With dire warnings about a fungal disease which threatens to devastate Britain's 80 million ash trees, Simon Bateman from the Woodland Trust explains how to check whether your local trees have been affected.

The fungal infection chalara fraxinea, which has ravaged other European countries and now spread to the UK, kills 90 per cent of the trees it infects.
According to the Forestry Commission, there are several key signs of the disease:
* Leaves begin to die at the crown of the tree.
* Dark lesions, often long, thin and diamond-shaped, appear on the trunk, centred around the base of dead shoots.
* The tips of shoots become black and shrivelled.
* The veins of leaves, normally pale in colour, turn brown.
