The Arctic wanderers: caribou in a changing north

Caribou and reindeer are of great importance to both Indigenous Peoples and Arctic ecosystems. They fertilize the ground, keep shrubs and trees at bay with their grazing, and are a source of food and culture for the communities in the north. In an ever-warmer Arctic, caribou and reindeer are both vulnerable to climate change and might also be part of the solution.

This issue of the Circle examines how the behaviour of caribou and reindeer is changing in a warmer Arctic, how knowledge from Indigenous peoples can be combined with scientific data, and why some Svalbard reindeer are thriving despite climate change. All of these stories and more can be found in this magazine.
