The UK has destroyed 100,000 ash trees in a bid to prevent the spread of a deadly disease. The Chalara fraxinea fungus can grow out of fallen leaves and stems of ash trees (Fraxinus excelsior). Wind then carries the spores of the fungus onto other ash tree leaves. Symptoms of dieback include leaf loss and discoloration, as well as lesions and necrosis spots on the bark of stems and branches. Infected trees have included those in forests, parks, gardens and young trees in nurseries. The fungus killed 90 percent of trees in Denmark.
