Species Profile

Wolverine

Scientific Name: Gulo gulo
Taxonomy Group: Mammals
COSEWIC Range: Yukon, Northwest Territories, Nunavut, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, Newfoundland and Labrador
COSEWIC Assessment Date and Status Change: May 2014
COSEWIC Status: Special Concern
COSEWIC Status Criteria:
COSEWIC Reason for Designation: This wide-ranging carnivore has an estimated Canadian population likely exceeding 10,000 mature individuals. Although population increases appear to be occurring in portions of the Northwest Territories, Nunavut, Manitoba and Ontario, declines have been reported in the southern part of the range, e.g. in British Columbia, and populations in a large part of the range (Quebec and Labrador) have not recovered. The species may be extirpated from Vancouver Island. Population estimates are very limited, and trends are not known. Most data are limited to harvest records, and harvest levels may be under-reported because many pelts used domestically are not included in official statistics. There is no evidence, however, of a decline in harvest over the last 3 generations. This species’ habitat is increasingly fragmented by industrial activity, especially in the southern part of its range, and increased motorized access increases harvest pressure. Climate change is likely impacting animals in the southern part of the range, and this impact is expected to increase northward. The species has a low reproductive rate, is sensitive to human disturbance, and requires vast secure areas to maintain viable populations.
COSEWIC History of Status Designation: The species was considered a single unit and designated Special Concern in April 1982. Split into two populations in April 1989 (Western and Eastern populations). The original designation was de-activated. In May 2014, the Eastern and Western populations were considered as a single unit across the Canadian range and was designated Special Concern.
SARA Status: Schedule 1, Special Concern
Date of Listing (yyyy-mm-dd): 2018-05-30

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 Wolverine Gulo gulo in Canada (2015-01-06)

    Wolverines are a stocky, medium-sized carnivore and the largest terrestrial member of the weasel family. They have long, glossy coarse fur, which varies from brown to black, often with a pale facial mask and stripes running laterally from the shoulders, crossing just above the tail. The skull structure is robust, allowing it to crush and consume bones and frozen carcasses. Adult males weigh 13 to 18 kg and adult females weigh 7.5 to 12.5 kg.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2013-2014 (2014-10-15)

    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, 2013 to September, 2014) from November 24 to November 29, 2013 and from April 27 to May 2, 2014. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 56 wildlife species. The wildlife species assessment results for the 2012-2013 reporting period include the following: Extinct: 0 Extirpated: 0 Endangered: 23 Threatened: 12 Special Concern: 20 Data Deficient: 0 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 25 of those wildlife 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 - January 2015 (2015-01-13)

    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 byApril 15, 2015, for terrestrial species undergoing normal consultationsand byOctober 15, 2015, 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

  • Environment and Climate Change Canada’s Species at Risk Act (SARA) Listing Plan 2016 to 2018 (2017-09-29)

    The status of wildlife species is assessed by an independent panel of expert Canadian scientists, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). 149 terrestrial species were assessed as at-risk by COSEWIC between 2009 and 2016 and are eligible for listing under the Species at Risk Act (SARA) to be considered by the Governor-in-Council (GIC) on the recommendation of the Minister of the Environment: 86 species would be new additions, 54 currently listed species would be reclassified and 9 species would be updated to reflect changes in their recognized designatable units. A three-year listing plan has been developed to address all 149 terrestrial species and listing decisions for most species are anticipated by the end of 2018. Making amendments to Schedule 1 of SARA is a two-step process. The first step is for the GIC to propose an amendment through an order in council published in the Canada Gazette, Part I, for a 30-day public comment period. The second step is for the GIC to make a final decision on whether or not to make amendments to Schedule 1 of SARA, taking into consideration comments received during the 30-day public comment period. The amendments are made through an order in council published in the Canada Gazette, Part II. Both orders are accompanied by a Regulatory Impact Analysis Statement (RIAS) which presents the implications of listing the species or changing their status. Publishing this plan on the Species at Risk Public Registry is intended to provide transparency about the Government of Canada’s plan to make listing decisions under the Species at Risk Act. NOTE: The information presented below is intended to provide openness and transparency with respect to when terrestrial species might be considered for listing under Schedule 1 of the Species at Risk Act. It is intended to assist anyone who may wish to provide comments on such listing considerations. Given any number of factors can affect the timing of a listing decision; the Plan is subject to change. Accordingly, the Plan will be periodically updated.
