Ash Dieback (Chalara)  

The disease was first confirmed in Britain in 2012.

The disease is from a fungus called Hymenoscyphus fraxineus.

Symptoms – I include leaf loss, crown dieback and bark lesions.

Prognosis – The disease is usually fatal, by weakening a tree to the point it becomes infected with another disease.

Experience in mainland Europe suggests that young trees a quickly killed but older, mature trees a quiet resistant.

Method of Spread – is by wind up to 10 miles, any further would be likely by the transportation of diseased trees, or movement of diseased logs/timber, however this is thought to be of low risk.
