Ash trees are fighting back against a disease that has ravaged the British countryside, new scientific evidence shows.

When ash dieback arrived in 2012, predictions suggested up to 85% of ash trees could be lost.

But now scientists have discovered that ash woodlands are naturally evolving greater resistance to the infection.

The discovery offers renewed hope that the much-loved trees will survive in the British landscape.

"It is hope born out of the death of a lot of trees," said Prof Richard Buggs of the Royal Botanic Gardens Kew, and Queen Mary University of London.
