Ash Dieback, 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 usually leads to tree death.
We would fully encourage you to consider implementing biosecurity measures to your operational plans if you have not already done so. Please click here to find out more http://www.forestry.gov.uk/pdf/FCMS028-guidance.pdf/$FILE/FCMS028-guidance.pdf
Guidance is available on the Forestry Commission website. Anyone involved in the management of woodlands should carry out their own risk assessment based on individual/site circumstances e.g. forestry & arboricultural sector workers should employ more stringent biosecurity procedures to prevent the risk of spread between sites.
Please be on the look out for Ash Dieback in your area and for a reference of symptoms visit www. http://www.forestry.gov.uk/chalara . This website is updated regularly.
