. The second section (Table 7) includes species assessed and designated as Extirpated, Endangered, Threatened or Special Concern. The third section (Table 8) includes species assessed and found to be in the Not at Risk category. The fourth section (Table 9) includes species considered by COSEWIC and placed in the Data Deficient category because of insufficient scientific information.

COSEWIC has been using quantitative criteria to assess species' risk of extinction since October 1999. These criteria were adapted from the criteria used by the World Conservation Union (IUCN).

Explanation of type of status report symbols for species evaluated using quantitative criteria:

∆ or ∆+ Assessment based on a new status report or an update status report. A plus sign (+) indicates the report has an addendum or that the report has been modified.
[] or []+ Species re-assessed using an existing status report. A plus sign (+) indicates the report has an addendum or that the report has been modified.

The geographical distribution of each species is defined in terms of the provinces, territories and oceans in which the 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 species. Several guidelines are followed when determining the range of occurrence of a 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 (e.g., Atlantic Walrus), range of occurrence includes a list of both the oceans and provinces in which the species occurs.

Abbreviations for provinces and territories:
AB Alberta NS Nova Scotia QC Québec
BC British Columbia NT Northwest Territories SK Saskatchewan
MB Manitoba NU Nunavut YT Yukon Territory
NB New Brunswick ON Ontario
NL Newfoundlandand Labrador PE Prince Edward Island

COSEWIC meets at least once a year to consider status reports on candidate species. Since 2004, COSEWIC submits its annual report to the federal Minister of the Environment in late summer. The annual report includes all species that COSEWIC wishes to have considered for legal listing.

Species assessed by COSEWIC as Extirpated, Endangered, Threatened or Special Concern will be considered for legal protection and recovery (or management) under the Species at Risk Act (SARA). Based in part on COSEWIC's status assessment, the government may decide to add a species to SARA's List of Wildlife Species at Risk (Legal List), to not add a species to the Legal List, 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 COSEWIC web site (www.COSEWIC.gc.ca; FAQ section and About Us section) or on the SARA Public Registry (www.sararegistry.gc.ca).

The following symbols are used in Table 7 (SARA field) to denote the stage of species assessed by COSEWIC within the SARA listing process at the time that this publication was produced (1 September 2005).

* COSEWIC status assessment not yet forwarded to the Minister.
** COSEWIC status assessment has been forwarded to the Minister of the Environment; a decision is pending.
1 Species on Legal List.
2a Species not added to Legal List.
2b Species not added to Legal List (pending further consultation by government).
3 Referred back to COSEWIC for further information or consideration.

A short history is provided for each species that has been reassessed by COSEWIC, including date(s) of assessment and the status assigned. In October 1999 COSEWIC began using quantitative criteria to augment the earlier method of using status definitions to assign status. For species assessed since October 1999, the type of status report used as the basis for reassessment is indicated. Update reports focus on changes in the biological and threat information that has become available since the last time a report was prepared. For some species, COSEWIC deemed the existing report suitable for reassessment.

COSEWIC Logo

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 species and produced its first list of Canadian species at risk.

In 2002, COSEWIC celebrated 25 years of science-based assessment of the status of 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 species will continue to be assessed under a rigorous and independent scientific process.
