Buried ponds to be excavated in Norfolk to revive wildlife

Rare species set to return to pingos', which are basin forged by ice age and then buried to give way to farmland

Ghost pingos, unique ponds forged by the ice age and buried during the era of industrial agriculture, are to be excavated to revive wildlife on two former farms.

Rare species including the scarce emerald damselfly and the northern pool frog are set to return to the pingos, which are being restored on farmland next to Thompson Common near Thetford in Norfolk, a little-known nature reserve whose 400 ancient ponds make it the pingo capital of Britain.
