Caribou (Rangifer tarandus caribou) are members of the deer family. They are larger than a deer but smaller than an elk. Caribou have the biggest antlers and hooves in the deer family relative to their body size. Both male and female caribou can grow and shed antlers each year, though at different times. Their large hooves act like snowshoes, helping them travel in deep snow, dig for food, and even paddle while swimming.
Mountain caribou in Jasper are usually found in small groups. During long, cold winters they survive by digging through the snow to eat lichens. In June, females isolate themselves in more remote areas to give birth to a calf. This protects their young calves from predators like wolves, grizzly bears and cougars.
Caribou that live in Jasper National Park are part of a subgroup of woodland caribou herds called southern mountain caribou. Many southern mountain caribou herds are small and endangered and some are gone forever. There are four caribou populations with habitat in Jasper National Park: À la Pêche, Brazeau, Maligne and Tonquin. There has been no sign of the last members of the Maligne herd since 2018.
Where they live
Southern mountain caribou herds are found in the mountain regions of Western Canada. Their habitat includes parts of Banff, Jasper, Mount Revelstoke and Glacier national parks. Mountain caribou live in old-growth forests and high alpine areas to avoid predators. They move between alpine areas in summer and subalpine forests in winter.
In Jasper National Park, caribou can be found in small but stable numbers in the Tonquin Valley and the Brazeau mountain ranges near the Icefields Parkway, and in larger numbers on either side of Jasper National Park’s northern boundary.
Why they are at risk
Mountain caribou are well adapted to living in harsh environments to avoid predators. However, because of their low reproductive rate and need for large areas of uninterrupted habitat, caribou populations grow slowly and can decline quickly. The most significant threat to caribou in the southern areas of Jasper National Park is their small population size.
There are not enough reproductive females in the Tonquin and Brazeau caribou ranges for the populations to recover on their own.Frankie Thunderbowl: the Mystery of the Missing Caribou (Explore by the Seat of your Pants)
The Tonquin herd is estimated to have 49 to 55 caribou and the Brazeau herd to have fewer than 10 caribou. These two herds have had low, but stable numbers since 2015.
The number of breeding female caribou is now so small – an estimated 9 to 11 in the Tonquin and less than 3 in the Brazeau – that these herds will not produce enough calves each year to grow the herds.
Small herds are especially vulnerable to predators, disease and accidents like avalanches. The Tonquin and Brazeau caribou herds in Jasper have become too small to recover on their own and their future is precarious.
Mountain caribou populations have declined over the last century primarily because of changes to the number and distribution of other prey like elk, deer and moose and predators like wolves.
Changes to predator and prey relationships are often caused by human activities that disturb or change a landscape, such as industrial development. Human activities on neighbouring lands can also have cascading effects on predator-prey dynamics within protected areas like national parks.
In Jasper, the primary cause for altered predator and prey populations is historical. Wildlife management practices introduced by the government in the early 1900s led to an overabundance of both elk and wolves in Jasper National Park for decades. This had long-term effects on caribou.
People can displace caribou from areas that are safe or that have good food sources. Caribou in the park can be disturbed by trail users, dogs, aircraft, or be killed in vehicle collisions on roadways.
Caribou have evolved to survive in the deep snow that drives predators to lower elevations where prey are easier to find and hunt. Trails packed by skiers and snowshoers can help lead wolves into these otherwise inaccessible areas.
Caribou rely on old-growth forests as their primary winter habitat. Mature forests are becoming more vulnerable to insect outbreaks and wildfires as a result of climate change and historical practices of putting out all wildfires. The younger forests that emerge after these disturbances favour deer, elk and moose, which support increased predator populations. The result is increased chances that caribou will encounter predators.
How we are helping
Since 2006, Parks Canada has taken steps to reduce threats to caribou and create better conditions for caribou survival and recovery.
Read more about Parks Canada’s caribou recovery plans here.
Parks Canada has a plan to rebuild the Tonquin herd, and eventually the Brazeau and Maligne herds, by adding animals to the population through conservation breeding.
Conservation breeding programs are used to prevent animal species from becoming extinct and to help in their recovery. This involves capturing a small number of wild animals, breeding them in captivity, and releasing their offspring back into the wild to increase populations of endangered wildlife.
Over the next several years, Parks Canada will build a caribou conservation breeding centre in Jasper National Park.
Parks Canada has implemented wildlife management practices to lessen human influence on wolf and elk populations.
This included moving elk away from the town where they take refuge from predators. We also began incinerating roadkill rather than discarding it into gravel pits where wolves could access it and supplement their diet.
Elk and wolf populations are now at levels that would no longer be a threat to healthy, self-sustaining caribou herds.
To avoid disturbing caribou, dogs, bicycles, and landing and takeoff by hang gliders and paragliders are not allowed in caribou habitat.
In spring, speed limits on highways are reduced to 70km/h in areas where caribou may cross the road.
Helicopters, airplanes, and drones must follow guidelines that keep them away from wildlife. Recreational use of drones in Jasper National Park is prohibited.
From November 1 to May 15, access to occupied caribou ranges is closed. We also no longer set cross-country ski tracks or permit the use of snowmobiles (for park or outfitter operations) in caribou habitat.
This prevents people from creating packed trails that could help wolves travel into important winter caribou habitat.
In Jasper National Park, critical habitat for caribou is protected by law under Canada’s Species at Risk Act. The national park provides a large protected area of secure habitat for caribou, where disturbance and habitat fragmentation are minimized.
We assess projects in the park, including prescribed fire, for their impact on caribou and their habitat.
In 2015, Marmot Basin Ski Area’s leasehold was reduced by 17%, creating 118 hectares of wilderness habitat to benefit caribou and other wildlife. Ski lift development in off-piste ski runs is also prohibited.
Parks Canada has an ongoing caribou monitoring program that collects information about caribou, deer, elk and wolves in a variety of ways including aerial surveys, remote cameras, radio collars and scat DNA analysis.
This information helps us understand the relationships between these animals, how they use habitat in the park, and trends in their populations over time.
Parks Canada and the province of Alberta collaborate on monitoring the À la Pêche population. Jasper National Park also collaborates with the Canadian Wildlife Service, Natural Resources Canada, the province of British Columbia and universities in Canada and the United States on research projects to support caribou recovery.
How you can help
When planning a trip, research closure areas and dog restrictions in caribou habitat. If you get the opportunity to see a caribou, give them space. Do what you can to limit climate change and support initiatives that protect old-growth forests.
To report caribou sightings or people bringing dogs into restricted caribou habitat, please observe, record and report this information to Parks Canada Dispatch at 780-852-6155. Visit our web page with essential information for residents and businesses.
