YORK: Council would consider reintroducing beavers to Ouse

It follows more than 20 flood warnings in York and North Yorkshire and numerous businesses being forced to close due to recent flooding.

Councillors are set to approve a £5.3 million flood alleviation scheme on December 17, but the City of York Council’s flooding team is also open to further measures including beaver reintroduction. 

The council’s innovative flood resilience manager Victoria Murray leads the Ousewem project, which focuses on mitigating flooding from the Ouse.

She said: “At present, we have no live plans to introduce beavers as part of water level management for the Ousewem project; however, we and partners are open to and continuing conversations about the reintroduction of beavers.”

Ms Murray added that while “beavers offer fantastic, natural benefits to flood and drought reduction, water quality and biodiversity” to reintroduce them to the Ouse would require “a significant amount of water to be stored across the entire 3,500km² catchment to have an impact on flood peaks".

Jeff Davitt, a trustee at the Yorkshire Rewilding Network, said there could be benefits to reintroducing beavers.

He said: “At the moment, in much of Yorkshire, the water drains off the land quickly into the rivers way up in the north and most of it heads down through York.

“Any time a study is done with the limited population [of beavers] that’s there, they see a big reduction in the peak flows.

“So the water obviously comes through but rather than there being a massive spike, it’s more rounded.”

According to Forestry England, beavers were heavily hunted for their fur and scent glands that produce a substance called castoreum and by the beginning of the 16th century the beaver became extinct from the UK.

Beverley, in the East Riding of Yorkshire, is believed to be named after its beaver population. 

Dr Rob Stoneman, director of landscape recovery for The Wildlife Trusts, advised against introducing beavers in York, saying it was too close to pumped drainage systems in the lowlands. 

“I would start beaver introductions in the upper catchments of the Ouse, i.e. the Dales, and let them spread downstream, so that by the time they got to the drained arable lowlands, beaver co-existence would be weaved into the way we manage land rather than surprise or annoy farmers whose fields suddenly flood because a beaver has burrowed through a dyke. 

“Moreover, they would have the best flood mitigation impact upstream of York.”

Beavers were reintroduced to Lincolnshire for the first time in more than 400 years in December. 

Wild beavers are now in Argyll, Tayside and Devon.

In 2014, The Guardian reported that the reintroduction of beavers to the wild in Scotland for the first time in 400 years had been an “outstanding success” according to the team of ecologists that brought them back.

The report added that the four pairs of beavers reintroduced in Knapdale in 2009 produced 14 young, engineered 18-metre-long dams and lodges the size of double garages and significantly boosted tourism in five years.
