A Relationship between δ13C (annual mean from summer and winter feeding) values in cattle tail hair and the annual dietary proportion of maize (DM). B Relationship of the area under maize [% of total agricultural area per farm] to δ13C values in cattle tail hair (annual mean). Each point refers to one farm (A–Q) and symbols indicate feeding regime. The solid line includes Geestland farms, the dashed circle Peatland farms, and the dotted line Marshland farms. R2 show coefficient of determination and grey bands show 95% confidence interval
