Ash Dieback, a serious disease affecting ash trees across Europe and the UK, has brought a green menace to our cherished woodlands and landscapes. As it continues to spread, the impact is not only visible in our countryside but also in the risks it poses to biodiversity, property, and public safety. 

What is Ash Dieback? 

Ash Dieback, caused by the fungus Hymenoscyphus fraxineus, was first described in Poland in 1992 and has since spread to many other countries. It affects Fraxinus species, particularly the European ash (Fraxinus excelsior), leading to leaf loss, crown dieback, and eventually, the death of the tree. 

Causes:  The Spread of a Disease 

The disease spreads through spores carried by the wind, which can travel up to 20 miles. These spores can infect trees through leaves, particularly in the damp, cool conditions the fungus thrives in. Once established, the fungus obstructs the water transport systems within the tree, causing it to weaken and eventually die. 

The Impact: Beyond the Trees 


Ash trees are a key component of our woodlands and provide a habitat for a wide range of species. 

Safety Hazards 

Infected trees, particularly those near paths, roads, or buildings, pose a risk as their weakened structure makes them more likely to fall. 

Economic Loss 

Ash is a valuable hardwood used in various industries, from furniture making to sports equipment. 

Solutions & Management 

Early Detection 

Identifying symptoms early can help in managing the spread. 

Removal and Disposal 

Infected trees, especially those posing a danger to the public, need to be removed safely and disposed of appropriately to prevent further spread. 

Biosecurity Measures 

Cleaning tools, vehicles, and clothing that have been in contact with infected trees can reduce the risk of spreading the disease. 


Encouraging the growth of a diverse range of species to replace lost ash trees can help in maintaining the ecological balance. 


Professional tree surgery companies are on the frontline in the battle against Ash Dieback. With their expertise, they play a crucial role in managing the disease 

Expert Assessment 

Arborists can identify the disease and assess the extent of the infection. 

Safe Tree Removal 

They have the skills and equipment to safely fell and remove infected trees, especially those that pose a risk to structures or people. 

Advice & Guidance 

Tree surgeons can provide advice on the management of ash trees to prevent the spread of the disease and on suitable species for replanting. 

Continued Care 

They can also help with the ongoing care and monitoring of trees to ensure their health and safety. 
Ash Dieback is a serious threat that requires attention and action from all of us. Professional tree surgery companies offer valuable expertise and practical solutions to manage the disease and mitigate its impact. By working together, we can help protect our trees and the myriad of benefits they provide for generations to come. 
As responsible stewards of the environment, seeking professional advice and services is not only a practical choice but also an ethical commitment to preserving our natural heritage.
