Interactive Excel data sheets to analyse potential interventions (i.e. changes in land use type and intensity) in the Dutch dairy production system towards conserving biodiversity. The tool uses the Dutch dairy sector as a case study and represents the current land use by dairy farmers in the Netherlands. The measures applied result in different landscapes that satisfy different biodiversity targets. At the same time, the tool measures the (negative) impact on food production. This interactive Excel tool is a supplement to: Kok A., Ripoll Bosch R., de Olde E.M., Muscat A., de Boer I.J.M.
