Bison and the power of partnerships
Protecting bison cannot be done alone.
Parks Canada works in partnership with many Indigenous communities to help bison grow and thrive. Bringing the bison back can rekindle the longstanding relationship between Indigenous peoples and bison. Learn how Parks Canada’s bison transfers have been key to this process.
Bison are North America’s largest land mammal. Before European colonization, tens of millions of bison roamed many parts of the continent. By the late 1800s, their population was reduced to near extinction from overhunting and industrial demand. Only around 1000 bison remained.
Bison and the land
Bison play an important role in shaping landscapes as ‘ecosystem engineers’. Bison behaviours create conditions and habitats that can benefit many other plants and animals.
Bison waste incubates insect eggs and larvae. Many endangered prairie bird species eat insects. They benefit from the bison’s influence on insect presence. Endangered prairie birds also benefit from bison’s grazing patterns. Bison are helping Parks Canada manage the habitat of at-risk prairie bird species and their recovery.
Bison create “wallows” when they roll in the dirt to take dust baths. Wallows can fill with water when it rains, and provide important habitat for many prairie wildlife. Bison also spread seeds around as they travel. Birds use their fallen fur for nesting.
Parks Canada conserves the only two subspecies of bison in North America: Plains Bison and Wood Bison.
Plains Bison have a:
- large, bushy hairstyle on their head
- rounder back hump that sits directly over their front legs
- historic range as far south as Mexico, as far east as Florida, but were most common on the Great Plains
Wood Bison have:
- bigger and taller bodies
- smaller, pointier beards, darker fur, and hair that droops over their forehead
- a tall and triangular hump that sits far ahead of their shoulders
- adapted to colder climates, including northern Alberta, Alaska, the Northwest Territories, and Yukon
Bison are important for the health of natural ecosystems in which they normally occur. They also support many Indigenous cultural connections to the land and their ways of knowing.
Cultural connections with bison
Bison have always been important in the lives of many Indigenous peoples in what are now the Prairie Provinces, British Columbia, Northwest Territories, and other parts of Turtle Island. Many Indigenous communities have long held deeply cultural and spiritual connections with bison. They have relied on bison for:
- social and ceremonial purposes
Many Indigenous cultures continue to hold close relationships with their relatives—the bison. This includes for spirituality, food sovereignty, and social-economic development.
Parks Canada and bison
For over one hundred years, Canadian national parks have worked to maintain and restore bison herds for conservation. Parks Canada also works to uphold bison health and genetic diversity by maintaining disease-free conservation herds.
Parks Canada wildlife scientists are working with partners to restore healthy bison populations. Among other efforts, they are developing tests for detecting bovine tuberculosis (TB) and brucellosis. Early detection will help reduce transmission of these diseases. They are also working to develop a vaccine that will protect bison from getting bovine TB. Watch the video below from Wood Buffalo National Park to learn more.

Parks Canada employees conduct a series of tests on the bison and take its temperature.
[Todd] “87? Nice… that’s decent.”
Parks Canada employees place a red blindfold over the bison’s face.
[Todd] “Put a blindfold on him to reduce any visual stimulation. We’re going to hook him up on oxygen, then we’ll start taking our samples.”
Parks Canada employees hook the bison up to an oxygen machine, placing two clear tubes into the bison’s snout.
[Text] In the past, bison had to be captured multiple times or even killed to test for bovine diseases, which made detection difficult.
[Text] These new blood tests will be able to detect bovine tuberculosis with a single blood sample.
Parks Canada employees collect blood from the bison using clear syringes. Employees are wearing toques and parkas to protect them from the cold and snow.
[Todd] “So the whole reason we’re trying to get blood out of these animals—and we have to keep the blood at room temperature, which is extraordinarily challenging in the winter, when we prefer to capture them—is so that we can run what’s called an interferon gamma release assay and find out if these bison have been exposed to tuberculosis.”
Parks Canada staff, wearing plastic gloves, deposit blood samples into test tubes at a chemistry lab in Fort Chipewyan.
[Todd] “It’s a blood test, and we can run part of it back at the lab, back at Fort Chipewyan, and then the rest of that test is done back at VIDO-Intervac in Saskatoon. That’ll tell us whether this animal’s actually been exposed to tuberculosis.”
A beige GPS collar lays on the ground in the snow next to the bison. Parks Canada employees place the collar around the bison’s neck.
[Todd] “This is a GPS collar that communicates with satellites, gives us a position roughly every two hours. And we’re hoping they’re going to stay on for at least a year, but we will see. Wow, he’s like right out … but still breathing well.”
Parks Canada staff continue to take measurements, hair samples and other biological samples from the bison.
[Todd] “We’re going to collect hair samples from this bison for genetic analysis, but also for looking at heavy metals and contaminants, and we’re going to collect a fecal sample as well. This is the glamorous part of the job, eh, Rob?”
Bison wakes up and begins to stand. The helicopter takes off and flies over the bison, who has rejoined the herd and is running through the snow.
Todd is standing in the small chemistry lab at Fort Chipewyan. He shows viewers the lab equipment that will be used to process the biological samples.
[Todd] “So we’re back from the field now, and it’s time to process the samples that we’ve collected from the bison. We’ve got our hair samples, right here, going to use that for genetic DNA analysis, something we can archive for a long time. And we’ve got our fecal samples, and our blood samples.”
Todd shows the camera the test tubes containing the biological samples.
[Todd] “We’ve got two green-topped tubes, two serum tubes, and a RNA tube for doing some transcriptomic work.”
Todd handles the samples by inserting his hands into gloves inside a small sterile tent. The sterile tent allows him to handle the samples without contaminating them.
A scientist inserts the samples into a small incubator that sits on top of a desk in the lab.
[Todd] “We’re now going to incubate the blood overnight to produce what’s called interferon gamma. And that’s a kind of protein that’s released from cells, and if the bison have been exposed to bovine tuberculosis in the past, they’ll have higher amounts of interferon gamma in the cell the next day. And that’s going to basically tell us if those bison have been exposed to bovine tuberculosis.”
Todd prepares his test tubes with the blood samples, using gloved hands inside the sterile tent.
[Todd] “So now we’re going to drop some of this blood from these animals that we collected today. In the future, we’re also hoping to develop some sophisticated vaccines, for both bovine tuberculosis and brucellosis.”
Todd speaks to the camera standing outside the lab in Fort Chipewyan.
[Todd] “Well, we’re all wrapped up here in Fort Chipewyan, we’ve had a pretty successful trip, we captured about 18 bull wood bison over the past 10 days or so. We’re heading back, we’re going to process the blood samples we’ve collected at VIDO-Intervac, and find out how many of those animals were actually exposed to bovine TB. Overall it went really well, so we’re really happy with the way things went.”

Approximately 70% of the bison bulls tested in Fort Chipewyan were positive for bovine tuberculosis.
Work to reduce these numbers will continue for years to come, through the collaboration of Parks Canada, industry, academia, and the Bison Integrated Genomic (BIG) project at Genome Canada.

Establishing bison herds would not have been possible without the stewardship of bison by Indigenous peoples. In the late 1800s, two Indigenous ranchers managed the Pablo-Allard herd. These animals were among the last wild Plains Bison. The Government of Canada bought 700 of their bison in the early 1900s. The bison were sent to Buffalo National Park and Elk Island National Park. Lessons were learned from the operation of Buffalo National Park. The bison at Elk Island have since become the main source of bison stock for reintroduction projects.
Today, Parks Canada manages bison across the country. These sites include:
- Elk Island National Park
- Grasslands National Park
- Prince Albert National Park
- Banff National Park
- Waterton Lakes National Park
- Riding Mountain National Park
- Rocky Mountain House National Historic Site
Wood Buffalo National Park was established to protect the last remaining population of wild Wood Bison in North America.
Bison transfers at Parks Canada
Parks Canada is helping to restore bison back onto the land through the transfer of bison. Bison transfers help to increase the number of conservation herds in Canada and beyond.
The Agency has transferred over 3400 Plains and Wood Bison to conservation sites and other interested groups. Over 600 of these bison were transferred to Indigenous communities to support them in establishing their own conservation or cultural herds.
Watch the types of bison that Parks Canada has transferred, and who has received them:
Parks Canada has made significant contributions to bison conservation and restoration in North America. Today, many bison herds exist across the landscape thanks to these transfers.
The historic return of bison
Bison had been absent from Grasslands National Park in Saskatchewan for over 120 years. Parks Canada reintroduced Plains Bison back onto the landscape as a large grazing herbivore in 2005.
Bison provide visitors with a greater diversity of native plants and animals to see when visiting the park’s West Block. Watch the story of the bison return to Grasslands National Park.
Return of bison to Grasslands National Park
0:00 Bison went nearly extinct at the end of the 19th century.
0:06 Thankfully, they returned to Grasslands National Park in 2005.
0:12 The initial herd arrived from Elk Island National Park and consisted of 71 bison.
0:17 The herd’s reproduction rate is excellent.
0:21 The herd size is now kept between 300 and 500 bison.
0:27 Parks Canada researchers collect different samples from the bison.
0:33 These samples help scientists monitor the health of these animals.
0:38 This data is also helps maintain a herd structure similar to what would have been found in the wild.
0:46 Bison are recognized as ecological engineers.
0:56 Grazing is essential to the health of the mixed-grass prairie ecosystem.
1:01 Many species at risk benefit from the presence of the bison.
1:11 Thumbs up for the bison!
1:19 Like. Comment. Share.
Plains Bison were also reintroduced to Banff National Park in 2017 from stock in Elk Island. Watch the historic return of bison to Canada’s first national park.
Wild Bison Return to Banff National Park
0:10 My name is Karsten Heuer and I am the bison reintroduction project manager for Banff National Park.
0:18 My job is to orchestrate all the moving parts of trying to get bison from Elk Island National Park into Banff National Park.
0:28 Parks Canada's primary mandate is to ensure what we call ecological integrity, which means the health of the ecosystem.
0:35 And because something has been missing, North America's largest land mammal, part of our job is to try to bring it back.
0:42 And that’s what this is all about. It's about that effort.
0:47 From about noon today until about hopefully about noon tomorrow, so a 24 hour period
0:52 we are actually going to be doing an operation that has a lot different moving parts.
0:57 The first part is bringing the animals through the Elk Island corral system and chute system,
1:03 give them a tranquilizer, and then do some last minute changes to ear tagging.
1:08 And then we will start to load them in groups of three and four through the chute system
1:12 up the loading ramp, into the containers that we've modified.
1:16 They're basically seacans or shipping containers with ventilation in them and a few additions to the doors.
1:22 And then, we'll truck them for 400 km. That will then take us to the end of the gravel road, Ya Ha Tinda Ranch.
1:30 And then we will actually bring in a helicopter in tomorrow, a heavy lift helicopter
1:33 that's coming from the coast and that will pluck each individual crate off the flat-bed trucks.
1:39 One by one, over the ridge, about 20 km into the heart of the reintroduction zone
1:44 where we have a pasture fenced,
1:47 where we are going to hold them for the next 16 months, feed them, support them,
1:52 allow them to calve safely twice, and then do the release after they have anchored to that landscape.
1:58 and have adopted it as their new home.
2:13 There's been so much research, there's been so much consultation, like literally years.
2:18 We've got everything in place that we could have possibly thought of.
2:22 And really, from here on in, it's going to be up to the animals.
2:34 You know, we are talking about giving a species a second chance.
2:38 The seed that we are planting today, you can't almost imagine what it might lead to in 50 or 100 years.
Bringing bison back onto the land creates new opportunities for everyone to learn about the importance of these animals.
Managing bison at Parks Canada
There are no natural predators to keep the bison herds within the carrying capacity of some national parks. Staff from Elk Island and Grasslands National Parks must remove bison to prevent overpopulation. This would lead to overgrazing, which negatively impacts bison and other wildlife in the parks. The need to remove animals creates opportunities to transfer bison to other groups across North America.
The aim of managing and transferring bison at Parks Canada is to help the overall numbers of Plains and Wood Bison in North America. Parks Canada transfers bison to groups that want to start or supplement their own conservation herd.
Park staff manage bison following international guidelines for bison conservation herds. Actions taking place in key locations include:
- regularly monitor bison population size, sex, age structure to inform herd management
- perform herd health checks throughout the year, including disease testing to help maintain the herd health, where applicable
- collaborate with researchers on genetic testing to ensure their bison have a healthy and diverse gene pool at Grasslands National Park
Staff at Grasslands and Elk Island National Parks must gather bison for transfers when the populations are becoming too large. During this time, they also perform bison health checks. Staff reward bison with desirable food items near the handling facilities. The bison learn when and where these food items become available. This means bison arrive at the handling facilities when their presence is desired. In this way, difficult round-ups are avoided.
Bison and a path towards reconciliation
Parks Canada is learning and understanding more about its role in the path to reconciliation through the bison program. We have supported several Indigenous communities in re-establishing bison onto lands they manage.
These transfers help Indigenous peoples strengthen their cultural and historic connections with bison. They also support Indigenous-led social and economic opportunities around bison. Wanuskewin Heritage Park was one recipient of bison transfers. Darlene Brander, Chief Executive Officer with Wanuskewin Heritage Park says, “when the bison come back, the culture comes back.” Watch the video below to learn more about the bison transfer to Wanuskewin Heritage Park.
The Return of the Bison to Wanuskewin Heritage Park
0:06 There’s no place on earth like Wanuskewin Heritage Park.
0:14 What we’re hoping that the visitors will take away is the power of partnership.
0:19 We’ve had this wonderful partnership with Parks Canada
0:22 where we’re able to bring the bison back which strengthens our culture.
0:25 When visitors come here they get to see Indigenous culture in action,
0:29 they get to participate in curriculum programs around the bison,
0:34 and have an authentic experience that makes them better human beings.
0:42 The bison were there for our sustenance.
0:44 They, historically, provided everything we needed.
0:50 The bison are the iconic animals of North America.
0:54 They had a near demise, extinction,
0:57 very close to extinction in the early 1870s,
1:01 and by 1885 their population had gone from 26 or 30 million
1:07 down to less than a thousand.
1:09 So, that’s cataclysmic.
1:18 We move about 200 animals,
1:19 our goal is to keep the capacity of our herd between 300 and 500,
1:24 400 to 500 is optimal.
1:26 So, we send those animals on an order of preference
1:29 to other conservation herds, to Indigenous groups,
1:32 to educational institutions, and if we still have animals left over after that
1:36 they go to public auction.
1:43 But there are some practical implications here too.
1:46 When you go from 26 to 30 million
1:49 down to a thousand,
1:50 and then you start increasing the size of these herds,
1:53 because of restoration efforts,
1:55 there is what is known as a genetic bottleneck.
2:03 Being able to increase genetic diversity means sharing animals.
2:08 Like the arrangement we have with Grasslands
2:11 is one way of doing this.
2:13 I love the idea that Wanuskewin
2:16 would be a beacon,
2:18 a model for grassland restoration,
2:22 bison restoration, and to celebrate First Nation cultural history.
2:27 It’s a realization of the dream of elders from 40 years ago,
2:30 and we’re so happy to have that realization back.
2:33 There was a prophecy that had once said that
2:36 when the bison come back, the culture comes back.
2:54 I think that’s how
2:57 people can work together.
2:58 That’s an example that we have to take care of each other,
3:02 when things are down…
3:05 And then a better life.
The continued conservation of bison
Over a century of hard work and partnerships has helped bison regain their place on the landscape and within cultures. Yet, the work to conserve bison is not over. Bison transfers remain an important step in bison conservation.
Parks Canada continues to learn from past experience with bison transfers. We adapt protocols and handling facilities to better manage conservation herds. We continue to work with partners to restore bison back onto the land.
Parks Canada is honoured to support the restoration of cultural heritage of Indigenous peoples through bison transfers. Parks Canada will continue to work in partnerships toward the survival and wellbeing of this iconic animal.
