Yorkshire Dales ‘could have too many hen harriers before long’

Clive Aslet is a former Editor of Country Life magazine who boasts of being ‘an acknowledged leading authority on Britain and its way of life‘, whatever that means.

One thing’s for sure, Mr Aslet is no leading authority on the principles of ecology.

He wrote a bizarre comment piece for The Times, published last week in response to DEFRA’s new (not new) raptor persecution maps, as follows:

BIRDS OF PREY NEED PROTECTION FROM HUMAN PREDATORS

The protection of raptors, such as hawks, eagles, buzzards and falcons, is one of the great success stories of the British countryside. When JA Baker wrote his classic The Peregrine fifty years ago, many species were in long-term decline, thanks largely to insecticides used in intensive agriculture and the severe winters of the early 1960s. Numbers have risen sharply since DTT and its like were banned, and raptors were given legal protection. Peregrines now even nest on London skyscrapers.

There have been successful reintroductions, such as that of the red kite: it’s common to see a dozen of these enormous birds now circling over the M40 in Oxfordshire. But successes like these worry country people who know that having too many large carnivores at the top of the food chain means that other species will suffer. Red kites are scavengers (hence their preference for roads, which provide a ready supply of carcasses) but when carrion becomes scarce they turn to living prey.

Grouse moors are a special problem. For the moor owner, grouse are a valuable crop. The bird provides a livelihood to the keepers who control predators such as foxes, stoats and rats that prey on eggs and chicks. Vermin control also allows wading birds like plovers, lapwings and curlews to nest in safety: it’s a wonderful thing to visit a moor teeming with wading birds as well as grouse, whether or not you plan to shoot any of them. But as a report published today shows, many keepers trap or kill hen harriers and sparrow hawks that threaten the viability of the shoot. They deserve to be prosecuted.

At last, landowners are getting the message that this behaviour is unacceptable, and are making greater efforts to conserve raptors. The prospect of the law in Scotland, which targets landowners as well as keepers, being introduced in England has concentrated minds. As has the possibility of a Labour government banning shooting altogether and making grouse moors worthless.

But there remains, as in many areas of conservation, a geographical imbalance. Some areas have too many raptors, others none at all. Exmoor, for example, has no hen harriers; before long, given the male bird’s promiscuity, the Yorkshire Dales could have too many.

Relocating broods from overpopulated areas to underpopulated ones is the answer — opposed, sadly, by the RSPB. Brexit offers a way out of this problem. Freed from the need for a one-size-fits-all approach, we can create the flexible conservation policy our birds of prey deserve.

ENDS

Leaving aside his obvious failure to grasp the simple conventions of predator/prey relationships (we can’t be bothered to turn this in to a lesson on the basics of ecology), we wanted to focus on just the last three paragraphs of his article.

Aslet seems to be muddled about brood meddling. He argues that “Relocating broods from overpopulated areas to underpopulated ones is the answer“. But that’s not what DEFRA’s hen harrier brood meddling is about. It might well be what the grouse shooting industry thought it was about, and wanted it to be about, when they first signed up for it – ‘Yeah, great, let’s get rid of hen harriers from our grouse moors and ship them off down to southern England so they can’t interfere with our shooting days in the northern uplands’, but as we now know, any hen harrier chicks removed from grouse moors and raised in captivity as part of DEFRA’s absurd brood meddling plan, will HAVE to be released back in to the uplands close to where they were first removed, and their release will coincide with the start of the grouse-shooting season. They cannot be used as the source birds for DEFRA’s equally absurd southern England reintroduction plan.

As for Aslet’s claim that “before long, given the male bird’s promiscuity, the Yorkshire Dales could have too many” [hen harriers], chance would be a fine thing! According to this report, there were only three successful hen harrier breeding attempts in the Yorkshire Dales National Park between 2000-2007, and since then, there haven’t been any!

Aslet also claims, “At last, landowners are getting the message that this behaviour is unacceptable, and are making greater efforts to conserve raptors“. Really? Some landowners are, for sure, but how many of those landowners manage driven grouse moors? It’s all very well saying that raptor persecution is unacceptable and pretending to be on board, but the proof, as they say, is in the pudding. There were only three successful hen harrier breeding attempts in the whole of England this year, and for the second year in a row, not one of those was on a driven grouse moor.
