Wildlife disease intervention balances welfare concerns for individual animals against ecological and management considerations. Understanding when and how to intervene guides welfare-sensitive wildlife management.
Wildlife disease intervention welfare involves difficult decisions about which diseases warrant intervention and which should be left to natural processes. White-nose syndrome, which has devastated North American bat populations, has driven researchers to develop antifungal treatments and habitat modifications that protect bats without requiring individual treatment of enormous populations. Chronic wasting disease in deer presents a different challenge - no treatment exists, and culling programs reduce transmission but cause welfare harms to culled animals. The welfare framework for intervention decisions includes consideration of disease severity, individual welfare impact, feasibility of intervention, ecological consequences, and costs. Intervention is most clearly warranted when anthropogenic factors introduced or accelerated the disease.
