Hen harrier trial finishes

The experimental hen harrier ‘brood management’ trial that was intended to boost numbers and reduce human-animal conflict has come to a close.

Between 2019 and 2023, 15 hen harrier broods were taken from the wild, reared in captivity and then released once fledged, often with satellite tags.

The trial, which was conducted by a partnership including the Moorland Association, the Game and Wildlife Conservation Trust, and Natural England, concluded that it’s activities had contributed to increased numbers of nesting hen harriers on some grouse moors.

By showing that the predation of grouse by nesting hen harriers could be legally managed at levels compatible with grouse shooting, the study also hoped to change attitudes and reduce illegal raptor killings. 

A GWCT spokesperson said: “The hen harrier brood management trial shows overall positive results and is a good example of a proactive approach in seeking to resolve a human/wildlife conflict. 

“The fact that the illegal killing of hen harriers has been associated with grouse moor management was the reason why the Hen Harrier Action Plan was created in the first place.

“The conclusion shows that progress can be made in reaching a solution to a complex, polarised and multi-layered conflict.
