A NEW study has uncovered “compelling evidence” of the illegal killing of protected birds on grouse moors, it is claimed.
This is based on 10 years’ worth of data centred around hen harriers in the north of England. Many of the raptors had a range which took them into southern Scotland.
Aberdeen University, working with colleagues at South Africa’s University of Cape Town, analysed records produced by satellite tags on almost 60 birds.
They found the chances of hen harriers dying or disappearing over areas predominantly covered by grouse moor was 10 times higher than areas without the sporting estates.
More than 70% of tagged harriers were either confirmed or considered very likely to have been illegally killed.
Speaking to The National, Professor Steve Redpath, who is chair in conservation science at Aberdeen University, said: “We found the tags were suddenly failing on grouse moors at a much higher rate than expected by chance. We can’t think of an alternative explanation.
“What do we do about it? It’s not an easy thing to answer. There clearly needs to be change.”
Last week, Labour MSP Claudia Beamish said wildlife crime was “intractable” in the South Scotland region she represents.
Holyrood’s Environment, Climate Change and Land Reform Committee heard the 96% conviction rate is the highest in seven years, but some incidents of poisoning against birds of prey are not recorded as crimes due to difficulties in proving their deaths were intentional.
MSPs raised concerns about the disappearances of three hen harriers and six golden eagles, and David Green, of the Procurator Fiscal Service, told a meeting of the committee that evidence gathering “is a problem” for investigators. He said: “You can find that you’ve got raptors that have been poisoned, but were they poisoned where they were found or potentially many miles away?”
On what the study data means for Scotland, which has higher numbers of hen harriers than England, Redpath said: “We can’t say very much about Scotland. It’s probably a reflection of insensitive grouse moor management. We would have to repeat this in the Highlands to see if these findings apply.”
He went on: “These findings increase the pressure on grouse moor managers, conservation organisations and government agencies to find a solution that ends this illegal activity.”
Welcoming the report, published in Nature Communications, Stephen Murphy of Natural England called it a “significant step in understanding the fate of tagged hen harriers”.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
