Europe Brings Back 39 Bison and 100+ Species in 2025

Europe just pulled off one of its biggest wildlife recovery years on record, bringing extinct and endangered animals back to landscapes that haven't seen them in generations.

The European Wildlife Comeback Fund supported 23 reintroduction projects in 2025, moving 19 different species across nine countries. Since launching in 2022, the fund has invested over $3 million in wildlife recovery, with nearly $1 million going out last year alone.

The star of the show? European bison, nature's landscape architects. These massive grazers don't just look impressive. They open up dense forests through grazing and trampling, creating meadow and woodland mosaics that other species desperately need.

In Spain's Iberian Highlands, nine bison arrived in a 400-hectare public woodland, welcomed by local residents who see them as living firebreaks. Their grazing reduces wildfire risk while creating jobs and tourism opportunities for the community.

Bulgaria's Rhodope Mountains received eight bison at a site called Zhenda, with plans to grow the herd to at least 50. Dutch nature reserves welcomed four bison bulls from Poland specifically to boost genetic diversity in existing herds.

The biggest release happened in Azerbaijan, where 18 bison returned to Shahdag National Park in early 2026, bringing the total population to around 90 animals. The species had been gone from the region for over a century.

But size isn't everything. The fund supports species based on their ecological impact, not their Instagram appeal.

Cinereous vultures, Europe's largest vultures, got a major boost with 16 birds released across Spain. These nature's cleanup crews specialize in opening large carcasses, giving smaller scavengers access to food while returning nutrients to ecosystems and reducing disease risk.

Even tiny European hamsters made a comeback. Despite their small stature, they're steppe restoration powerhouses, improving soil fertility, dispersing seeds, and creating burrows that shelter countless other species. 100 hamsters were released onto Ukraine's Tarutino Steppe, building populations where they'd nearly vanished.

The Ripple Effect

The fund's success lies in its flexibility. Wildlife reintroductions don't follow neat timelines. Sourcing animals can take years, then suddenly everything moves at once when animals become available.

Traditional funding can't keep pace with that reality. The European Wildlife Comeback Fund can, stepping in at the crucial final stages when animals are ready but money hasn't caught up.

Sophie Monsarrat, Rewilding Europe's Rewilding Landscapes Manager, explains the strategy simply: "We target situations where we will have the biggest impact for wilder nature through the introduction of keystone species."

These animals don't just survive in their new homes; they transform them. Bison sequester carbon and prevent catastrophic wildfires. Vultures prevent disease outbreaks. Hamsters weave together food webs that support dozens of other species.

Local communities benefit too, through ecotourism, reduced environmental risks, and the simple joy of seeing landscapes come alive again.

Europe is proving that extinction doesn't have to be forever, one careful reintroduction at a time.
