The UK has one of the worst records of any country in the world for protecting its historic biodiversity. This should come as no surprise to those of us who live on this crazy, crowded island where caring for the natural world has traditionally played second fiddle to making a quick buck. But the tide is beginning to turn: up and down the country many of us are fighting back, seeking to look after what we still have and, where possible, to reintroduce what we have lost. Which brings me to the inspiring story of Derbyshire’s beavers.
If the experts are to be believed, beavers were wiped out in my home county around 800 years ago. Now I’m not sure quite how they know that, I can’t quite believe that one of the local lords recorded the event for posterity in his diary, writing something like “Great news, just exterminated the last beaver in Derbyshire, so now our trees will be safe forever…until, that is, we want to chop them down for firewood, or to make floorboards or beer barrels or whatever.”
To be honest, the exact date doesn’t really matter. The incontestable fact is that, following the end of the last Ice Age, beavers were common hereabouts for many thousand of years, before becoming extinct in the Middle Ages.
On one level, the extinction of the beaver can be seen simply as the regrettable loss of one of this island’s few cuddly mammals, a mammal guaranteed to elicit sighs of “Ah, so cute” from ordinary folk encountering them going about their daily business in the wild. But there’s more to it than that. Beavers are landscape engineers, a keystone species that shapes environmental conditions in a manner beneficial to countless other species.
By digging canal systems and damming water courses, beavers create diverse wetland areas, places where fish can safely spawn and other animals such as otters, water voles and water shrews can make their homes. Insects thrive in the waterways constructed and maintained by beavers, and these in turn nourish a range of bird species. In creating suitable habitats for themselves, therefore, beavers help create robust ecosystems in which a whole range of species can flourish.
But it’s not just wildlife that benefits from these hefty rodents beavering away in the countryside – there’s a payoff for humans too. It is argued that beaver dams improve water-quality by acting as filters which trap soil and other pollutants washed into rivers from surrounding farmland. The ponds created by beaver dams also impact on the flow of rivers, and can help mitigate downstream flooding after periods of heavy rain.
Given these credentials it’s no surprise that environmental organisations have long been keen to see beavers reintroduced to the UK. Scotland led the way, and there are spots there where animals reintroduced from continental Europe are already thriving. In England the first major reintroduction initiative was in Devon, led by Devon Wildlife Trust in partnership with a range of other interested parties.
Having watched for several years the success of beaver reintroductions in other parts of the country, Mrs P and I were thrilled when our local conservation organisation – Derbyshire Wildlife Trust – announced its own plans for a project at the Willington Wetlands Nature Reserve in the south of the county. When the Trust appealed for donations to help fund the initiative we were pleased to help.
Progress stalled for a while due to disruption caused by the Covid pandemic. But at last, a few weeks ago, we got an email from the Trust inviting us to sign up to attend an online event at which a pair of beavers would be released into their new Derbyshire home. The animals had been captured on the River Tay in Scotland, where the species is now doing very well. After a period of quarantine and some health checks the beavers were transported to Derbyshire in special wooden crates on the back of a pick up truck.
The release of the two animals went perfectly. We’d feared they would dash for the water the second the doors of their crates were opened, and immediately dive to disappear from view. Instead they took their time, seemingly untroubled by the stress of their long road journey, and put on a bit of a show for their adoring online fans. Huddled around our laptop at home, it was a privilege to watch the images of history being made just a few short miles away. At last, after an absence of some 800 years, beavers were back in Derbyshire!
A couple of weeks later the Trust released a second pair of beavers into their enclosure at the Willington Wetlands Nature Reserve, The enclosure is surrounded by a specially designed beaver-proof fence and large enough at 40 hectares, or just shy of 100 acres, to allow the animals to live entirely natural lives. The brook flowing through the enclosure guarantees a suitable wetland habitat, and a wide range of native plants and trees will offer the beavers all the food they need to live long and happy lives.
With a bit of luck, next year we will be celebrating the first beavers to be born in Derbyshire since the Middle Ages!
