Ash Dieback Surveys & Felling

Identify, Plan & Act on Ash Dieback

What is Ash Dieback?

  • Hymenoscyphus fraxineus is an Ascomycete fungus that causes ash dieback, a chronic fungal disease of ash trees in Europe characterised by leaf loss and crown dieback in infected trees.


  • The fungus was first scientifically described in 2006 under the name Chalara fraxinea.

Confirmed Cases in the UK 

  • In 2016 there were many confirmed cases reported in the UK, it has spread across the majority of England & Wales as this map from the Forestry Commission indicates.

  • Ash die back is becoming prevalent in the UK. According to Woodland Trust Ash dieback will kill up to 95% of ash trees across the UK changing our landscape forever.

The significance:

  • Landowners, under both the civil law and criminal law, have responsibility for the health and safety of those on or near their land.​

  • If a tree affected with ash dieback falls, or branches fall, due to the disease, landowners could be liable to pay damages and could even be prosecuted.

  • In the UK, landowners are responsible for undertaking risk management of the dangers, but councils can issue orders to remove trees infected with ash dieback.

  • Under the Highways Act 1980, landowners can also be issued with Section 154 notices to remove infected ash growing on their land and adjacent to the highway that may pose a safety risk.

  • Timber becomes brittle and branches are liable to snap, furthermore the tree itself becomes unstable due to a dying root system and will be prone to wind blow.

  • Landowners must consider public safety and monitor their trees, particularly in areas with high levels of public access.
