The news
that the government plans to remove the first colony of wild beavers seen in
England for 500 years has caused huge controversy.
The
Department for Environment, Food and Rural Affairs (Defra) is believed to be worried
about the impacts and consequences of beavers living on the River Otter in
Devon.
It is
reported that Defra plans to capture and rehome the beavers in a zoo or
wildlife park - while a petition has been set up urging the government to leave
the animals alone.
The small
beaver colony, discovered earlier this year, is thought to be the first of its
kind in England for around 500 years.
Until then
beavers would have been a common sight along the country's rivers - which has led many environmentalists and
conservationists to call for their reintroduction to our waterways.
Such a
reintroduction, if one is ever given the greenlight, is likely to involve very
small numbers of beavers on targeted river sections.
Parachuting beavers...
However,
the translocation of beavers has not always
been conducted in such a sedate manner.
Indeed in
the 1940s beavers were actually parachuted into areas of America: literally,
strapped to parachutes and thrown out of aeroplanes!
One of those
involved in the parachuting-rodent scheme even wrote a scientific
paper on the subject, which has to be one of the most unusual papers I've ever
read.
Published
in the Journal of Wildlife Management in 1950, Elmo Herter from the Idaho Fish
and Game Department wrote the article 'Transplanting Beavers by Airplane and Parachute'.
In it he
describes the need to 'transplant' beavers from where they 'exist in abundance'
and may be causing damage, to areas where they're not found and could set up
'fur-bearing populations'.
According
to Herter's paper such practise was relatively common but involved an 'arduous,
prolonged, expensive' schedule involving several days journey with trucks and pack
horses.
Many
beavers died en route and some of those that survived became 'dangerously belligerent'.
So a
better method was developed which involved planes and ex-military parachutes.
The paper goes into fabulous detail for the design of a box which beavers could be
kept in during their flight and skydive.
Once on
the ground the specially constructed box sprang open to allow the, surely bewildered,
beavers to leave and set up their new colony.
To get to this
final working design though the team had to test out several different types,
using dummy weights, and, of course, real beavers.
Perhaps
the finest part of the paper describes the adventures of one such test-beaver:
One old male beaver, whom we fondly named 'Geronimo', was dropped again and again on the flying field. Each time he scrambled out of the box, someone was on hand to pick him up. Poor fellow! He finally became resigned, and as soon as we approached him, would crawl back into his box ready to go aloft again.
Unfortunately
not all beavers faired so well:
One beaver worked his head through the small opening thus made for him, and managed to climb out onto the top of the box. Even so, had he stayed where he was, all would have gone well; but for some inexplicable reason, when the box was within 75 feet of the ground, he jumped or fell from the box.
Perhaps
the 'inexplicable reason' was that the poor beaver was a little perplexed as to the turn of events which saw it floating
down a river eating a nice piece of willow one minute, and the next being hurled out a large aircraft.
As for
Geronimo, fear not:
You may be sure that 'Geronimo' had a priority reservation on the first ship into the hinterland, and that the three young females went with him.
Crucially
the whole - wonderfully barmy - scheme appears to have been a success, as Herter
reports that 12 months after the airborne beaver-invasion of remote Idaho all
the beavers were thriving.
Apart from
the one that jumped out of its box.
Beavers in the UK...
So instead
of the UK Government getting rid of our beavers perhaps we should be
parachuting more of them into our landscape?
There may not be much call for their 'fur-bearing' properties anymore, but it's possible beavers could help with river and wetland restoration, flood alleviation and
carbon storage.
