More grazing, more damage? : Assessed yield loss on agricultural grassland relates nonlinearly to goose grazing pressure
1. In recent decades, conflict between geese and agriculture has increased. Management practices to limit this conflict include concentrating geese in protected areas, derogation shooting or population reduction. To justify such management, we need to understand their effects on goose-related damage...
