Experts at the University of East Anglia (UEA) based in Norwich have developed a smartphone app designed to help fight the deadly ash dieback disease.
Environmental specialists said the app would not only help monitor the spread of disease, but allow conservationists to target infected areas.
So far 100,000 trees have been destroyed in an attempt to stop the spread.
The disease was first spotted in the UK in February at a nursery in Buckinghamshire. It has now been found in the wider countryside in East Anglia.
