What Is 'Rewilding' and How Can It Help Restore Our Planet's Biodiversity?
By Costello et al.
PermaNews Brief
Key Takeaways
Rewilding is a conservation method that enhances biodiversity through natural processes.
- Rewilding supports ecosystem recovery and biodiversity.
- Reintroducing species is key to success.
- Habitat protection is crucial for effectiveness.
- Adaptive management addresses complexity in ecosystems.
- Smart measures mitigate rewilding risks.
Why It Matters
By restoring ecosystems, rewilding fosters resilience and sustainability in our environment.
What to Do Next
Research local rewilding initiatives or biodiversity projects.
Permaculture Context
For permaculture designers and regenerative land stewards, rewilding isn't a distant conservation project happening somewhere else — it's a direct validation of principles most of us already practice, and an invitation to scale them up intentionally. When you stop mowing a field margin, plant a hedgerow, or reintroduce native understory species to a degraded woodlot, you're performing micro-rewilding on your own land. The deeper lesson here is about relinquishing control — one of the hardest shifts for any land manager — and trusting that natural succession, given adequate conditions and connections, will do heavier lifting than any intervention. Practically speaking, this means prioritizing habitat corridors when designing your property boundaries, resisting the urge to "tidy" edges that are actively becoming wildlife habitat, and sourcing native plant species that serve functional roles in your local food web, not just your guild designs. The cautionary note about unintended consequences also reinforces why observation always precedes action in sound permaculture practice — your land has existing relationships worth understanding before you introduce anything new.

This article defines rewilding as a conservation strategy that promotes biodiversity by reintroducing plant and animal species driven from ecosystems, aiming for a holistic return to nature. It explains that rewilding can range from reintroducing apex predators to restoring exploited land, with the overarching goal of allowing natural processes to take control so ecosystems become self-sustaining. The text highlights ecological restoration as a key method, involving the reintroduction of native plant species, tree planting, and the cessation of degrading human activities like resource exploitation and waterway pollution. It identifies the introduction of apex predators as a well-known example of rewilding. The article also addresses the controversies and risks associated with rewilding, citing Costello's warning that ecosystems are so complex that predicting unintended impacts is difficult, and that human efforts to 'fix' environmental conditions can sometimes make things worse. Despite these risks, the article advocates for smart, precautionary measures, such as protecting existing habitats from human exploitation and reconnecting landscapes to facilitate animal migration. This resource provides a balanced view of rewilding, offering specific implementation steps while emphasizing the necessity of precaution and adaptive management in complex ecological systems.
