An unusual, costly, and labor-intensive experiment led by two First Nations aims to bring one of Canada’s many dwindling caribou herds back from the brink—and new research suggests it’s working.
In early March, Naomi Owens-Beek sat bundled against the cold, as her sled whizzed through the snow in the mountains of central British Columbia. In her hands, she clutched precious cargo: a sedated caribou—one of 114 of a herd facing extinction.
The lesson is that “it takes all the levers to recover caribou,” says Rob Serrouya, a caribou biologist with the Alberta Biodiversity Monitoring Institute. He has worked for years on caribou recovery in British Columbia but was not part of the Klinse-Za research.in North America: down. That extinction galvanized the West Moberly and Saulteau First Nations, says Owens-Beek, manager of treaty rights and environmental protection for the Saulteau First Nations. “We didn’t want to see a species die on our watch.”
To monitor the effects, scientists scrutinized the fate of the animals. Each of the adult females and new calves from the pen wore radio collars to monitor their movements. Every death was investigated. Other females in the wild were outfitted with GPS collars to track herd behavior and predation. Researchers in low-flying aircraft counted overall numbers each year.
