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 Proud Globelet Patera pennsylvanica in Canada (2016)

    Proud Globelet, Patera pennsylvanica is a terrestrial snail in the family Polygyridae. The yellowish, round shell (15-20 mm diameter) lacks a tooth-like protuberance at the shell opening compared to other species of the genus. The sole known Canadian population occurred in and near the Black Oak Heritage Forest owned by the City of Windsor. Although the ecological significance of Proud Globelet is unknown, gastropods, in general, play important roles in forest ecosystem functioning via nutrient cycling and soil building processes.

Response Statements

  • Response Statement - Proud Globelet (2015)

    This large terrestrial snail is found in the upper mid-west of North America, with Canada’s single recorded occurrence in and near a wooded park in Windsor, Ontario. General snail surveys conducted throughout southern Ontario over the last century have not detected this species anywhere else. Freshly dead shells were found in 1992 and 1996 but only dead, weathered shells were found in extensive surveys in 2013. Human intrusions and disturbances from recreational activities and ecosystem modifications from invasive plants and animals, the surrounding urbanization, pollution from local and regional sources, and climate change may have contributed to the species’ demise; it appears another native snail disappeared from the same area at the same time.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2014-2015 (2015)

    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, 2014 to September, 2015) from November 23 to November 28, 2014 and from April 27 to May 1, 2015. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 56 wildlife species. The wildlife species assessment results for the 2014-2015 reporting period include the following: Extinct: 0 Extirpated: 1 Endangered: 21 Threatened: 11 Special Concern: 21 Data Deficient: 1 Not at Risk: 1 Total: 56 Of the 56 wildlife species examined, COSEWIC reviewed the classification of 40 that had been previously assessed. The review of classification for 24 of those wildlife species resulted in a confirmation of the same risk status as the previous assessment.

Consultation Documents

  • Consultation on Amending the List of Species under the Species at Risk Act : Terrestrial Species - January 2016 (2016)

    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. Extirpated, Endangered and Threatened species on Schedule 1 benefit from the protection of prohibitions and recovery planning requirements under SARA. Special Concern species benefit from its management planning requirements. Schedule 1 has grown from the original 233 to 521 wildlife species at risk. Please submit your comments byMay 4, 2016, for terrestrial species undergoing normal consultationsand byOctober 4, 2016, for terrestrial species undergoing extended consultations.For a description of the consultation paths these species will undergo, please see:Species at Risk Public Registry website
