Chalara Ash Dieback - Tree Fungal Disease - Important Information


Ash dieback, also known as Chalara dieback, is caused by the fungus Chalara Fraxinea.

In October 2012, Fera scientists confirmed a small number of cases in East Anglia in ash trees which do not appear to have any association with recently supplied nursery stock.

C. fraxinea is being treated as a quarantine pest under national emergency measures, and it is important that suspected cases of the disease are reported.
