On the coast of South Wales the conservation group Plantlife has decided to take drastic action. A fleet of bulldozers has appeared at Kenfig Sands, home of the rare fen orchid. The plan is to reconstruct this massive dune system, giving space for the natural processes of wind and wave to mould the landscape, returning the natural mobility that so many of our dune species need.
Is Mother Nature being given a much-needed helping hand or should we leave what remains of our dunes well alone? Tom Heap reports from the Welsh coast.
