The Alberta government is planning to sell off crucial caribou habitat to the energy industry just days after a federal scientific panel said the herds were in immediate danger of vanishing completely.
Starting Wednesday, Alberta Energy is to auction off 1,700 hectares of land north of Grande Cache — home to the remaining members of several herds of mountain caribou.
A federal scientific panel ruled earlier this month that those herds should be assessed as endangered, the highest level of threat available under Canadian law, because their numbers have tumbled by about 60 per cent over the last decade.
“Most of it’s industrial disturbance,” said Justina Ray, one of the biologists who completed the assessment for Environment Canada’s Committee on the Status of Endangered Wildlife in Canada.
“There’s also pressure from recreational activities as well — everything from snowmobiles to helicopter skiing. The (factor) that has caused the greatest change is industrial disturbance.”
The Alberta government did not respond to requests for comment.
About 1,200 hectares on the block is on the range of the 78-animal Narraway herd. Data compiled by Global Forest Watch suggests more than 81 per cent of that range is already disrupted. The other 500 hectares are from the 100-member Redrock-Prairie Creek herd’s range, about half of which has seen human impact.
The most recent figures for those areas are four years old.
Ray said the herds suffer as development cuts holes in old-growth forest.
The plants that grow back are much better habitat for deer and moose. Those animals are the main prey of wolves and, once the wolves gain access to an area, they start to eat caribou as well.
Alberta conducts a vigorous wolf-kill program. But provincial officials have acknowledged that culling predators won’t protect caribou herds forever.
Saving mountain caribou herds is important for the overall genetic diversity of caribou in both British Columbia and Alberta, Ray said. She added that policy-makers need to consider that habitat pressures centred in Alberta are starting to spread.
“We’re noticing a creep northward of these pressures and the impacts as a result,” she said. “It’s a question of where to draw the line.”
Carolyn Campbell of the Alberta Wilderness Association pointed out that the federal and Alberta governments have a recovery strategy for boreal caribou that commits to restoring their range so at least 65 per cent of it is useable. A strategy for mountain caribou is in the works, but nothing has been completed.
Provincial guidelines on how energy companies should operate on caribou ranges don’t go far enough, Campbell said. They don’t set disturbance limits and mostly deal with timing.
“It’s just going through the motions, to say there are restrictions on caribou range,” said Campbell.
The only thing that will preserve Alberta’s caribou herds is governments being willing to say no.
“Given the difficult state of these populations, it will require both intensive management and it will also require some restraint of our activities,” Campbell said.
“We can’t try and fix what’s happening with respect to their habitat without actually holding off with new disturbance.”
