​Wild beavers are once again living in Cornwall’s rivers for the first time in 400 years, following the county’s first fully licensed release — a milestone not only for Cornwall but for nature recovery efforts across England.

Two pairs of beavers were released yesterday at a Cornwall Wildlife Trust nature reserve in mid-Cornwall, within the Par and Fowey river catchment. The moment follows three years of detailed planning and consultation ahead of the Government’s decision to permit licensed wild releases in England.

Once widespread across Britain, beavers were hunted to extinction in the 16th century. Their return comes at a critical time for wildlife, with one in six species in Great Britain now at risk of extinction. Conservationists increasingly recognise beavers as a keystone species — animals whose natural behaviours reshape landscapes and benefit countless other species.

Through dam-building and wetland creation, beavers restore river systems in ways few other species can. Their work slows the flow of water during heavy rainfall, helping to reduce downstream flooding, while also storing water in the landscape during dry periods, improving resilience to drought. The wetlands they create filter pollutants, improve water quality and provide habitat for a rich array of wildlife, from amphibians and birds to bats and insects.

Lauren Jasper, Beaver Officer at Cornwall Wildlife Trust, said: “We are delighted to have released beavers back into the Cornish landscape. Today is a huge win for nature!”

The licence approval marks the culmination of more than a decade of work by Cornwall Wildlife Trust and its partners. The project has been supported by Natural England, the Environment Agency, Beaver Trust, local landowners and farmers, and funded in part by Cornish business St Eval, alongside donors and members through the Trust’s Wild Beaver Appeal.

Evidence from other parts of Britain shows just how transformative beavers can be. Studies have recorded dramatic increases in biodiversity around beaver wetlands, including significant rises in amphibians, dragonflies and bat activity, as well as marked improvements in plant diversity and bird abundance. By engineering complex wetland habitats, beavers effectively create the conditions for nature to recover at speed.

Dr Rob Stoneman, director of landscape recovery at The Wildlife Trusts, described the release as “a historic moment”, noting that it has passed through a formal application process that could pave the way for further reintroductions across the country.

Beyond biodiversity, the release is seen as part of a wider strategy to tackle the intertwined climate and nature crises. More beaver territories mean greater natural flood management, improved water security and healthier, more resilient catchments — benefits that are increasingly vital as Cornwall faces heavier rainfall events and longer dry spells linked to climate change.

The Trust emphasised that ongoing monitoring and collaboration with local communities will be central to the project’s success. While challenges are expected as people and beavers once again share the same landscape, conservationists believe the long-term gains will be substantial.
​
The return of wild beavers signals a shift in how landscapes are managed — working with natural processes rather than against them. For Cornwall, it represents not just the reintroduction of a lost native species, but a bold step toward restoring rivers, rebuilding wildlife populations and creating a future where nature can thrive once more.
