The West Moberly and Saulteau First Nations identified predation as a significant limiting factor faced by the caribou in a highly fragmented landscape with dwindling population numbers. They observed that vulnerable caribou calves were falling prey to wolves, further jeopardizing the survival of the species. In light of this pressing concern, their overarching objective became to enhance the reproductive success of adult female caribou and increase the chances of calf survival.
They implemented two emergency-level actions In 2013, they took proactive measures to reduce predator density to a level that would be more compatible with the survival of caribou. Furthermore, in 2014, they initiated a maternal penning program, a collaborative effort led by the First Nations with support from scientists. This program specifically focused on enhancing the survival rates of female caribou and their vulnerable calves.
Dedicated First Nations guardians undertook the crucial task of monitoring and supervising the caribou within the pen around the clock, residing alongside them, providing food, and ensuring their overall well-being. The enclosure, spanning 30 acres and encircled by electric fencing, allowed the caribou to forage naturally while also providing some supplementary feeding when necessary. The guardians diligently maintained the enclosure, inspected for predator tracks, and monitored surveillance cameras to ensure the safety and welfare of the caribou population.
