The Common Ash tree is becoming less common

A light reduction of an Ash tree!

How beautiful to see a magnificent Ash tree, standing tall in the early morning sunshine! This photo was taken earlier this year by one of our tree surgeons, before the leaves appeared, and after a healthy light reduction by Tree & Lawn Company.
But not all Ashes are faring so well… have you heard of Ash Dieback? It’s a highly destructive disease affecting mostly Ash trees, especially the United Kingdom’s native Common Ash. It was first detected in the UK in 2012 and is now extremely widespread. It’s caused by a fungus known as Chalara and we, at Tree & Lawn Company, are very aware of this disease – we’ve been helping with the control of dangerous trees on some of the UK highways.

According to the Woodland Trust, “Ash Dieback will kill around 80% of Ash trees across the UK. At a cost of billions, the effects will be staggering. It will change the landscape forever and threaten many species which rely on Ash.”

The big problem

Chalara Ash Dieback is a substantial threat in most parts of the United Kingdom. Its effects are most visible in regions where the fungus has been present for the longest time, and where local conditions are most suitable for the fungus. This interactive map, created and maintained by the Forestry Commission, provides greater detail of which parts of the country are most affected. Any new incidences should be reported, keeping the map accurate.

The ongoing solution

Although there is no chemical control available to gardeners for this disease, it’s not all doom and gloom – there are some measures in place to help. There is currently a prohibition on importation and inland movements of ash seeds, plants, or other planting material. Work and more research are also being carried out into breeding tolerant Ash trees for the future.
