Canadian Species at Risk (including May 2005)


Table 9. Species considered by COSEWIC and placed in the Data Deficient category because of insufficient scientific information at the time of assessment. The range of occurrence (by province, territory or ocean) and date of last assessment are shown. Note that species in the Data Deficient category will normally only be reassessed if new information suggests that the species is at risk (Extirpated, Endangered, Threatened or Special Concern), or Extinct (39 species).
