What Is Rewilding?

Rewilding is a progressive approach to conservation that focuses on restoring natural processes and self-sustaining ecosystems, rather than simply managing landscapes to maintain a particular state. Unlike traditional conservation, which often aims to preserve a historic snapshot of nature, rewilding embraces dynamism — allowing ecosystems to evolve, expand, and self-regulate.

The core idea is straightforward: reduce human control, reintroduce missing species where appropriate, and let nature do the work.

Key Principles of Rewilding

  • Restoring trophic chains: Bringing back predators and large herbivores that once shaped ecosystems creates cascading ecological benefits throughout the food web.
  • Reconnecting habitats: Wildlife corridors link fragmented patches of habitat, allowing species to move, disperse, and maintain genetic diversity.
  • Reducing intervention: Over time, rewilded areas require less and less active management as natural processes re-establish themselves.
  • Engaging local communities: Successful rewilding projects involve and benefit local people, often through ecotourism and sustainable land use.

Notable Rewilding Projects in Europe

Rewilding Europe

Founded in 2011, Rewilding Europe is the continent's leading rewilding organisation, working across multiple landscapes from the Danube Delta to the Scottish Highlands. Their model combines species reintroduction, habitat restoration, and the development of nature-based economies that give communities a financial stake in conservation.

The Knepp Estate, England

Perhaps the most celebrated rewilding story in the UK, the Knepp Estate in West Sussex was a conventional farm that was transformed into a rewilding project from the early 2000s onward. After introducing free-roaming longhorn cattle, Tamworth pigs, Exmoor ponies, and fallow deer as proxies for lost megafauna, the land rapidly transformed. Turtle doves, peregrine falcons, purple emperor butterflies, and nightingales — all declining species — returned and thrived. Knepp now hosts safaris and generates income through nature tourism.

Wolf and Lynx Recovery in Europe

Across Central and Western Europe, wolves and Eurasian lynx are naturally recolonising areas from which they were extirpated centuries ago. In countries including Germany, France, the Netherlands, and Belgium, wolf packs have re-established without direct reintroduction, simply by dispersing from recovering populations in Italy and Poland. This natural rewilding is reshaping how European countries think about coexistence with large carnivores.

Rewilding and Climate Change

Rewilding is increasingly recognised as a powerful nature-based solution to climate change. Restored forests, wetlands, and peatlands sequester significant amounts of carbon. Beavers, for example, create wetlands that store both water and carbon, reduce flooding downstream, and support exceptional biodiversity — all through their natural dam-building behaviour.

Challenges and Criticisms

Rewilding is not without controversy. Key challenges include:

  1. Human-wildlife conflict: Large carnivore recovery brings genuine challenges for farmers and livestock owners that must be addressed with practical support and compensation schemes.
  2. Land availability: Large-scale rewilding requires land, which can conflict with agricultural and housing needs, particularly in densely populated regions.
  3. Defining "wild": Deciding which historical baseline to restore to, and which species to prioritise, involves difficult choices with no purely scientific answer.

What You Can Do

Rewilding doesn't only happen at landscape scale. Gardens, churchyards, school grounds, and urban green spaces can all be managed in ways that support biodiversity — reducing mowing, planting native species, creating log piles, and installing ponds. These small actions, multiplied across millions of properties, contribute to a greener, wilder world.
