Walrus Welfare: Sea Ice Loss and Haulout Crowding in the Arctic (2026)

Walruses depend on sea ice as resting platforms between feeding dives, and its decline forces massive numbers onto land haulouts where crushing injuries and stampede deaths cause significant welfare harms.

Key Facts

Pacific walrus populations use sea ice in the Chukchi Sea as resting platforms — as ice retreats north beyond diving range, they haul out on Alaskan and Russian beaches
Haulouts of 35,000+ animals on small beaches cause density-related crushing deaths, particularly of calves
Disturbance by aircraft, vessels, or polar bears causes mass stampedes that result in calf mortality
The IUCN lists Pacific walrus as Vulnerable with climate change the primary threat driver

Welfare Considerations

Walrus calves crushed in stampedes die from traumatic injury — a welfare harm directly caused by climate-driven habitat loss. Animals forced to haul out on unsuitable substrate (steep rocky beaches rather than gentle sandy beaches) expend more energy and sustain more injuries. Long swims from disappearing ice to distant shorelines exhaust calves unable to maintain the pace of adult females. Disturbed haulouts that stampede into the sea at night drown weaker animals. Each of these welfare harms is traceable directly to greenhouse gas emissions driving Arctic sea ice loss.

What You Can Do

Support WWF Arctic climate change advocacy connecting walrus welfare to emissions reduction policy
Advocate for no-fly zones above haulout sites during the August-October critical period
Donate to US Fish and Wildlife Service walrus monitoring and haulout management programmes
Raise awareness that walrus welfare is directly harmed by climate inaction
