Diseased Ash trees
In February 2012, a consignment of infected trees arrived from the Netherlands to a nursery in Buckinghamshire. Since then diseased trees have been found in a number of locations across the country.
Chalara dieback of ash is a serious disease of ash trees caused by a fungus. The disease causes leaf loss and crown dieback in affected trees and usually leads the tree dying.
