American bison were reduced from an estimated 30-60 million to fewer than 1,000 individuals by 1890 through systematic hunting. Recovery has been remarkable — over 500,000 bison exist today — but most are commercially farmed rather than truly wild, raising distinct welfare questions across different management contexts.
Bison welfare depends significantly on management context. Truly wild conservation herds face primarily ecological welfare challenges — predation, weather, competition for forage — and have largely recovered natural behavioural repertoires. Yellowstone bison culled at park boundaries experience capture stress, transport, and slaughter — welfare harms driven by brucellosis management politics rather than ecological necessity. Commercially farmed bison face handling, branding, and slaughter welfare concerns comparable to cattle, though extensive management typically provides better welfare than intensive systems. Indigenous-led conservation herds often prioritise holistic approaches that integrate ecological and cultural values with individual animal welfare. The restoration of bison to grasslands is also a wild animal welfare story: restored herds provide habitat for prairie species whose welfare collapsed with the original bison decline.
