Ash dieback

Affected Ash

Leaves on an infected tree often suffer from wilting and black or brown discolouration. In severe cases, the entire crown may succumb to the disease, with shoots twigs and branches dying back

Chalara dieback of ash is a serious disease of ash trees caused by a fungus called Chalara fraxinea (C. fraxinea). The disease causes leaf loss and crown dieback in affected trees, and it can lead to tree death.
