At the current population sizes, the practice of scaring geese off pastures in the province of Friesland probably ends up costing more than it saves. Ecologist Monique de Jager and colleagues from the Netherlands Institute of Ecology (NIOO-KNAW), Utrecht University, Wageningen University & Research and the University of Amsterdam conclude this based on a model study, that was conducted as part of the Dutch contribution to European goose management. The results suggest that scaring geese is cost-effective only when there are few geese in the area.
