In Decline, Caribou Face a Tough Winter in Canada

It was once our largest caribou herd, and one of the biggest herds of large migratory mammals anywhere in the world.  The George River caribou of northern Quebec and Labrador were surpassed in numbers perhaps only by Africa’s wildebeest. But now their population is perilously small—about 4 percent of its peak. Although migratory caribou, also called reindeer, are known for wide swings in population size, encroachment of industrial development into their habitat puts these animals at increasing risk.

In the late 1940s, the George River caribou herd may have declined to as few as 3,500 animals, and in 1958, a careful census estimated its numbers at 15,000. Historically, when the herd reached these low points, many of the Innu, Cree, and Inuit people, who lived in what is now northern Quebec and Labrador, died from starvation. But the George River caribou herd rebounded with amazing vitality, reaching an astonishing 775,000 animals by 1993, ranging over an area larger than France.

Today it is one of a handful of large terrestrial mammal populations around the world that continues the long-distance migration its ancestors carried out for millennia. In a single year, some of these animals will travel thousands of kilometers across Canada’s boreal forest between their wintering and calving grounds.

The current decline of the herd is due in part to overgrazing of its summer range, resulting in higher mortality from poor nutrition. By 2001, the herd was at 385,000 animals and continuing to decrease, totaling 75,000 animals in 2010. The most recent survey puts the herd size at fewer than 28,000.

This steep drop forces us to consider whether and how to address the low numbers. The populations tend to rebound after the number of animals foraging in certain areas decreases and the preferred foods grow back. But small numbers create a vulnerability to conditions that could push the population over the edge. As mining and other interests propose development of the same lands that the caribou use for calving and other phases of their life cycle, the animals have fewer places to go. These types of spatial limitations make them more vulnerable to predators. The incursions also make it harder to find areas that are good for foraging and free of mosquitoes and skin-burrowing warble flies that weaken calves and older animals. Add to that the challenges caused by climate change, and a herd at low population size could be at risk of endangerment.

There is some good news for the George River caribou herd, however. The government of Nunatsiavut in northern Labrador recently endorsed a proposal to put a 14,000-square-kilometer (3.5 million-acre) area of George River calving grounds off limits to mineral exploration and other industrial development. Additional sections of the herd’s calving grounds are already protected within the Torngat Mountains National Park and within the George River and Pyramid Mountains interim protected areas. In addition, the Inuit government territories of Nunavik and Nunatsiavut, where the calving grounds are located, are pressing for even more land protections.

The Innu of Quebec and Labrador have maintained an intimate relationship with the George River caribou for millennia. This summer, an Innu-led organization hosted a gathering of Innu leaders, scientists, and advocates working in partnership with the Pew Environment Group’s boreal protection efforts. They met in an ancient encampment along the George River known as Mushuau-Nipi to discuss ways to blend modern conservation and aboriginal knowledge to achieve healthy caribou populations.  Participants agreed that to ensure recovery of the herd, a 90,000-square-kilometer area in far northeastern Quebec and northwestern Labrador must be protected, including the Nunatsiavut government’s proposed no-development zone.

Let us hope that the leaders of the governments of Quebec and of Newfoundland and Labrador will follow suit and make this region a model of balance between ecological needs and industrial opportunities. The world will be watching to see whether the George River caribou can rebound and continue on their timeless treks across the wide-open spaces of Canada’s north.

    We were one of the first outfitters to hunt off the George River herd and we were also one of the last outfitters to hunt off the George River herd before it was officially closed to all sport hunting. During our last few years that we hunted off the George River herd every time a small herd of caribou came through it was followed by a pack of wolves. Some of our guides have witnessed on more than once occasion one or more wolves hunting down a healthy mature bull caribou. It is certain that the wolves will eat off the sick but they most certainly kill off any calves that they can get a hold of too and when none are available they will and can kill any caribou they decide to kill. To say that they strictly eat off the sick caribou is completely false. We have spent the last 40 years hunting and outfitting caribou in Nunavik (northern Quebec). Unless the wolves are controlled the caribou will not make a comeback. My opinion!! We did not use to see wolves and when we did we all talked about having seen one. That changed in the most recent years and now Labrador and northern Quebec is over run by wolves. We have a problem and it is called predation!

    having just read the book titled ‘never cry wolf ‘. I share that that in 1930 the caribou pop. was 4 million! trappers claimed that they only killed a few a year and it was wolves doing all the killing, but they lied and each killed 300-400 each to bait their traps and feed their dogs and there were 18,000 trappers! then the governments sponsored” tourism”, kill a magnificient caribou, helicopter or plane herding then slaughtering around 60 + just to get that special one allowed to be be headed for the game trophy. the wolves only ate the weak and sick and lived mainly on mice. before euro-pee-on s came the locals, wolves and caribou lived just fine. what’s this maylarkey in the article about over grazing? how can 28 K overgraze where 4 Millioin grazed only 80 yaers ago?

    Great idea, agree 100%.
    However, the Innu have not respected a complete no hunting ban of these animals imposed by the NL & Quebec governments. Both gov’t this year put a ban on all hunting of George river caribou. the Innu groups out of Natuashish & Sheshatshiu have both taken some of these protected animal this past winter to the tune of about 300-400 animals.. a bit hypocritical isn’t it ???….. they are all talk just to look good in the eyes of the world. however they do not really care what happens to these animals. if they wanted to help they should not be out hunting them when their numbers are so low and on the edge of extinction. than after the animals are wiped out they will blame the governments for not doing enough to help these animals. when it was really their fault…. no respect for anything!!!!

    protection of critical habitat is the right approach & regulated hunting when populations are under duress will make a huge impact. your work on caribou conservation is right.
