This fungus has two phases to its life-cycle: sexual and asexual. The asexual stage, which grows in affected trees, attacking the bark and girdling twigs and branches, was the first to be described by science, and called Chalara fraxinea. This gave rise to the common name of the disease which it causes.
Should you cut down trees with ash dieback?
DO NOT cut ash trees or ash-dominated hedgerows during the bird-nesting season if this can be avoided. Spore production from diseased ash leaves is highest during the summer, so disturbance of trees during this time might also increase dispersal as well as disturbing protected wildlife.

Should all ash trees be cut down?
Dying ash trees or already dead ones can be hazardous and must be cut down. Sometimes, it might have been infested with the emerald ash borer, and the owner must cut it down. All these situations, necessitate ash tree removal.
Can you burn diseased ash wood?
Would you recommend burning ash borer wood? Go for it! You can safely burn wood from trees infested by EAB. Just be sure to use it at the location where the trees were removed.
What is Ash Dieback?
Caused by a non-native fungus from overseas, Ash Dieback is now being found mainly in the south-east of the UK but has been reported across the country. It is presenting a threat to our landscape on a scale not seen since the heart-breaking Dutch elm disease epidemic in the 1970s.
Where did it come from?
This horrid disease originated from Asia, where it doesn’t cause much damage to the native species. However, our European Ash Trees have not naturally evolved with the fungus in their habitats and therefore have no resilience to it.
What is being done about it?
We can’t eradicate this terrible disease, so we must place our attention on conserving the healthy ash trees while helping our wildlife to adapt to an environment without them.
What can you do at home to help?
By building awareness of this devastating disease, we can encourage others to take care and help stop the spread. It’s suggested that by cleaning your shoes before and after visiting woodland and avoid taking cuttings or plant materials from the countryside, you can help.

The spores of this fungus can travel in the wind so it is possible that it arrived in the UK naturally however it was also inadvertently imported on ash saplings. The UK was importing thousands of ash plants from infected parts of Europe until a ban came into place in 2012.

As well as aiming to retain as many potentially tolerant ash trees as possible, letting nature take its course by allowing diseased ash trees to decline, we also improve the resilience of our woods to future diseases and climate change. We do this by increasing the genetic diversity of trees in existing woods. And when planting new woods, we use a mix of native tree species.
Where did Ash Dieback originate?
