The purpose of this survey is to investigate how wintering birds and Brown Hare benefit from using Agri-environment scheme (AES) options in winter, which remains a major gap in our knowledge. This work will complement existing studies that have successfully evaluated the effects of AES options on farmland birds and will further our understanding of why the majority of breeding farmland birds are still in decline.
