Woodland owners are being urged not to panic this evening as a disease that has badly affected Ash trees across Europe, has now spread to the West Country.
There have been more than 15 cases of Ash Dieback identified here, but this is the first time an infected tree from a nursery has passed it on to an existing ash tree.
Efforts are now being made to try to stop the infection spreading further.
