Rewilding and Wildlife Welfare: Opportunities and Challenges

How rewilding programs that restore species and ecosystems affect the welfare of individual animals, from reintroduced predators to prey populations.

Key Facts

Rewilding aims to restore ecological processes and species to depleted ecosystems
Wolf reintroduction to Yellowstone changed river dynamics through trophic cascade effects
Lynx reintroduction programs are underway or proposed in UK, Germany, and several other European countries
Reintroduced animals face high mortality in early post-release periods
Prey species like deer may experience changed welfare dynamics as predator pressure returns

Welfare Considerations

Rewilding creates interesting welfare tensions. Reintroduced predators face high post-release mortality as they learn to hunt in unfamiliar landscapes. Prey species that have been predator-naive face novel fear and risk that may reduce their welfare. Yet restored predator-prey dynamics also create benefits - prey populations in better body condition through fitter individuals, reduced disease through natural selection, and population control that prevents starvation during harsh winters. The welfare calculus of rewilding requires thinking beyond individual animal welfare to ecosystem welfare and the long-term welfare of future populations.

What You Can Do

Support well-planned rewilding projects with proper monitoring and adaptive management
Engage with the welfare implications of predator reintroduction alongside conservation benefits
Advocate for post-release monitoring that includes individual animal welfare assessment
Support compensation schemes for farmers affected by rewilded predators
Consider rewilding a welfare intervention for entire ecosystems, not just a conservation tool
