Rewilding rests on a simple idea: healthy ecosystems regulate themselves when key species and processes are intact. Rather than managing every detail, you restore the conditions that let predator-prey dynamics run on their own.

The approach has three pillars: large predators to keep herbivores in check, connected habitat so species can move freely, and enough scale for nature to work without constant intervention.

Research shows rewilded landscapes often deliver better ecosystem services than managed ones — more carbon storage, cleaner water, stronger flood protection, and richer wildlife, at lower cost.
