Five caribou that were raised in captivity have been set free to roam alongside wild caribou in Jasper National Park’s Tonquin Valley. These animals were raised at North America’s first caribou conservation breeding center, managed by Parks Canada to help increase the caribou population in the region.

Parks Canada has been actively involved in capturing wild caribou over the past two years and relocating them to a breeding facility located 35 kilometers south of Jasper townsite. In June, the federal agency announced the release of the first caribou, consisting of four male yearlings born in captivity and one adult male from the Brazeau herd brought in for breeding purposes.

Jean-Francois Bisaillon, the program manager for the Caribou Recovery Program, described the emotional experience for the staff witnessing the caribou stepping into the backcountry on June 24 as a significant success for the caribou population.

Caribou have been designated as a species at risk in Canada for more than two decades due to habitat fragmentation and increased wolf predation resulting from industrial activities. The Parks Canada initiative was established over ten years ago to prevent the local extinction of caribou in the Rocky Mountains.

Currently, there are only 50 wild caribou, with 11 reproducing females remaining in the Jasper-Banff local population unit, covering the area south of Highway 16 in Jasper National Park and all of Banff National Park. Bisaillon highlighted the critical nature of the project, stating that herds with fewer than 10 reproducing females are not self-sustaining, emphasizing the importance of the ongoing conservation efforts.

In preparation for the recent release, Parks Canada captured ten wild caribou, including seven pregnant females, in Jasper National Park in March 2025 and brought them to the breeding center. Subsequently, seven healthy calves were born, and one orphan caribou was introduced from British Columbia. In March 2026, an additional six wild caribou were captured and added to the breeding herd.

The release of the five male caribou marked a significant milestone as they transitioned from the breeding center to the wild habitat of Jasper National Park. Transported by helicopter to a soft-release pen near Amethyst Lake on June 10, the caribou adapted to their natural environment and were observed moving freely within a short period.

The timing of the release was strategically planned to align with the movement patterns of the local wild caribou, leading to a seamless integration of the captive and wild herds. Bisaillon expressed satisfaction with the successful release, emphasizing the social nature of caribou and the positive reception by the wild animals.

As the female calves born in captivity remain at the breeding center to contribute to the population growth, the primary goal of the program is to restore the Tonquin herd to 200 individuals within the next decade before considering the reintroduction of the Brazeau and Maligne herds.

Ecologist Mark Boyce from the University of Alberta pointed out the connection between caribou decline in Alberta and the disruptions caused by forestry and oil industries to the ecosystem. The presence of increased prey animals, such as deer, elk, and moose, attracts more wolves, which further exacerbates the threat to caribou populations.

Despite protection from forestry and oil development, wolf populations pose a significant challenge to caribou survival in Jasper National Park, with the aftermath of the 2024 wildfire potentially intensifying this issue by promoting habitat changes favorable to prey animals.

Bisaillon emphasized the goal of achieving a balanced ecosystem without human interference to ensure the long-term sustainability and well-being of caribou populations in the region.
