Ganzen en ganzenschade in Nederland: Overzicht van kennis en kennishiaten voor effectief beleid

This report summarises all available information regarding trends in goose numbers, phenology and breeding success in The Netherlands and the development of crop damages; and puts these in an international context. Besides, for the first time a national overview of the number of geese that is killed under derogation is presented on the level of the 12 provinces, which are responsible for goose management. Also goose numbers and developments in damage are analysed for the province of Friesland, along with a more general review about the aspects that may confound comparison of goose numbers and crop damage statistics. The results presented in this report serve as input for a national advisory committee, which has been installed to advise the provinces on their management policies regarding conflicts caused by breeding and wintering geese.
