Walrus Welfare: Overcrowded Haulouts and Climate Stress

Pacific walruses are facing welfare crises from sea ice loss that forces them into overcrowded land haulouts where stampede deaths and stress are increasing.

Key Facts

Pacific walrus populations are estimated at around 129,000 individuals
Walruses traditionally rest on sea ice over the Chukchi Sea between foraging dives
As sea ice retreats, walruses are forced to haul out on land in increasingly large groups
A 2015 haulout at Point Lay, Alaska contained an estimated 35,000 walruses
Stampede deaths — particularly of calves — occur when frightened animals rush toward the water
USGS researchers document walrus welfare through aerial monitoring of haulout behaviour and condition

Welfare Considerations

Walruses forced onto land by sea ice loss experience chronic welfare harms from overcrowding stress and reduced foraging efficiency. Land haulouts require walruses to travel much greater distances to feeding areas, increasing energy expenditure. Calves separated from mothers in stampedes are at high risk of trampling injury or abandonment. Walrus condition (body fat) is measurable from aerial surveys and has been declining as foraging distance increases. Human disturbance of haulouts — including aircraft, boats, and people — triggers stampede mortality events. Climate change is the root cause of walrus welfare decline, with sea ice loss making traditional behaviour patterns increasingly impossible.
