Eurasian lynx have been successfully reintroduced to parts of Europe after centuries of extinction. The UK is considering reintroduction as a rewilding measure, with debates about prey impacts and livestock predation ongoing.
Lynx reintroduction welfare considerations include both the welfare of reintroduced individuals and the welfare of prey species affected by predation. Individual lynx released into new territories face adjustment challenges including establishing territories, finding prey, and avoiding human infrastructure. Soft-release protocols using temporary enclosures in release areas reduce initial mortality compared to hard releases. The ecological argument for reintroduction includes welfare benefits for overabundant deer populations that suffer during harsh winters when population size exceeds habitat carrying capacity. Natural predation maintains deer populations below overabundance thresholds, reducing winter starvation. Livestock predation events, while uncommon, cause genuine welfare harm to affected animals and economic harm to farmers.
