B.C. predator cull would target 80 per cent of wolves in caribou recovery areas

The provincial government is proposing a predator cull that would kill more than 80 per cent of the wolf population in parts of central British Columbia that are home to threatened caribou herds, according to correspondence from the Ministry of Fores

A five-year program of wolf reduction has turned a 15 per cent a year decline in the population of the Central Group of the Southern Mountain Caribou into a 15 per cent a year increase, according a memo from the B.C. Caribou Recovery Program.

The provincial government is proposing a predator cull that would kill more than 80 per cent of the wolf population in parts of central British Columbia that are home to threatened caribou herds, according to correspondence from the Ministry of Forests, Lands, Natural Resource Operations and Rural Development.

"The objective of this wolf reduction program is to reverse caribou population decline in the Tweedsmuir-Entiako, Hart Ranges, and Itcha-Ilgachuz herds," says a memo signed by Darcy Peel, director of the B.C. Caribou Recovery Program. "To reverse caribou population declines, high rates of wolf removal (>80%) must be achieved."

The Tweedsmuir-Entiako and Itcha-Ilgachuz herds are in the central part of the province, roughly east of Bella Coola and west of Quesnel, while the Hart Ranges herd is near the Alberta border, east of Prince George.

A parallel cull is also proposed for the Itcha-Ilgachuz herd area to "remove cougars that have likely begun to focus on caribou as a prey source."

A 30-day consultation with Indigenous communities and "targeted stakeholders" is underway.

A five-year program of wolf reduction has turned a 15 per cent a year decline in the population of the Central Group of the Southern Mountain Caribou into a 15 per cent a year increase, Peel writes.

A study of 18 caribou herds released earlier this year found that populations stabilized or increased in eight of 12 herds in areas where wolves were culled. Six herds that were not subject to predator removal continued to decline, according to the study led by Robert Serrouya, director of the Alberta Biodiversity Monitoring Institute's Caribou Monitoring Unit.

The Central Group's Klinse-Za herd posted the most dramatic recovery through a combination of predator reductions and maternal penning, in which pregnant caribou and calves are protected by fencing.

Serrouya found that predator management must be applied "intensively" to produce a positive result and that combining strategies such as culls, restoration and safe havens enhanced the effectiveness of recovery efforts.

Serrouya's study identifies predators as a "proximate" cause of caribou decline, while ecosystem alteration is the "ultimate factor."

"Habitat restoration is the long-term piece to this strategy," Serrouya said in a interview. "But if we wait for the habitat to be restored and do nothing else, there won't be any caribou to occupy it."

Several herds in B.C. have already turned around because of this multi-pronged approach, he said.

B.C. is currently rolling out a $47-million caribou recovery plan.

"Wolf populations in these herds are far above the level that research tells us is needed to ensure caribou recovery," the ministry wrote in response to questions from Postmedia. "These herds have reached a critical point, with a combined total of only 801 individual animals. All have had steep declines in recent years due to predation."

The proposed cull was condemned as outdated thinking that ignores the real cause of the caribou decline by a one-time NDP candidate and former conservation officer.

Habitat loss to logging, mining, oil and gas development and roadbuilding is the real problem, said Bryce Casavant, now a conservation policy analyst with Pacific Wild.

"It's not a scientific discovery to say that if we kill the predators, the caribou will do a little better," he said. "What's really happening is that taxpayers are subsidizing inappropriate industrial operations by paying for the cull and the wolves are paying with their lives."

The ministry memo advocates an adaptive management approach to conservation, combining predator management with other strategies and studying their effectiveness as they are applied.

Casavant argued that so-called "science on the go" is intended to support the government's predator management strategy.

"The data shows that habitat loss is the largest agent of decline, not wolves," he said.
