Chalara Ash Disease
Widespread media coverage of this disease, which kills ash trees, is leading to an increased public awareness of the problem and the Council are receiving enquires from members of the public .
A rapid survey of woodlands in Great Britain and Northern Ireland was carried out last week and more sites have been identified. You can find the detailed guidance, and a summary of the key scientific facts of this at
The Institute of Chartered Foresters has produced a short video that demonstrates how to identify the disease, which, while it coincides with the onset of Autumn, is nonetheless distinct from normal Autumn foliage die back.
Updates from the scientific community suggest there are reasons to remain optimistic about the UK ash tree population in the face of this disease. It seems unlikely to be comparable to the elm disease 'pandemic' of forty years ago because the ash trees possess much greater genetic diversity than elms and therefore are likely to be less susceptible to disease. In addition, the spores rely upon wind dispersal during Spring and Summer, which should limit their mobility, whereas elm disease is carried by the elm beetle, which has a greater range.
Don't panic, and don't be tempted to fell your ash tree! It may contain the genes that will form resistant trees of the future...
