Module 8
Conservation & Indigenous Knowledge
Polar bears are IUCN Vulnerable, listed under the US Endangered Species Act, and governed by the 1973 Polar Bear Range States Agreement. Global population is ~26 000 across 19 subpopulations; the trend is increasingly negative for southern populations. Indigenous Inuit and Chukchi knowledge is critical to monitoring and quota setting.
1. The 1973 Agreement & PBSG
The five range states (Canada, USA, Russia, Norway, Denmark/Greenland) signed the 1973 Agreement on the Conservation of Polar Bears, restricting international trade, banning aerial hunting, and committing to subsistence-only Indigenous harvest. The IUCN Polar Bear Specialist Group (PBSG) coordinates monitoring and issues consensus population estimates. Quotas in Canada and Greenland are co-managed with Inuit Land Claims Organisations; Russia permits only subsistence hunting.
2. Indigenous Knowledge Integration
Inuit Qaujimajatuqangit (Inuit traditional knowledge) provides decadal-scale observations that complement scientific surveys. Indigenous harvesters report bear body condition, movement patterns, and human-conflict incidents that satellite telemetry often misses. Co-management of Nunavut quotas since 1999 integrates IQ formally; the success of quota changes in Foxe Basin and Davis Strait depended on this integration (Dowsley 2009).

3. Human-Bear Conflict
As sea ice retreats, starving bears come ashore earlier and more often. Churchill (Manitoba), Arviat (Nunavut), and Kaktovik (Alaska) have become documented conflict hotspots. Conflict responses include “bear jails” (temporary holding for translocation), aversive conditioning, bear-dog patrols, and community-waste management to remove attractants. Lethal removal is a last resort but documented; Wilder 2017 catalogued fatal human-bear encounters, showing an increasing trend with ice-free season length.
4. Synthesis of the Course
Eight modules traced the polar bear from phylogenomic origin to conservation status. The species is the most specialised ursid on the planet — white- coated, seal-eating, sea-ice-dependent — evolved in a geological blink and dependent on a habitat that is disappearing within the same century that it was first described. Conservation requires both climate action (M6) and sustainable co-management of what ice remains. The biology laid out across modules 0–7 is what hangs on that politics.
