Wildlife rescue involves ethical decisions about when to intervene, how to minimize harm during rehabilitation, and how to assess outcomes for individuals versus populations and ecosystems.
Wildlife rescue and rehabilitation involves a genuine ethical and welfare dilemma. Intervention imposes welfare costs - stress of capture, handling, captivity, veterinary procedures - that must be justified by a reasonable probability of successful recovery and release. Well-intentioned rescues of animals that would have recovered naturally, or that have injuries incompatible with survival, impose welfare costs without welfare benefit. The welfare framework for rehabilitation decisions must include honest assessment of prognosis, species-specific welfare requirements in captivity, and whether the individual's welfare is better served by treatment or euthanasia. Licensed rehabilitators make these decisions within professional frameworks that the public often doesn't understand.
