American bison conservation programs balance genetic diversity, population viability, and individual welfare in managed herds, with roundup and handling events requiring welfare consideration for animals that retain their wild behavioral profile.
Bison conservation management involves welfare trade-offs that are navigated with varying success across programs. Roundup and handling events cause acute stress in animals whose flight response is more intense than cattle. The welfare cost of each handling event must be justified by the conservation benefit it achieves. Fertility control methods that reduce herd size without annual roundups offer a welfare-superior alternative where management goals can be achieved without repeated high-intensity handling.
