Danish scurvy grass thrives in gritted road conditions
A Welsh botanist tells how a plant is thriving thanks to the salt put down across the country to help drivers in icy conditions.
Danish scurvy grass has become the fastest moving plant in Britain and the road transport network is becoming a highway for its spread.
Dr Trevor Dines, from Caernarfon, who is conservation manager from Plantlife Cymru, will explain more about the plant on the Channel 4 programme Wild Things at 2030 GMT on Monday.
He spoke to Peter Johnson on BBC Radio Wales.
