Chris Jones stands on a beaver dam, and plunges a stick deep into the pool that has fashioned behind it.  He pulls out the stick, which is now caked in over a metre of silt. “All this could in any other case move into the oyster beds in Falmouth” he says. “The beavers are doing the work of the South West Water authorities for them.”

Beavers, I study over the course of a extremely satisfying and instructive weekend in Cornwall, are extra than simply low cost labour: given an opportunity, they might play a significant position in saving our surroundings. And Jones is a uncommon chicken– a pioneering farmer and a director of the Beaver Belief, who advocates for the reintroduction of those buck-toothed rodents (Castor fiber, to offer them their Latin identify) into our rivers. Technically, they’ve been extinct from this habitat for 400 years.

At Jones’s Woodland Valley Farm, in a barn heady with the perfume of mildly fermenting hay, our beaver-themed weekend begins with a presentation of some alarming ecological statistics: the 2015 floods value Britain £5bn; greater than 1 million hectares of wetlands had been drained within the Seventies; solely 14 per cent of our rivers are in good ecological situation. On high of this, we have now misplaced 50 per cent of our wildlife, together with keystone species and essential pollinators, and Defra warns there are solely 30-40 years of soil fertility left. The record goes on.

It was in response to those threats, that Chris Jones turned his 170-acre farm natural in 2003 – and, in 2014, conceived the Cornwall Beaver Challenge. Three years later he launched two grownup beavers right into a five-acre enclosure on his land“By constructing dams, beavers regulate water move, thereby decreasing danger of flood and drought,” explains Chris. “They gradual the move of water and enhance water high quality as dangerous nitrates and phosphates settle into the sediment. The wetlands they create additionally seize 3 times extra carbon than drier meadows – and might create pure fire-breaks.” 

The wetlands, furthermore, assist ecosystems the place different species can flourish.

Chris now has 5 of the creatures beavering away on his land. We stroll by the woods to see the impact of their work over the previous 4 years, seeing big piles of sticks, branches and stones piled higgledy-piggledy into porous dams that permit each water and fish to go by. Now stable as bridges, the dams assist vegetation on their floor. Swimming pools have additionally fashioned above them, whereas the streams have expanded their course to create wetlands. The realm – with dappled daylight falling by the tangle of untamed vegetation – is alive with birdsong and contemporary plant progress.

Throughout, we see proof of the beavers’ industrious carpentry: bushes teeter precariously, their trunks chopped into X-shapes with axe-like precision by the beavers’ vibrant orange, iron-clad tooth. Willows – the beavers’ favorite meals – are stripped of their bark. Gnaw-marks, like chiselled notches, abound.

The reintroduction of beavers shouldn’t be with out controversy. “Folks complain that beavers destroy bushes, however that is pure coppicing – a conventional methodology of woodland administration,” says Chris in defence of the undertaking. “Beavers want bushes and wouldn’t destroy their very own habitat – they’re wonderful at environmental administration.”

Some anglers complain that beavers eat the fish they’d in any other case catch. “A typical false impression, due to CS Lewis’ Chronicles of Narnia,” laughs James Wallace, chief govt of the Beaver Belief, who accompanies us. They’re actually completely vegetarian. Which isn’t to say there will not be actual considerations right here, too.

“Farmers concern for his or her crops and their livelihoods,” explains James. He sees it as a part of the belief’s position to assist landowners and mitigate the extra troublesome influence of beavers. “We seek the advice of with native events – farmers, fisheries, foresters – hearken to their considerations, and encourage a balanced dynamic between people and nature.”

Merlin Hanbury-Tenison, the proprietor of Cabilla – an property on Bodmin Moor that hosts common retreats – takes issues even additional. “We purpose to revive our 200 acres of farmland to its pure state of equilibrium, because it was earlier than human intervention,” he tells me, including: “Beavers are step one in our technique”. That’s why, a 12 months in the past, he welcomed Sigourney Beaver and Jean-Claude van Dam onto his land.

Our group spends an evening glamping in stylish tents on his property earlier than Hanbury-Tenison leads us on a daybreak stroll by woodlands to Cabilla’s beaver enclosure. They’ve already created dams on its streams, and my hope was to fulfill these crepuscular creatures at work – hauling logs with their entrance tooth and staggering underneath the load of rocks of their paws. However their night time’s work is finished – Sigourney, after we discover her, is fortunately enjoying together with her kits within the pool she has created, surrounded by an idyllic forest of willow, rowan and oak.

At current, beavers are protected in Scotland however not in England, the place there might be as much as 500 dwelling in 5 river catchments. It isn’t at present permitted to launch them into the wild. However their future is trying rosy. “It’s hoped beavers will likely be protected and welcomed again into the wilds of England, underneath licence, subsequent 12 months,” says Wallace. On 25 September the federal government introduced a programme to incentivise farmers to create nature corridors alongside rivers, which can give area for beavers to proceed their ecological engineering. For Wallace, the transfer can’t come shortly sufficient: “We’re in a local weather and extinction emergency, and it’s time for us to work with one another, alongside nature.”
