The long-running row over Britain’s hen harriers could offer lessons for other conservation conflicts, new research by Cornish academics shows.

Hen harriers’ prey includes birds that are shot for sport, especially red grouse, leading to conflict between shooting organisations and birds-of-prey conservation groups.

The new study analyses almost three decades of UK newspaper articles to see how the debate has evolved.

It finds a peak of “polarisation” after the launch in 2016 of a government-backed action plan for the recovery of hen harrier populations.

“Our research offers a variety of options that could help with other conservation conflicts,” said Filippo Marino, of the Centre for Ecology and Conservation on Exeter’s Penryn campus in Cornwall.

“We identified the most polarising issues in the debate, and other areas where there was broad agreement. It’s useful for opponents to be aware that they share some common ground, and to understand their key areas of disagreement.

“Our findings also show that the hen harriers debate has been dominated by a few high-profile people and organisations. This has probably perpetuated the conflict, increased polarisation and hindered resolutions.

“Allowing new voices to speak might change the dynamics and help unlock this entrenched debate.”

Researchers examined 737 statements in 131 newspaper articles published from August 1993 to December 2019, finding three main themes in the debate: problems, solutions and reactions.

They found that a multitude of people and organisations contributed to the hen harrier debate. However, only a subset was regularly quoted.

“Despite a long history of conservation measures and the recent decline of territorial pairs of harriers in Great Britain, the hen harrier conflict appears to have worsened and become more polarised both in England and Scotland,” Marino said.

“A key point of conflict is a relocation scheme, known as brood management, that moves hen harriers away from grouse moors. Meanwhile, reintroduction of hen harriers in southern England – where numbers are lower compared to northern England and Scotland – have been less polarising.”
