Wildlife rescue and rehabilitation organisations care for millions of injured and orphaned wild animals annually. Welfare principles governing rehabilitation decisions including when to treat, when to euthanase, and when to release, are fundamental to ethical wildlife care.
Wildlife rehabilitation ethics require integrating welfare considerations throughout treatment decisions. Animals with poor prognosis for welfare-positive survival should be humanely euthanised rather than subjected to prolonged treatment that extends suffering without reasonable hope of recovery. This decision requires clear welfare assessment criteria and the courage to prioritise animal welfare over human emotional desire to save every animal. Animals suitable for rehabilitation face welfare challenges during the captivity period including stress from handling, unfamiliar environments, and medical procedures. Release decisions must ensure animals are genuinely fit for wild survival, as releasing welfare-compromised animals creates suffering in a different context. Long-term captivity causing habituation to humans creates release risks that must be balanced against individual welfare.
