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.
The American Badger (Taxidea taxus) is a medium-sized fossorial (burrowing) carnivore in the weasel (Mustelidae) family. They are well-adapted to digging, possessing a dorso-ventrally flattened body with a robust pectoral girdle and broad front paws used to excavate burrows and dig out prey. Four subspecies of American Badger are recognized, three of which occur in Canada. Mitochondrial DNA work found multiple distinct genetic groups in Canada. Four designatable units are recommended (Jeffersonii East and West, Taxus, and Jacksoni), each corresponding with the existing subspecies distribution of T. t. taxus and jacksoni, with T. t. jeffersonii divided into two DUs.
Fewer than 250 mature badgers live in the Okanagan Valley-Cariboo region where they are vulnerable to increasing threats of mortality from roadkill and habitat loss associated with the change of open areas to urban or forest environments.
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:
Special Concern: 19
Data Deficient: 4
Not at Risk: 1
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.
