This is likely to prevent any spore dispersal. Read our plan. Chalara ash dieback is present in most parts of the United Kingdom. Ash dieback is a highly destructive disease of ash trees (Fraxinus species), especially the United Kingdom's native ash species, common ash (Fraxinus excelsior). The leaflet provides an introduction to the disease, summarises current advice, and signposts to more detailed guidance produced by Defra, the Forestry Commission and others.

Why the spread of Ash Dieback continues to gain momentum, Ash Dieback: Better news for European ash trees, New hope for trees affected by ash dieback. 1.1 Introduction Chalara fraxinea, known as ash dieback disease, is a relatively newly described fungal disease of ash which was first named in 2006 although dieback symptoms in ash had been first noted in Poland in the early 1990s. These often have a characteristic elongated-diamond shape (pictured above) centred on the joints between branches, or where branches join the trunk. Their assessment concluded that: The best hope for the long-term future of the UK's ash trees lies in identifying the genetic factors which enable some ash trees to tolerate or resist infection, and using these to breed new generations of tolerant ash trees for the future. However, such treatments often have to be re-applied periodically, perhaps every year, and can therefore be expensive. We know that is one pathway by which it entered the UK, because besides the consignment to the Buckinghamshire nursery, we and the forestry and plant health authorities were able to link a number of outbreaks around the UK to nearby recent plantings of imported ash plants. There is no known cure, although some fungicides might be effective in suppressing the disease, enabling individual ash trees of particular value to be saved. If any of these seedlings prove to be tolerant, it’s likely that the mother trees from which the seed were collected are also tolerant. Many Dioceses leave it up to individual churches on whether to use herbicides etc. Read more. However, every one of them will be assessed, and for each report we will: Local spread of up to tens of miles can be caused by the wind blowing spores of the fungus. As part of this work, we are leading a mass screening trial to identify inherent tolerance or resistance in ash trees. If composting the leaves, cover them with with a 10cm (4-inch) layer of soil or a 15-30cm (6-12 inches) layer of other plant material, and leave the heap undisturbed for a year (other than covering it with more material).
