PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Island Tiger Moth Grammia complicata in Canada (2014)

    Island Tiger Moth (Grammia complicata Walker) is a medium sized moth (wingspan 32 mm to 40 mm) in the family Erebidae, subfamily Arctiinae. The upper wing surfaces vary from dark brown-black interlaced with whitish to pale orange patterns along the wing veins; to the converse, with an orange-peach background with dark brown-black vein-like patterns. The hind wings are typically lighter than the forewings, pale orange, with brown dots towards the outer wing margins which are also brown. The head, thorax and abdomen are dark brown-black with peach-orange markings. In general, Tiger moth (Grammia spp.) larvae are up to 6 cm long, have black - orange lateral stripes and are densely covered in dark hairs. This species was recently (2009) separated from the Ornate Tiger Moth based on morphological and genetic evidence.

Response Statements

  • Response Statement - Island Tiger Moth (2013)

    This near endemic moth has a small distribution and is restricted to only 5 locations in the Georgia Basin in British Columbia.  Much of its habitat has been destroyed and the quality of what remains is declining due to ongoing residential and commercial development, recreational activities, invasive or non-native species, and vegetation succession that has changed due to disruption of former fire regimes.

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.
