Wild beaver filmed on River Dyfi in ‘vastly important’ second

A wild beaver has been filmed on a river in Wales in what has been described as a “hugely significant” sighting.

Beavers disappeared from Britain about 400 years in the past after being hunted to extinction, however prior to now 20 years they’ve been making a return.

Naturalist and presenter Iolo Williams, who encountered the wild beaver at the River Dyfi close to Machynlleth, mentioned the transparent and extended sighting used to be one of the vital “very, very best” issues he had ever witnessed.

There are 4 controlled enclosures that space beavers in Wales, and an unknown quantity residing within the wild.

“I’ve seen some incredible wildlife in Wales, some amazing things, but this ranks up there, not just with the best, but as the very, very best,” mentioned Williams, who captured the instant as a part of his BBC sequence Iolo’s River Valleys.

“The last people to see wild beaver in Wales would have been the Welsh princes, who would have hunted them.

“So they have been absent for centuries. So it is vastly important.”

In Wales, it is an offence to release beavers into open rivers without a licence, and Natural Resources Wales (NRW) said no licences of this type had been issued.

In England, where the government recently approved beavers’ reintroduction to the wild, it is thought that there are about 500 of them living – some in the wild and others in enclosures.

In Scotland, which began reintroducing beavers to the wild several years ago, it is thought that there are now more than 1,500.

“We had data {that a} beaver were observed in this phase of the River Dyfi, and we had been instructed to get to this actual web site at 18:00 and the beaver shall be there,” mentioned Williams.

“We had long past out a couple of days prior to, and it poured with rain and we would observed not anything.

“And I must admit, I was thinking, we’re not going to get it.

“But then once we went at the first dry day, 18:00, and the beaver used to be there.”

Alicia Leow-Dyke, from Wildlife Trust Wales, said there was evidence of the semi-aquatic animals breeding along the waterway.

“On this instance we comprehend it’s one circle of relatives. It might be two households – one circle of relatives cut up into two,” she mentioned.

“There has been proof of breeding at the river. Youngsters were noticed at the river over time.

“Beavers only breed once a year and their litters are pretty small – two to three within a litter. So a beaver family could be anything from two adults, to five or eight if you include the young.”

Last yr the Welsh executive mentioned it used to be making an allowance for introducing regulation to offer protection to beavers, as natural world charities referred to as for them to be launched into Wales’ rivers.

Dr Robert Needham, from the Beaver Trust, mentioned their reintroduction may deliver really extensive advantages, describing them as “ecosystem engineer[s]”.

“What this means is that the sort of habitat modification that beavers can do through damming, building lodges, digging canals – this can create habitats for other species, and they can increase biodiversity,” mentioned Dr Needham.

“They can help restore our wetland habitats, which are massively lost throughout Europe, let alone Great Britain.

“They can lend a hand alleviate flooding with the dams that they invent, specifically in headwater streams, they hang that water again, freeing it slowly. So we see a discount in top float occasions, all through typhoon occasions. But this will also be in reality advisable to villages and society additionally all through all through the summer time classes, all through drought prerequisites.”

But not everyone believes that reintroducing beavers to the wild is a good thing.

Critics say their dams can flood and waterlog fields while the animals themselves can feed on certain agricultural crops and damage trees.

“Fundamentally, there are problems. There are instances the place river banks will fall in and the affect of flooding, specifically on on just right farmland as smartly,” said Aled Jones, president of NFU Cymru.

Iolo’s River Valleys shall be broadcast on BBC Two and BBC One Wales on 6 May at 19:00 and can also be to be had on BBC iPlayer.
