< Go Back Ash dieback, Hymenoscyphus fraxineus (also known as Chalara fraxinea) Posted: May 28, 2019Ash dieback, Hymenoscyphus fraxineus (also known as Chalara fraxinea), is the most significant tree disease to affect the UK since Dutch elm disease which was first recognised in the 1960s. It will lead to the decline and death of the majority of ash trees in wales and the rest Britain and has the potential to infect more than two billion ash trees1 (over 1.8 billion saplings and seedlings to more than 150 million mature trees) across the country.
This invasive fungus causes ...a range of symptoms from foliar leaf spots to branch dieback to the death of Fraxinus excelsior (ash) trees and some other Fraxinus species. Once infected, most trees will die.
In woodlands, evidence in December 2018 suggests mortality rates may be between 70% and 85%. Evidence from Europe suggests that around 10% of trees were found to be moderately tolerant to the disease, with 1-2% having high levels of tolerance.
It is vital to understand that ash dieback will not be �business as usual� for us At Extreme Tree Services!
Ash dieback is either already in an area or is likely to be in the next few years with potentially serious practical and financial impacts.
Therefore, to manage ash dieback effectively it is best to plan ahead and categories your Ash trees in terms of health with the help one of our team.
If Trees are left The extent of branch death will spread year by year thus increasing the potential hazard from falling brittle branches to persons, property, and vehicles.Delaying action results in the trees being too dangerous to climb and therefore problematic to make safe.
