Ash Dieback

Ash dieback is a highly destructive disease of ash trees (Fraxinus species), especially the United Kingdom’s native ash species, common ash (Fraxinus excelsior). It is caused by a fungus named Hymenoscyphus fraxineus (H. fraxineus), which is of eastern Asian origin. 

The disease is also known as ‘chalara’, ash dieback, and chalara dieback of ash. Calling it ‘chalara’ ash dieback helps to distinguish it from dieback on ash trees caused by other agents.

We have been assessing ash dieback disease for north and mid- Wales trunk road agency as part of their management initiative for ash die back. 

We are therefore competent in assessing your trees for ash dieback disease particularly where they pose a threat to the highway or third-party land. 

Private landowners are responsible for all the trees on their land. This includes the felling and removal of dead or diseased trees affected by ash dieback.
