At risk of Chalara dieback, Fraxinus Excelsior Altena trees or Common Ash for sale at J Jones Nursery in Southport, Merseyside, UK
Ash dieback, also known as Chalara dieback of ash, is a serious disease that is killing ash across Europe. Ash is a very important tree in the UK both ecologically and culturally so this disease is causing great concern about the damage it will do. What is ash dieback? Ash dieback affects ash trees (Fraxinus excelsior) and is caused by the fungus Hymenoscyphus fraxineus (previously known by the names Chalara fraxinea and Hymenoschyphus pseudoalbidus). It blocks the water transport systems in trees causing leaf loss, lesions in the wood and on the bark and ultimately the dieback of the crown of the tree. This disease was first described in Poland in 1992 and has since swept westwards throughout Europe. It was first identified in Britain in 2012 in nursery stock then in the wider environment in 2013 although it could have been in the country much longer. The number of confirmed findings is continuing to increase and the distribution is reported by the Forestry Commission on a regular basis.
