Ash tree dieback

 The fungal infection Chalara fraxinea, which has ravaged other European countries and now spread to the UK, causes leaf loss and crown dieback in affected trees. It kills 90 per cent of the trees it affects. In the UK there are an estimated 80 million ash trees, taking up around 30 per cent of woodland across the country.

Imports of ash trees into the UK have been banned since 30 October 2012.
