Conservationists build 400-tonne structure to tempt migrating birds back to nature reserve after 25 years
A giant “sandcastle” has been constructed to encourage sand martins to nest at a nature reserve for the first time in 25 years, Surrey Wildlife Trust has said.
The 400-tonne sand installation at Spynes Mere, near Merstham, Surrey, was built by professional sand sculptors who used a “giant bucket mould” made from wooden boards, as well as the help of diggers and dumper trucks.
