What is Ash Dieback and how to spot it
Ash Dieback is a fungal disease that kills all ages of ash trees, causing leaf loss and crown dieback leading to death. Common Ash, is the third most prevalent species of Britain’s woodlands and present in high numbers throughout the City’s 504 hectares of woodland and along with other varieties have a significant presence in our local parks and open spaces. The disease is being treated as a highly serious issue by the Forestry Commission under national emergency measures and all suspected cases must be reported.
The symptoms are visible as wilting and dark discoloration on the leaves. Shoots and branches of affected trees may also show lesions under which the wood may also show discoloration. In severe cases, the entire crown showing leaf loss and substantial dieback is characteristic. Now that it's autumn, people should look for the characteristic lesions or die back rather than for leaf symptoms.
More information on how to spot Ash Dieback and report it is available from the Forestry Commission http://www.forestry.gov.uk/chalara and there is also a free app available http://ashtag.org which can help identify the disease.
The Arboricultural Service consists of specialised officers known as Arboriculturists. They are responsible for the management of thousands of trees in our parks and open spaces, over 12,000 street trees across the city and they assist with the management of over 500 hectares of woodland in and around Brighton & Hove.
