COSEWIC ASSESSMENT RESULTS
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). For birds, range of occurrence includes the Canadian breeding and wintering distribution. 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.
Evaluation with COSEWIC's quantitative criteria
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
1 or 1+ 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.
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.
