When nine European bison crossed into a 400-hectare woodland in Spain's Iberian Highlands in 2025, it marked more than a species comeback—it marked a shift in how Europe funds the wild's return. The European Wildlife Comeback Fund, launched by Rewilding Europe in 2022, is making wildlife reintroduction less of a gamble and more of a reliable tool for ecological restoration, and 2025 proved just how much flexible funding can accomplish.
Wildlife reintroductions are unpredictable by nature. Animals must be sourced, transported, and released in windows that rarely align with annual budgets. Traditional grant cycles demand certainty; animals demand patience. The EWCF was designed precisely to bridge that gap, providing adaptive funding that moves when opportunities emerge. As Sophie Monsarrat, Rewilding Landscapes Manager at Rewilding Europe, puts it: "The Fund is a flexible tool that supports the last steps of translocations, targeting situations where we will have the biggest impact for wilder nature through the introduction of keystone species."
This year, the fund supported 23 reintroduction initiatives across nine European countries, involving 17 species. Since 2022, it has committed more than €3 million to wildlife recovery, with nearly €1 million deployed in 2025 alone. The results speak across landscapes: from Shahdag National Park in Azerbaijan, where 18 bison arrived in early 2026 to bring the population to around 90 animals—over a century after the species vanished from the region—to the Rhodope Mountains of Bulgaria, where eight bison were released into a 3,800-hectare site called Zhenda, with the aim of growing that population to at least 50.
But the EWCF's reach extends far beyond bison. Vultures, hamsters, horses, and trout all feature in the fund's portfolio, selected not for their size but for their ecological weight. Cinereous vultures—Europe's largest vulture species—are nature's essential sanitation workers, opening large carcasses that grant access to other scavengers and decomposers, returning nutrients to ecosystems while reducing disease spread. Each species chosen operates as a keystone, exerting disproportionate influence on its habitat.
In Spain's Iberian Highlands, the bison releases weren't met with indifference. The El Recuenco council and local residents warmly welcomed the animals, seeing them not just as wildlife but as landscape architects and economic drivers. By grazing, browsing, and trampling, bison create a mosaic of meadow and woodland while sequestering carbon and reducing catastrophic wildfire risk. For communities, that translates to jobs, income, and transformed land. In the Dutch rewilding sites of Maashorst, Veluwe, and Kraansvlak, four bison bulls brought from Poland improved the genetic diversity of existing herds, strengthening populations for the long term.
What distinguishes the EWCF isn't novelty—rewilding has been underway for years—but its pragmatic approach to a fundamental problem: the mismatch between how conservation is funded and how nature actually works. By remaining flexible and responsive, the fund has enabled 39 bison released across four countries in a single year, alongside dozens of other species moving back into landscapes across Europe. That adaptability may seem like a small institutional change. In practice, it's the difference between ambition and lasting ecological recovery. As Europe's wildlife makes its comeback, that flexibility increasingly looks like the future of conservation itself.
