We’re turning an abandoned fish farm into a beaver paradise
Beavers are nature’s ultimate engineers. By building dams and digging canals they keep water in the landscape; creating a thriving mosaic of deep ponds, complex canals and shallow wetlands. This can increase an area’s biodiversity, reduce flood and drought risks and cut water pollution. But then they were nearly wiped out. In the 1600s, demand for their fur and scent glands skyrocketed. Within the next 200 years, 99.9% of the world’s remaining beavers were hunted and killed. The impact on nature was catastrophic. Without beavers and their dams, that complex, biodiverse landscape was gone, and with it all the life that depended on it.
The mission
Thanks to unconventional conservation methods, beavers have made one of the greatest wildlife comebacks in history. In Poland alone, a population that was considered functionally extinct in the wild just 70 years ago has grown to over 100,000 individuals. Our partner Rewilding Oder Delta is helping secure that comeback. Beyond beavers, they are doing pioneering work to bring back some of Europe’s most iconic wildlife species, including lynx, sea eagles, elk and even the European bison. Now we’ve teamed up with them to create a new home for beavers.



We’re buying a 20-hectare abandoned fish farm in Poland to turn it into a beaver playground. Its lock and drainage channels give them the perfect start for their own construction projects. But bringing them back also means helping people coexist with them as beavers can flood agricultural fields, block drainage ditches, and chew down important trees. That’s why we’re supporting peaceful coexistence with humans by planting 9,000 willow trees, beavers’ preferred snack, and providing protection materials for 300 trees. In the long run, this and our 20 hectares of land will positively impact about 400 hectares of surrounding land.
