European rewilding has accelerated dramatically in 2025, driven by the EU Nature Restoration Law, record wolf and lynx population recoveries, and ambitious private rewilding projects. Yet the welfare dimensions of rewilding — for reintroduced animals, prey species, and displaced livestock — remain underexplored in policy discussion.
The EU Nature Restoration Law (NRL), adopted in 2024, mandates that member states restore at least 20% of degraded land and sea ecosystems by 2030, rising to 90% by 2050. This represents the most ambitious ecological restoration commitment in European history and will dramatically expand habitat available for wildlife — with significant implications for both conservation and animal welfare.
Ecosystem restoration affects animal welfare in complex ways:
Europe's wolf population has recovered from near-extinction to over 21,000 animals — one of the world's great conservation success stories. Wolves now inhabit countries where they were absent for a century, including Belgium, Netherlands, Denmark, and Germany. However, this recovery has generated intense political controversy.
Wolf welfare science is developing alongside population recovery. Key findings:
The central welfare tension in wolf country is between wolves (who may suffer from persecution and lethal control) and livestock (who may be attacked by wolves). Evidence-based coexistence measures include:
Eurasian lynx reintroductions are underway or planned across Europe — including successful programs in Switzerland, France, Germany, Czech Republic, and ongoing projects in Scotland and England. Lynx reintroductions involve complex welfare considerations for both the reintroduced animals and prey populations.
Lynx selected for reintroduction face:
Best practice reintroduction protocols now include soft-release enclosures, health screening, GPS monitoring for welfare assessment, and post-release support. Survival rates in well-managed programs are improving.
The European bison (wisent) has been reintroduced across its former range — from Poland's Białowieża Forest to Romania, Germany, and the Netherlands. The species, extinct in the wild in 1927, now numbers over 7,000. Rewilding Europe's bison programs in Romania's Carpathians have demonstrated that large herbivore rewilding can succeed even in populated landscapes.
| Project | Country | Key Species | Welfare Innovation |
|---|---|---|---|
| Rewilding Apennines | Italy | Brown bear, wolf, lynx | Camera welfare monitoring |
| Velebit rewilding | Croatia | Lynx, bear, griffon vulture | Livestock guardian training |
| Danube Delta | Romania | Pelican, sturgeon, bison | Fishing exclusion zones |
| Oder Delta | Germany/Poland | Beaver, white-tailed eagle | River corridor management |
| Cairngorms Connect | Scotland | Beaver, capercaillie, lynx (proposed) | Welfare-based lynx protocol |
Rewilding unavoidably increases predation mortality for prey animals — deer killed by wolves, hares killed by lynx, fish killed by otters. From a welfare perspective, predation causes acute suffering and death for individual prey animals. Some welfare philosophers argue this is relevant; others argue that predation is part of natural systems and that the population-level and ecosystem effects justify individual suffering.
European rewilding in 2025 is at an inflection point — with legal mandates, recovering populations, and growing public support creating momentum, but political backlash from farming communities threatening to slow or reverse progress. Integrating animal welfare science into rewilding practice — monitoring individual animal welfare alongside population metrics — represents an important frontier for the movement.
