This document discusses what archaeological sites are and why they are important. Managing archaeological sites on cultivated land however presents a particular challenge, since regular cultivation – or only one instance of deeper ploughing – can damage or destroy any hidden remains. Farmers can play a vital role in ensuring that these sites are passed down to future generations, and the leaflet discusses how they can find out more about sites on their holdings, why cultivation can be damaging, how to recognise and minimise damage and the grant-aid available for improving the management of monuments.
