Fig 5: Once the fungal infection spreads fully across a stem or branch, nutrition is cut off beyond that point and leaves begin to wilt and die. Distorted and flattened apical bud on epicormic growth caused by infection with Hymenoscyphus fraxineus, Ash Dieback fungal disease, Wales, UK. A tree which has been felled due to disease. The symptoms include wilting leaves and brown dying leaves. The prognosis isn't pretty, but then you will have gathered that already from media coverage of ash tree dieback. This section presents a gallery of the Chalara fraxinea fungus and trees infected by it.

Some ash trees can be naturally resistant to the disease, even of the same species and variety that are succumbing to the infection, as the image below shows: The UK's task in the coming months and years is twofold: first, to do all we can to sensibly limit the spread of the disease (sensibly being the operative word – a mad rush to deforest ash could remove genetically resistant trees); and second, to ensure that we understand and manage the ongoing genetic diversity of the surviving trees.
