Wolverine occur throughout the Yukon. They are widely distributed across the Yukon North Slope.
The size or density of the wolverine population on the Yukon North Slope is unknown. However, in a relatively untrapped region of Alaska’s north-western Arctic foothills, wolverine attained fall densities of 1.35-1.82/100 km2. A population study of the Yukon North Slope was conducted in 1993/94.
Preferred habitat for wolverine is poorly known. In northern Alaska, remnant snowdrifts in small drainages with meltwater caverns are believed to be important for maternal females and their offspring. Snowdrifts are thought to provide den sites. The quality of wolverine habitat is probably linked to the biomass of large mammals; as such, the seasonal occurrence or range of the Porcupine caribou herd may provide good wolverine habitat. Places where ground squirrels occur may be important too.
From 1988 to 1999 Inuvialuit harvest data was collected through the Inuvialuit Harvest Study. In the period from 1988 to 1997, the average annual harvest of wolverine reported by Aklavik residents was ten. The harvest during this time was biased toward males; the explanation for this is unknown. Most wolverine are tracked and shot in late winter, typically by caribou hunters. The Government of Yukon, in partnership with the Aklavik HTC, has been collecting furbearer harvest data from Inuvialuit residents of Aklavik since 2001. Harvest information recorded includes species, date, location, sex and maturity of the animal. Funding and support for the collection of harvest data is supplied through the IFA and other agencies.
Regulations under Yukon Wildlife Act, NWT Wildlife Act and National Parks Act apply in their respective jurisdictions.

Wolverine are occasionally seen in association with the Porcupine caribou herd. Because wolverine occur at low densities, the opportunity to see them is a particular attraction to Firth River rafters.
Populations would be threatened by excessive harvest pressure. Climate change is also thought to be a serious threat because wolverine denning habitat relies on snow drifts and the characteristics of this snow (and availability of it) are changing as a result of global warming.
There is an ongoing program to record species observed on Herschel Island. There are no other ongoing programs on the Yukon North Slope. The GNWT initiated a wolverine harvest monitoring and population health study in 2004. Aklavik trappers are participating in this study.
The field work for a population study of wolverine was completed in 1994. Radio transmitters were used to determine population size, composition, and distribution. Various research projects have collected carcasses for examination.

To meet conservation goals of the IFA, the co-management bodies are mandated to determine and recommend (to Yukon Government, GNWT and Parks Canada) a total allowable harvest and/ or promote research, if and when required.
The North Yukon Fish and Wildlife Management Plan includes a chapter on the management of furbearers in the Vuntut Gwitchin Traditional Territory which lies to the south of the Inuvialuit Settlement region in the Yukon. http://www.yfwmb.yk.ca/comanagement/
In 2003, the Wildlife Management Advisory Council (North Slope) and the Aklavik Hunters and Trappers Committee undertook a project to record traditional knowledge of certain birds and animals on the Yukon North Slope. The observations, comments and concerns expressed by Aklavik residents as part of this study were as follows:
Community-based information on this species may also be found in the reports of the annual community-based monitoring program conducted in Aklavik and neighbouring communities by the Arctic Borderlands Ecological Knowledge Co-op. http://www.taiga.net/coop/community/index.html
