Tree news: Ash dieback disease

What is it?

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.

When was it found?

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.
