Ash dieback

Ash dieback (ADB) is a disease caused by the fungus Hymenoscyphus fraxineus, (formerly known as Chalara).  Once an ash tree is infected the disease restricts the flow of water and nutrients leading to rapid decline and ultimately death. ADB is now widespread across the UK. Current estimates suggest that ADB is likely to lead to the loss of 95% of the ash trees over the next 5-10 years. 

Work has already begun to identify and manage the risk associated with ADB and this work will continue as part of the council's ongoing risk management approach for trees.  Ash trees with the disease will need to be carefully managed and where felling is required for safety reasons, an appropriate replanting strategy will be adopted on a case by case basis.
