Bison Return to Canada’s Oldest National Park After 130 Years
A herd of 16 plains bison were reintroduced to Canada’s oldest National Park last week.
It’s been more than 130 years since a bison was spotted in Banff—well before the park was officially established in 1885. By bringing back the “grazers,” park officials hope they will be able to bring a better balance to the park’s ecosystem.
For 18 months, the small herd of bison will be kept in a pasture within the 740-square-mile “reintroduction zone” on the eastern slopes of Banff National Park. After that time, park rangers will open pasture gates and the bison will be permitted to roam about the entire area.
“This would be one of only four plains bison herds in North America that would be fully interacting with their predators and shaping the ecosystem as they did over a hundred years ago,” Karsten Heuer, the bison reintroduction project manager, told The Guardian.
The bison come from Elk Island National Park and were fully screened for diseases before transfer. The herd includes 10 pregnant females and six young bulls.
The relocation process put the 16 animals in five large shipping containers and drove them 250 miles (via truck) across Alberta to Banff. For the last 25 miles of the journey, the shipping containers full of bison were attached to helicopters with a long cable and flown in. To prevent the animals from hurting each other in transit, workers put rubber hoses on each animal’s horns.
This is a historic moment and a perfect way to mark Canada’s 150,” Catherine McKenna, the country’s minister of environment and climate change, said in a statement. “Not only are bison a keystone species and an icon of Canada’s history, they are an integral part of the lives of indigenous peoples.”
