Thread: Beaver Reintroductions

    Beaver Reintroductions

    After reading a recent newspaper article I'm quite interested to hear if anyone in the chosen area has any opinions on whether this is a good idea or not.

    The article threw up some interesting views and I've got to say that at the moment I'm undecided if the pros outweigh the cons.

    The subject does however seem to have attracted the same kind of zealotry as the badger followers display. Here's an extract from the website:

    "There is no doubt in our minds that beaver reintroduction to Scotland will be highly successful and much appreciated by the great bulk of the Scottish people. We believe it is important to be enthusiastic, confident and capable over the project and that it should not become bogged down by doubts and excessive scientific proof."

    Of course, why let a little thing like 'scientific proof' get in the way of a good idea?

    One of the best composed articles I read re beavers was by Leif Brag, wildlife manager for Tilhill Forestry in Argyll.

    KNAPDALE – Proposed Beaver Reintroduction by Leif Brag, Argyll resident
    As a Wildlife manager and lover of all sorts of wildlife and nature it would only be natural of me to welcome the proposed reintroduction of European beavers in Scotland.
    However, as I am convinced that the reintroduction will cause conflicts with other interests, I will have to be against the proposals, as it wouldn’t be right to put beavers through the stress of capture, transport, and radio tagging for the purpose of a trial which surely will cause problems.

    SNH have tried this proposal before and it was, in my mind, rightly turned down. SNH stated in their earlier application, that the beavers would be monitored and that any beavers straying outside the trial area would be recaptured and brought back to the trial area.
    SNH stated that beavers are very easy to trap. This is only true where beavers have established territories and runs, and the focus is on trapping a beaver out of a bigger population. Where beavers are roaming because of the lack of an established territory or because of being displaced by other beavers, it becomes much harder to trap individual beavers.
    The fact that the beaver is known to be in the area, by radio tracking it assuming that the radio tracking works, only makes it marginally easier to trap it, as it could easily have moved on again the next day. In any case, radio transmitters can only be fitted onto the original beavers and not necessarily to their young ones.

    Roy Dennis an independent ecologist has on numerous occasions stated that a forest without beavers is like running a car without oil! – Lets be serious, - Scotland has been running forestry successfully for many years without beavers, however Roy, try to run your car without oil for half an hour.

    SNH has publicly requested that the Deer Commission for Scotland get their act together to control Scotland’s deer herd or they will themselves start to use their powers.
    Yes, - deer cause damage to both commercial and natural woodlands and vegetation but this damage is mostly in the form of browsing, which only reduces the growth rate the trees, whereas the beaver kills every single tree that it is feeding on.
    Each beaver will fell up to 2000 trees per year, in sizes varying from saplings to old mature trees. I have personally, during a trip to Norway, seen several oak trees, approximately 1’ thick, felled by beavers as well as an Aspen, which was 20” in diameter.

    SNH also stated that beavers do not build dams like their American cousins. This has been taken by many to mean that European beavers do not build dams, which is incorrect. The European beavers do build dams, however not quite as big as the American beavers, but still big enough to cause problems. A former local SNH employee admitted that she was surprised to see the size of dams and the problems with the beavers, when she witnessed it for herself on a visit abroad.

    Norwegian forest owners accepted the beavers for a number of years, as most trees felled by beavers are broad-leaved, which were regarded as weeds in the commercial conifer forest. However new markets for oak, birch and aspen changed the perception of the beaver and bounties were paid for killing beavers. The payment of bounties stopped after the Norwegians realised that they could get, especially Danish and German, hunters to pay for the right to shoot beavers. Ordinary people living in areas populated with beavers are still having to protect their ornamental garden trees and fruit trees with steel sheeting to a height of 4-5’, to avoid them being felled by beavers.

    Swedish forest owners are having the same problems as the Norwegians. One report tells of a culvert being dammed by beaver in one knight, resulting in flooding that washed away 100 meters of the road, leading to a repair cost of SKr 600,000.00 (£40,000.00).

    Denmark recently reintroduced the beaver and within one month of the reintroduction one of the beavers had travelled 20 miles and had, in one night, gone in to a garden, where it had felled all the garden owners’ fruit trees and all his Brussels sprouts. Danish authorities denied any liability, as it was a wild animal!

    Germany also reintroduced the beaver and I have personally seen some of the problems in Bavaria, where the beavers have populated drainage canals in an arable area. This has led to farmers having to remove dams on a regular basis to avoid flooding. Additionally the beavers are burrowing in to the banks of the canals, causing the ground to subside when the farmer drives over the burrows with heavy machinery. I have been told that this has led to expensive repairs on at least one combine harvester.
    In Germany, the owner of the hunting rights must pay compensation to farmers and forest owners for any damage caused by animals that can be hunted. This is to ensure that the hunters keep populations under control. In the case of the beaver, the German hunters have said that they do not want an open season for beavers, as they didn’t ask for the reintroduction and they don’t want the beavers to become their problem.

    The idea of the reintroduction is now being aired again, this time by the Scottish Wildlife Trust and the Royal Zoological Society for Scotland; however the only change since the last application is that we now have a different minister in charge.
    It beggars belief that wildlife organisations are so keen to spend vast sums on the reintroduction of beavers, which will be controversial and yet at the same time stand by and watch the decline of the Black grouse, and the spread of the Grey squirrel, without any real intervention other than just monitoring.

    If the reintroduction was to go ahead, will the same bodies pushing for the reintroduction be prepared to pay compensation for any damage caused by the beavers?

    It is not unthinkable that the beavers will find their way into the Crinan Canal, where burrows in the canal bank would be a serious issue. Likewise it is not unthinkable that flood damage akin to the Swedish example above would occur, and the beavers could easily travel further a field and cause damage in some of the wonderful botanical gardens that we have on the West coast of Scotland.

    I do not have much knowledge of beaver fever, but with so much of the West coast Scotland’s drinking water being sourced from surface water, any risk, however slight, must not be allowed.

    We have them about 12 miles from me, and they have been there for a few years and have now started to spread out and are already causing issues I believe.

    Jim. Thanks for posting that - very interesting if a bit heavy on the heresay anecdotes, but I suppose as it was a letter of protest it included them for maximum effect.

    Maybe this should all be headed up as 'Beaver Introductions' as there seems to be considerable evidence to dispute the 'fact' that beavers were ever resident at all in the major parts of Scotland in times gone by.

    Could it be that certain MSPs are promoting this project at all costs because of it's perceived unique 'Scottishness', and therefore something they want to be seen to be associated with?

    With reference to the Guardian article you cite, there is mention of the Gaelic for beaver equating to 'water-dog'. Here may lie evidence that might support the contention that beavers were unknown to the Scottish Gaels and thus absent from the most northerly parts of Britain. The word in question, I presume, is the same as the Irish/Gaelic dobharchu, which equates to the Welsh word dyfrgi which is, in turn and, unequivocally, an otter.

    The Welsh for beaver is afanc whereas an on-line (Irish) Gaelic dictionary offers just beabhar, simply a Gaelic spelling of the English pronunciation. One might conclude, therefore, that whereas beavers existed in mainland Britain recently enough for the Britons to retain a specific name for them, their extinction in Ireland was early enough for the Gaelic name to have been lost. Furthermore, that the Scotae that subsequently invaded the north of Britain failed to form a word of their own would suggest that there were no such creatures in their lands that required such specific reference.

    No wonder, therefore, that emigrant Gaelic speaking Scots in Canada wrote home with stories of 'water-dogs' when referring to beavers. The creatures had clearly been unknown to the Gaels for long enough for them to disappear from their culture such that the closest reference they had was the otter.

    Then again, I might be wrong...

    If nothing more, at least this surely entitles any true Welshman to claim, 'Rwy'n caru afanc!'
