Northern tufty-botherers in scientific dust-up

Red squirrels, the little furry darlings – they need our help! Yes, if about fifty million column-inches are to be believed then we can all join in to help fight the introduction of grey squirrels and the decline of the native red. It’s suggested that by keeping the grey terror at bay in the north of England maybe we English can keep a population of our red friends. A great deal of money and effort has been spent on trying to do just that. At the same time money for other species conservation efforts has come under increasing pressure, so perhaps it’s not a bad thing that Natural England have published a report from some heavyweight scientists to see if the resources expended on red squirrel conservation in northern England have been well-used. The results make uncomfortable reading.

Whilst it’s not all bad news, it seems that not everything is going very well – and the problem isn’t just the grey squirrels but also the people. The report has some rather blunt suggestions, and some people are not going to like it. Continue reading

Invisible squirrels

Once more the allegedly deadly grey squirrel rears its cute little head in the media, with a rather desperate article in the Telegraph trying to make an old story sound fresh:

Teams in Britain and America are working against the clock to develop a method of rendering the pests infertile using treated bait… The contraceptive would work by attacking the immune system of the squirrel, suppressing its fertility. Scientists are desperate to find ways of tackling the grey squirrel threat before it causes more damage to the red population…

A crazed squirrel
The unstoppable advance of the crazed grey invaders…?

It’s an interesting idea but very far from a new one. It’s also not got much prospect of any immediate success. In 1998 Hansard reported:

Lord Inglewood referred to the Forestry Commission investigating the potential of immuno-sterilization of grey squirrels… But it may be a long-term solution. Success is far from guaranteed at this stage.

It seems that little has changed in ten years. Still, at least the Telegraph is aware of the distribution of red squirrels, reporting accurately enough that they “are now only found in the Isle of Wight, Brownsea Island, western Wales, northern England and parts of Scotland“. The Guardian, by contrast, in its charmingly-illustrated but badly researched photo essay on red squirrels manages to suggest that “they live mainly in pine forests in Scotland, but can be spotted in the North of Enlgand(sic), west Wales and on Brownsea Island.” So none on the Isle of Wight then? Once more the only stable and sustainable population of reds in the UK is overlooked. Grrr!

Twirl-a-squirrel

Of little interest to The Ranger, safe on his Island fastness with no grey squirrels (and plenty of red ones), this American invention will no doubt be much in demand when it is introduced in the UK.

The manufacturer’s website claims:

Hilariously funny! Amazingly effective! Squirrel’s weight on feeder activates a motor which gently twirls him off!

Needless to say, the weight of the little birdies does not have the same effect. And it is rather funny. The video illustrates it very well – with the added “attraction” of some cod Beach Boys harmonies. And if you want to buy one, don’t ask The Ranger. He doesn’t have any. Ask the makers.

Death to Grey Squirrels…? Website down permanently

Update 16 January 2006: it seems that the website is gone for ever, after its owner made some sort of truce with the squirrels. How queer! Original article begins: They’re cuddly! They’re cute! They see off red squirrels in droves and eat all your nuts. And apparently, all your crocus bulbs. One enterprising Londoner has had enough of the ravages of the grey squirrel so has established www.deathtogreysquirrels.com, where keen squirrel-nobblers can swap tales of serial squirrelicide and back-garden buckshot mayhem. What’s more, there’s plenty of advice and ideas on offer on how to see off the little pests, with little consideration for their welfare – indeed, quite the contrary.

The Grey Squirrel
Now, the Ranger sees some positive sides to this campaign. Certainly getting rid of grey squirrels is a good idea, because of their effect on the red squirrel and on woodland in general. It’s also quite refreshing to see someone willing to be frank about what they want to achieve, and how, without being hamstrung by the meeting the concerns of animal welfare. Indeed, the webmaster actually says: We bet you’ll soon meet plenty of old ladies who love their squirrels. Don’t let them stand in your way! Very robust. Perhaps it’s no surprise that the author remains anonymous. But (and you could feel that ‘but’ coming, couldn’t you) the Ranger also asserts that there are some problems with this entertaining approach to species conservation. The most significant one is that it will be utterly ineffectual, except, perhaps in allowing the participants to express their ire against the grey invader. A 2003 study reviewing statistics over about 10 years across the UK by the European Squirrel Initiative says:

In none of the estates illustrated here or in many others does any form of squirrel control provide an acceptable reduction in damage either because the control proves too costly or it is unsuccessful… At no time or place is it possible to eradicate the grey squirrel completely with the present mechanisms for control due to the persistent endemic spread and replacement of the animal.

Grey squirrel populations are so robust that even the most vigorous culls are unlikely to have anything more than a very local effect, and even then, only temporarily – unless a really big population can be wiped out over a significant range, and there’s no known way to do that at present. In case you’re really on the ball, this objection also applies to some extent to the red squirrel reserves maintained in the North by culling greys. A second objection goes to the very essence of the idea. It’s time to remember those old ladies mentioned above. Are they wrong to cherish the little grey fellows? Well, yes they are, but it’s not as simple as that. There’s no doubt the the grey squirrel in a suburban garden can be a charming creature which gives many people pleasure, and an accessible interaction with the natural world. Never mind that it’s not natural. That dosn’t matter in this context. From this care for squirrels and similarly birds, many go on to support charities such as the Wildlife Trusts or, particularly, the RSPB. Some even become involved in the running of such bodies. Anyone who has worked for a wildlife trust will know the truth of this – the lover of the cuddly mammal or chirpy garden bird is an overwhelmingly powerful lobby. And on the backs of these ecological titans rides the political will and financial means for much good work to be done.

The Red Squirrel
On the Isle of Wight in 2004 somebody was convicted and fined after threatening to release grey squirrels on the grey-free Island. The circumstances of that case were bizarre but there are certainly those who are so keen on the greys that they will quite deliberately introduce them. Whilst this sort of enthusiasm exists, any eradication programme can only ever be a precarious one. So does the Ranger suggest that the grey squirrel be conserved for fear of having to lay off National Trust wardens? Far from it. I’m still firmly of the view that the grey should go. However, that simply cannot be done at present. If the means ever does become available, it should be a very carefully implemented project, over the entire country, and one which involves people as much as pest control. This will take decades. To eradicate the greys in part, only to let them return later, would be useless. To wipe out the invader without any provision for the return of the shyer red squirrel would be equally counter-productive – for who would support a campaign to replace their furry grey friends with nothing? To alienate those who love squirrels would be a spectacular own goal, and would ultimately be self defeating. Conservation is not just about species – or rather, it is, but only if we allow ourselves to be one of those species. We are a part of nature and our own interactions with it are ignored at our peril. This simple debate about eliminating a perceived invader is far more complex than it appears to in the waggish www.deathtogreysquirrels.com – to whom the Ranger wishes the very best of British. The human involvement in the grey is complex, and only in a programme in which this too is addressed will there ever be a real chance to eradicate the grey squirrel. See also
