Here in Britain, ash trees (Fraxinus excelsior) are under attack by a fungus (Chalara fraxinea) which causes the disease called ash dieback. This is one of several emerging diseases now threatening our trees.
The ash dieback story has gone quiet in the news, probably because it’s winter here now and all the deciduous trees are leafless. Including ash trees. But ash dieback hasn’t gone away. When spring comes, there’ll be ash trees whose leaves don’t grow back, or which grow back then droop with ash dieback.
Here’s what the Centre for Agricultural Bioscience International (CABI) says about the ash dieback story so far. You might choose to look at Fraxback. I’m glad to see that the disease is being monitored, and that research is continuing. But this story isn’t finished. The Fat Lady’s not singing yet.
