The aim of this study is to provide insight into the additional costs of biodiversity measures for dairyfarms and arable farms on the basis of an integral better score on indicators from the biodiversitymonitor. The costs for intensive dairy farms, extensive dairy farms and farms on peat are € 1.95,€ 2.18 and € 3.08 per 100 kg of milk respectively. Weighted over the three types of farms in the dairyfarming sector, the additional costs are € 2.21 per 100 kg of milk and € 417 per hectare. Theestimated additional costs for arable farms on clay with a cultivation plan with potatoes forconsumption or on sand with a cultivation plan with potatoes for starch are 324 and 185 per hectarerespectively. Both dairy farming and arable farming require a wide range of measures to achieve abetter score.
