ANOTHER case of ash dieback has been discovered in the UK.

The tree disease, already confirmed in Northumberland, has been found in woodland in East Sussex, bringing the number of English counties where the disease has been found to 11.

Defra said ash dieback has been found at a total of 237 sites including 127 locations in the wider environment. It is now believed the disease has been in the UK for at least two years but has only recently been discovered following intensive checks.

The Chalara fraxinea fungus, which causes leaf loss and crown dieback and can lead to tree death in ash trees, has wiped out 90% of ash trees in some parts of Denmark and is becoming widespread throughout central Europe.

Martin Ward, chief plant health officer, said: “Although the rate at which we are discovering new areas infected with Chalara is slowing, there are still results coming through from our surveying exercise earlier this month and reports from landowners and the public.

“The better informed we are, the more effective we can be in our work to contain the spread and impact of this disease.”

The disease, which has hit a high proportion of ash trees in northern Europe, was confirmed in the UK at a tree nursery in March.
