COSEWIC ASSESSMENT RESULTS

The tables that follow (Tables 6-8) are organized by status category and then by taxonomic group. An explanation of the symbols and abbreviations is provided below. 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 examination by COSEWIC is shown, and symbols provide information on the outcome of status re-examinations (e.g., uplisting, downlisting) and the basis of re-examination for species evaluated against the new quantitative criteria. For birds, range of occurrence includes the Canadian breeding and wintering distribution. 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 Not at Risk or Data Deficient. Therefore, this document is divided into three separate section. The first section (Table 6) includes species examined and designated as Extinct, Extirpated, Endangered, Threatened or Special Concern. The second section (Table 7) includes species examined and found to be in the Not at Risk category. The third section (Table 8) includes species examined and found to be in the Data Deficient category because of insufficient scientific information. All three sections include the geographical occurrence and most recent date of examination.


Explanation of symbols

Re-assessments and new species

3 Species placed in a higher risk category (uplisted) after re-examination on the date shown.
4 Species placed in a lower risk category (downlisted) after re-examination on the date shown.
5 Species stays in the same risk category (no change) after re-examination on the date shown.
0 Species moved to the Not at Risk category from a risk category (de-listed) on the date shown.
6 Species moved to the Data Deficient Category from a risk category, or to a risk category from the Data Deficient Category (changed), on the date shown.
(no arrow) New species examined on the date shown.

Evaluation with COSEWIC’s new quantitative criteria

COSEWIC has recently begun using quantitative criteria to assess species’ risk of extinction.

These criteria were adapted from the criteria used by the World Conservation Union (IUCN) and have been used by COSEWIC since October 1999.

1 or 1+  Assessment based on a new status report or an update status report. A plus sign (+) indicates the report has an addendum.
2 or 2+  Species re-assessed using an existing status report. A plus sign (+) indicates the report has an addendum or that the report has been modified.
