Chalara dieback of ash is a serious disease of ash trees caused by a fungus called Chalara fraxinea. The disease causes leaf loss and crown dieback in affected trees, and it can lead to tree death.
Following an outbreak in this country, Chalara fraxinea is being treated as a quarantine pest under national emergency measures, and it is important that suspected cases of the disease are reported.
How to spot Chalara ash dieback symptoms
If you have leaf litter from Ash trees and are unable to dispose of this in your own garden on a bonfire or by home composting, you can continue to place this in your brown bin for collection. All green waste collected from brown bins is sent for composting.
