There is something distinctive about the willow trees around Loch Barnluasgan. Every few metres you come across one which seems to have been sculpted – there is a ridged indent at the base of the trunk and a pile of large wood chips below. Sure signs that the local beavers have been at work.

Next year will mark five years since the end of the Scottish Beaver Trial, a high profile project that re-introduced a handful of beavers to Scotland after around 400 years absence.
The trial’s success resulted in the decision to allow the pairs, which were released in Knapdale, near Lochgilphead, to remain, and two years ago the Scottish Government announced that it believed beavers should be allowed to expand from that area naturally.
Since then, attention on the project may have declined, but the beavers certainly haven’t. This spring, Bjorna, one of the original males and his mate Millie, added three new kits to the population. His family of six on Loch Barnluasgan are among a total of 20 on the surrounding hill lochs.
“Beavers are known as a keystone species, which means that they shape the environment around them,” explains Ben Harrower, of Scottish Beavers. “They engineer impressive structures including dams, lodges and foraging canals and are able to create new wetlands that support other wildlife.
“The trial helped us to develop a lot of knowledge about their biology and habits, and to find out what effect they would have on the environment around them.”
The original Scottish Beaver trial was a partnership between the Scottish Wildlife Trust, Forestry Commission Scotland and the Royal Zoological Society. After several year of groundwork, it began in 2008 with a focus on exploring the effect the beavers would have on the environment. In Knapdale, it found that beavers created more than 13,000 square metres of new wetland and standing deadwood, benefiting a huge range of wildlife.
With their giant incisors and paddle-shaped tails, these endearing vegetarians have had other effects too – providing a boost to tourism by attracting visitors to the region, and giving local wildlife education a new focus.
Both benefits are facilitated by Heart of Argyll Wildlife, an organisation set up by rangers Pete Creech and Oly Hemmings, which offers wildlife workshops and guided walks that have the power to turn passing curiosity into passion.
West Coast Review joined them just before dusk, for one of their last Beaver walks of the 2018 season.
“Beavers are amazing animals, and a wonderful example of the interconnectivity of all living things,” says Pete, who has been involved with the Beaver Trial since its inception.
“They are eco-engineers, opening up areas of riparian woodland, increasing forage by creating layers of woodland, and regenerating tree species via their coppicing activities.”
Understanding the nature of this coppicing answers some of the long-standing concerns about the impact of the beavers.
Their reputation for felling trees had preceded them, but, as the evidence we see around the loch confirms, while they harvest bark and branches for food and construction, and will undoubtedly make an impression on a tree trunk, it is unusual for them to fell an entire tree – most trees survive and thrive long after the beavers have been at work.
Viewing their impressive dam and lodge constructions, and listening to the slap and splash of what might have been a tail on the water, were the closest that we got to a live beaver encounter during our walk, but we were unlucky on that front, as they have been sighted, usually swimming, on the majority of this year’s beaver walks.
For Pete, whose work takes him to the lochside at quieter times, there have been closer encounters. “I nipped down to Loch Barnluasgan one evening after setting a moth trap and within a couple of minutes one of the beavers came up to within a metre of where I was standing.” he says.
Further insight into the beavers’ lives come from night camera footage, which recently recorded the group enjoying a family grooming session, and Bjorna demonstrating his balance as he walked out of the water on his hind legs, using his front paws to carry sticks.
The last few weeks have been particularly busy, as the beavers reinforce their lodge and store food ready for winter. Now, though beavers do not hibernate, they will start to retreat inside, where they will mostly remain until spring.
When the beaver trial began, there was scepticism about the landscape changes they would bring, but experience in Argyll has largely shown these to be positive, and that where work such as dam building brings challenges, it can be managed with the correct tools and approach.
A Government consultation published in October found 83 per cent of respondents were supportive of the reintroduction policy (and the steps identified to mitigate its potential impacts), but though the Government has been widely supportive of the project, those involved believe that support has not gone far enough.
“Beavers need to be given European Protected Status, and there should be clear rules about how they can be managed,” says Ben Harrower. “That would allow them to thrive and expand their range in Scotland and also ensure that where they need to be managed this is done proportionately, humanely, and within the law.”

Did you know…
-
Beavers store fat in their tails which get bigger in summer and lose weight over winter.
-
Beaver teeth are a yellowy colour because of the thick enamel which contains iron to keep them strong.
-
Beavers are sociable creatures and groom each other.
-
Beavers have especially dexterous front paws, like hands, for carrying materials. Instead of thumbs they have a semi-opposable little fingers.
-
A beaver’s life expectancy is between ten and fifteen years in the wild.
-
Adults can grow to around 1metre long with their tails up to another 50cm



The idea of marking the days of advent with books is not new – it has become popular to give young children a picture story to unwrap on each day leading up to Christmas – but a new book from Camilla Victoria Storm and Nick Simons applies this countdown principle to a cheerful chapter book. It’s a fresh approach that works very well.
