Ashes to Ashes

Recommend listening to the Radio 4 documentary 'Ashes to Ashes'. A year on from the discovery of the fungus Adam Hart investigates how quickly Ash dieback has spread across the country. Scientists are now sequencing the genomes of Ash and Chalara fraxinea - the fungus that is causing Ash dieback - in an effort to find why some trees are not dying from the disease. He also learns of another threat to our Ash trees - the emerald ash borer - which is currently found west of Moscow and is heading towards us. He discovers this pest has already infested Ash in North America and has left a trail of destruction behind it. Link to BBC Listen Again iPlayer: http://www.bbc.co.uk/programmes/b03bg4vh
