Genetic management of North American bison herds addresses the legacy of near-extinction bottlenecks while supporting individual animal welfare in managed conservation populations.
Bison genetic conservation involves individual welfare costs at multiple points: capture and testing stress during translocation programs, brucellosis management including vaccination and testing that require repeated handling, and the behavioral disruption of introducing new animals into established herd hierarchies. These welfare costs must be weighed against the long-term population welfare benefits of maintaining genetic diversity and thus disease resistance and adaptive capacity. The conservation welfare calculus for bison management acknowledges that some short-term individual welfare costs are necessary for long-term population welfare and species recovery — but requires minimizing those costs through welfare-conscious handling protocols.
