COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Riverine Clubtail Stylurus amnicola in Canada (2013)

    Riverine Clubtail (Stylurus amnicola) is a dragonfly in the clubtail family. Members of the genus Stylurus are referred to as “hanging clubtails” for their habit of hanging vertically when perched on streamside vegetation. It is a small (47-49 mm long), slender dragonfly, with a prominent club at the end of the abdomen. The front of the thorax has a distinctive three-pointed star that distinguishes this species from other hanging clubtails. The abdomen is blackish with small yellow spots along the top and prominent yellow spots on the sides near the tip. Females have yellow patches along the sides of the abdomen. The hind legs are mostly black. The larvae are distinguished by their small size and shape of the abdominal segments and mouth parts. This species may serve as a useful environmental indicator.

Response Statements

  • Response Statement - Riverine Clubtail, Great Lakes Plains population (2013)

    This dragonfly population is restricted to two small creeks that flow into Lake Erie. The impact of a variety of threats was determined to be very high, suggesting that there may be a substantial decline over the next decade. The threats include water withdrawal from the streams, pollution, and invasive alien species of fish that would feed on dragonfly larvae.

COSEWIC Annual Reports

  • COSEWIC Annual Report – 2012-2013 (2013)

    Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”. COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2012 to September 2013) from November 25 to November 30, 2012 and from April 28 to May 3, 2013. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 73 wildlife species. The wildlife species assessment results for the 2012-2013 reporting period include the following: Extinct: 0 Extirpated: 2 Endangered: 28 Threatened: 19 Special Concern: 19 Data Deficient: 4 Not at Risk: 1 Total: 73 Of the 73 wildlife species examined, COSEWIC reviewed the classification of 50 species that had been previously assessed. The review of classification for 26 of those species resulted in a confirmation of the same status as the previous assessment.

Consultation Documents

  • Consultation on Amending the List of Species under the Species at Risk Act: Terrestrial Species – December 2013 (2013)

    The Government of Canada is committed to preventing the disappearance of wildlife species at risk from our lands. As part of its strategy for realizing that commitment, on June 5, 2003, the Government of Canada proclaimed the Species at Risk Act (SARA). Attached to the Act is Schedule 1, the list of the species provided for under SARA, also called the List of Wildlife Species at Risk. Endangered or Threatened species on Schedule 1 benefit from the protection of prohibitions and recovery planning under SARA. Special Concern species benefit from its management planning. Schedule 1 has grown from the original 233 to 518 wildlife species at risk. Please submit your comments by March 23, 2014, for terrestrial species undergoing normal consultations and by October 23, 2014, for terrestrial species undergoing extended consultations.
