A Woodland Trust worker disinfects his boots at Pound Farm Woodland, where many ash trees have been identified as having Ash Dieback Disease, near Ipswich, England. The outbreak has the potential to devastate the U.K.'s population of 80 million ash trees. The first confirmed case in the country was in March, and since then, the disease has been confirmed at another 82 sites, with woodlands in Norfolk, Suffolk, Kent and Essex among the worst affected; it has now spread to Scotland. Dieback is caused by the fungus Chalara fraxinea. It was first recorded in Eastern Europe in 1992 and has since spread to infect most of the continent.
