Hen Harrier - Problems in The United Kingdom

Problems in The United Kingdom

In the UK, the Hen Harrier suffers illegal persecution by gamekeepers and their employers on shooting estates, particularly those managed for Red Grouse shooting, resulting in local and regional extinction in many areas, particularly in England where only 4 breeding pairs survive despite abundant suitable habitat capable of holding several hundred pairs. Because of this they are now very rare in many parts of the UK, and under threat in many more areas.

This problem received a high profile in October 2007 when police investigating the killing of two Hen Harriers on the Queen's estate at Sandringham in Norfolk interviewed Prince Harry and a friend during their investigation. No charges were brought as police were unable to obtain sufficient evidence to prosecute.

Since the assumed threat to Red Grouse is the main reason for the persecution of this species in the UK, a project funded by Scottish Natural Heritage, the Game & Wildlife Conservation Trust, the RSPB and Natural England was launched at Langholm Moor in Scotland from 2007. The Langholm Moor Demonstration Project (LMDP), a 10-year investigation, costing £3 million, is intended to see whether grouse and raptors can live side-by-side harmoniously.

A similar project, the Joint Raptor Study (also referred to as the 'JRS' or 'the Langholm Study') was run on Langholm from 1992 to 1997. The study made many findings and a host of peer reviewed papers were published on the work, in addition to the final report. Among the most often quoted findings were that long term declines in red grouse populations were "extremely unlikely" to be due to raptor predation and were attributed to habitat degradation/loss, and that raptor predation was the most likely explanation for the failure of grouse stocks to recover at Langholm once the population had fallen to a low level. The project ended in 1997, although a follow up supplementary feeding trial was run by the same team in 1998 and 1999. Grouse shooting on the moor was abandoned for the 1998 season onwards.
