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

DEFINITIONS

The following definitions were reviewed by COSEWIC in April 2009:

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 it 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 wildlife 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 wildlife species' eligibility for assessment or (b) to permit an assessment of the wildlife 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.

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 by COSEWIC is shown. The symbols on the left provide information on the type of status report used as the basis for assessment (see below), and the symbols on the right provide information on the outcome of status reassessments (see explanation of reassessment 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, the status report is the source of this information. However, sometimes, such as in an emergency assessment for a wildlife species that is at great risk of extirpation or extinction, there is not sufficient time to allow for the preparation of a COSEWIC status report. In such situations, the best available information, if deemed acceptable and sufficient, will be used to assess status. Emergency assessments are denoted in this booklet with an exact date of assessment and, if the emergency assessment is not based on a status report, with a closed triangle at the left of the wildlife species' name.

There are three basic types of status report used by COSEWIC during its normal assessment process: new, update and existing. In most cases, an assessment is made using a new or update status report on a wildlife species. New reports are a summary of the best available information that is relevant to the assessment of the conservation status of a wildlife species. Every 10 years or earlier if warranted, COSEWIC reassesses wildlife species previously designated in a category of risk with an update status report. COSEWIC also may use an update report to reassess other wildlife species previously assigned to the Not at Risk or Data Deficient categories. Finally, some wildlife species have been reassessed by COSEWIC based on an existing status report, with the express goal of applying new quantitative criteria that were first implemented by COSEWIC in October 1999. These quantitative criteria are in use by COSEWIC as an aid in assessing a wildlife species' risk of extinction, and are based on the quantitative criteria used by the World Conservation Union (IUCN).

Further information on status reports and the assessment process may be found on the COSEWIC website: www.cosewic.gc.ca.

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

p Assessment based on information other than a COSEWIC status report that was deemed adequate for wildlife species assessment (e.g., supporting documentation accompanying a request for emergency assessment). Assessment was done after implementation of the quantitative criteria (October 1999 or later).
∆ Assessment based on a new status report or an update status report. Assessment was done after implementation of the quantitative criteria (October 1999 or later).
∆ or ∆+ Wildlife species re-assessed using an existing status report. A plus sign (+) indicates the report has an addendum or that the report has been modified. Assessment was done after implementation of the quantitative criteria (October 1999 or later).
blank Assessment based on a new status report or an update status report. Assessment was done before the implementation of the quantitative criteria (prior to October 1999).

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 (e.g., 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 at least once a year to consider status reports on candidate wildlife species. Since 2004, COSEWIC submits its annual report to the federal Minister of the Environment in late summer. The annual report 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 COSEWIC web site (www.COSEWIC.gc.ca; FAQ section and About Us section) or on the SARA Public Registry (www.sararegistry.gc.ca).
