Trees face killer disease threat

Thousands of conker trees on streets in Nottinghamshire may have to be cut down if they are found to be infected by a deadly disease.

Experts are monitoring the horse chestnuts for bleeding canker, a disease which has already appeared in trees in parts of the county.

The fungus eats around the bark and can kill the trees, leaving them in a dangerous condition.

Signs of infection include brown leaves and fewer conkers.

It costs about £1,000 to remove and replace each tree.
