Landmark report reveals the impact of gamebird releasing

With millions of pheasants and partridges released into the countryside each year, what impact are they having? That’s the question answered in a landmark report from leading conservation charity the Game & Wildlife Conservation Trust (GWCT).

Using over 140 scientific papers and reports as the basis for its findings, the report studies the ecological consequences of released birds and their management on a range of factors – from hedgerows and lichens to invertebrates and songbirds. The 52-page report is freely available to read at


As the most common quarry in the UK, pheasants are synonymous with shooting and, for much of the public, that’s where the interest ends. For others, however, the debate on releasing pheasants and partridges for shooting has gained exposure in the past few years.


The authors, Dr Rufus Sage and Dr Roger Draycott, highlight how studies show management for these popular gamebirds can help songbird numbers, supports the planting of hedgerows and can help butterflies and bees to thrive on woodland edges, but also highlight the potential for negative impacts such as disease and damage to soil and invertebrates within release pens and how these can be reduced by following best practice guidelines.


Roger Draycott, Director of Advisory and Education at the GWCT, is hopeful that the report will prompt an open and balanced discussion on releasing and what those involved can do to make more of their efforts. “Most positive effects, such as the provision of winter food and cover for songbirds, are a consequence of gamebird management activities”, he notes, “while any negative effects such as an impact on ground flora are caused by the released birds themselves. Importantly, many of some of these negative effects have relatively straightforward management solutions.”


The field-based research work referenced in the report was undertaken at many hundreds of different release-based shoots over several decades and provides a broad overview of what is happening across the UK countryside.


Those looking to improve biodiversity on their shoot are urged to follow the GWCT’s Principles of Sustainable Gamebird Management. These 12 principles were put together in September 2020 after consultation with hundreds of GWCT members, shoot managers and after careful review of internationally agreed guidelines on sustainable use and biodiversity.

James Swyer, Press & Publications Manager at the GWCT, comments that “as providers of research and a leading voice in game management, the GWCT is central not only to this debate, but also in understanding what is happening on the ground and improving standards. Participants in shooting should be discerning about where they buy their shooting, and all shoots are encouraged to follow our principles. The overall balance of effects in future will depend on how well best practice is adhered to.”
