How can a fungus be such a danger to ash?

The British government has reacted to the spread of Ash dieback by banning Ash imports to the UK. The Food and Environment Research Agency have released a video explaining how the life cycle of the fungus Chalara fraxinea can spread through Ash.

The Forestry Commission also has guides on how to recognise the symptoms of a Chalara fraxinea infection. If you’re from outside the UK, news sites covering this story include the BBC, the Guardian and Channel4.
