300 Groups Unite to Rewild 2 Million Square Kilometers

A global movement is proving that sometimes the best way to fix nature is to step back and let it heal itself.

The Global Rewilding Alliance now connects 297 organizations working to restore more than 2 million square kilometers of land and 6 million square kilometers of ocean. That's land area roughly the size of Mexico, all being returned to its wild state.

Rewilding works differently than traditional conservation. Instead of constantly managing habitats, these groups bring back missing animals and let nature's engineers do their thing. Beavers build dams that prevent floods and droughts. Large grazing animals help plant communities recover by trampling and fertilizing the soil. Predators keep ecosystems balanced.

The results are remarkable. In Wyoming, beavers nearly wiped out by settlers are coming back and rebuilding wetlands. Their dams now support hundreds of other species. In Brazil, primates are returning to national parks. South African conservationists are restoring entire savanna ecosystems in the Kalahari.

"The first time we talk to an organization, there's often tears," says Alister Scott, the alliance's executive director. Rewilders working in isolation from Brazil to Australia tell him how relieved they feel to finally connect with others doing similar work.

The science backs up their efforts. Research shows that bringing back wild animals can double the carbon an ecosystem stores, sometimes increasing it up to 12 times. Birds are returning to once-abandoned areas. Fish are thriving in protected ocean zones. Animals thought locally extinct are reappearing.

The Ripple Effect

The alliance launched in 2021 specifically to end that isolation. Now these 300 groups share knowledge through task forces focused on wetlands, rangelands, and grasslands. They're learning from each other's successes and helping new rewilding projects get started faster.

This collaboration matters more as the world works toward protecting 30% of Earth's land and oceans by 2030. Rewilding offers a proven path forward that's less expensive than intensive habitat management and more effective at fighting climate change.

The movement shows that nature knows how to heal itself when given the chance and the right tools. Those tools are often the wild animals we removed in the first place.
