Zoo Polar Bear Thermal Welfare Management

Polar bears are highly adapted to Arctic cold and face significant welfare challenges in temperate and warm climate zoos.

Key Facts

Polar bears have the densest fur of any bear and black skin beneath white guard hairs for heat absorption
They are physiologically adapted to Arctic temperatures and can show heat stress above 10 degrees C
Outdoor pools and artificial cooling are essential in warmer climates
Stereotypic pacing is particularly common in polar bears in inadequate environments
Enrichment including ice blocks, frozen food, and large deep pools reduces stereotypies
Some zoos have reduced or eliminated polar bear exhibits due to welfare concerns in warm climates

Welfare Considerations

Polar bear welfare represents one of the most challenging cases in zoo animal management. The species' thermal physiology and natural ranging behaviour create inherent limitations in any zoo setting. Zoos in temperate or warm climates must provide aggressive cooling, large pools, and comprehensive enrichment. Some facilities have concluded that polar bear welfare cannot be adequately met in their climate.
