Wildlife Rescue and Rehabilitation: Release Criteria and Success

Wildlife rehabilitation success depends on applying rigorous criteria for release readiness that prioritise animal welfare and survival prospects over emotional attachment to individual animals.

Key Facts

Only an estimated 30-50% of admitted wildlife casualties are successfully rehabilitated and released in most species
Release criteria include body condition, independent feeding, flight or flight response, and species-appropriate behaviour
Soft release protocols using pre-release enclosures at the release site improve post-release survival
Some species including foxes, deer, and birds of prey require specialist rehabilitation expertise
Keeping wildlife as permanent residents when release is impossible requires high-quality care meeting their complex needs

Welfare Considerations

Wildlife rehabilitation involves difficult welfare decisions. Investing intensive resources to rehabilitate animals that are unlikely to survive or thrive post-release may cause more suffering through the rehabilitation process than would early euthanasia of animals with poor prognoses. Rigorous honest assessment of release prospects serves animal welfare better than optimistic rehabilitation attempts. Where animals genuinely cannot be released, the decision to keep them as permanent residents requires honest evaluation of whether an appropriate quality of life can be maintained, or whether euthanasia is the kindest option.

What You Can Do

Contact a licensed wildlife rehabilitator rather than attempting to care for wild animals yourself
Support wildlife rehabilitation organisations financially and through volunteering in appropriate roles
Advocate for standardised release criteria and post-release monitoring in wildlife rehabilitation practice
Engage with your local rehabilitation network to understand what species they can and cannot help with
Support research into post-release survival rates to improve rehabilitation protocols
