Tree news: Ash dieback disease

Chalara dieback of ash is a serious disease of ash trees caused by a fungus called Hymenoscyphus fraxineus. The disease causes leaf loss and crown dieback in affected trees, and usually leads to tree death.

In February 2012 it was found in a consignment of infected trees sent from a nursery in the Netherlands to a nursery in Buckinghamshire, England. Since then it has been found in a number and variety of locations in Great Britain, including urban landscaping schemes, newly planted woodland, and more nurseries.

Hastings Borough Council will be especially vigilant during this Chalara breakout.

Hymenoscyphus fraxineus is now being treated as a quarantine pest under national emergency measures and any suspected sighting should be reported.

If you think you have seen Hymenoscyphus fraxineus or you would like more information, contact the Forestry Commission or telephone 0845 051 8486.
