Controversial choice: To cull or not to cull wolf populations in the Northwest Territories

A one-year pilot project is underway in an effort to protect threatened caribou populations in the territory, but some conservation groups say wolf culls miss the bigger picture

The Northwest Territories government plans to remove up to 80 per cent of its wolf population with a 20-day aerial cull — a controversial move that echoes a similar program adopted by British Columbia in 2015. 

The plan is part of an attempt to save threatened caribou herds in the Bathurst and Bluenose-East regions. One wolf can eat up to 29 caribou a year.

The territorial government worked with the T???ch? Government to finalize the plan through a series of community meetings and planning committees, although the Wek’èezhì? Renewable Resources Board (WRRB) — a co-management authority established by the T???ch? agreement — was unhappy about the delays in achieving final approvals.

“The decision made it clear that the governments’ delay in preparing and submitting the proposal would effectively mean that no relief by way of predator control could be provided to the k?k’èet??and sahtì ekw?? herds in the 2020 harvest season,” says Joseph Judas, WRRB chair. 

Judas also calls it an “unfortunate outcome” for the caribou herds, adding that they’re in a “precarious position.”

The WRRB says they were left choosing between two bad options, but the timing of the proposals left them no choice. They were hoping that traditional ground harvesting of the wolves would cull enough, but quotas weren’t reached. 

Liz White, director of the Animal Alliance of Canada, says governments making these decisions are failing to recognize the human impacts behind the precipitous decline in caribou numbers across Canada.

“They are ignoring the impact of industrial development, forestry, the various man-made impacts on the caribou habitat,” says White. “It demonizes the wolf for something largely caused by people.”

According to White, more than 25 advanced mining projects intersect with caribou ranges in the Northwest Territories and into Nunavut. These mining projects encroach onto calving grounds for the caribou. Noise levels cause stress to the animals, and the loss of their habitat is resulting in increased predation of calves.

“They have to come to terms with the impact of the development that they are allowing in that area,” says White. “I don’t think you can have both.”

White says there’s no immediate solution to protect caribou without killing wolves, but that the current approach will result in a loss to both caribou and wolf species. 

In British Columbia, the controversial practice of radio collaring and aerial culling of wolves has been underway since 2015. Pacific Wild, a wildlife protection non-profit, estimates more than 400 wolves have been killed in the last four years by this method and agree that a wolf cull is not a sustainable way to help caribou populations recover.

“Instead of dealing with the root of the problem, such as protecting caribou habitat, banning harmful industry — including mining, logging operations and some backcountry outdoor activities — in critical caribou habitat, the government is taking an easy way out,” says Rebeka Breder, a lawyer for Pacific Wild.

However, B.C. government officials say the five years of aerial culls have been successful, turning a 15 per cent per year decline of the caribou in that province into a 15 per cent per year increase. Government biologist Michael Bridger told CBC aerial culls “buy time.”

“The wolves do recover at a very high rate annually, anywhere from 60 to 80 per cent in a given year,” he said. “So it is a method — this aerial wolf reduction — that has to be sustained over time in order to achieve those results in the caribou population.”

Wolf culls in Canada have taken different forms since the 1900s, including poisoning, trapping and ground shooting. There are some data sets that show these culls have little impact on protecting the caribou population.

The one-year pilot in the Northwest Territories will lead to a five-year plan, which is set to be reviewed again in August 2020.
