We have recently been carrying out the removal of Ash trees that are suffering from Ash Dieback disease that are growing on the motorway embankments on the A1M between Dishforth and Darrington, that we maintain on behalf of Tarmac. These can pose a potential risk to road users if left to decay.
Ash Dieback is a serious tree disease affecting ash trees across the UK and much of Europe. It is caused by a fungus called Hymenoscyphus fraxineus.
The disease attacks the tree’s leaves, branches, and bark, eventually weakening or killing the tree. In the UK it mainly affects the European ash (Fraxinus excelsior).
Ash dieback was first confirmed in the UK in 2012 and is expected to kill millions of ash trees over the coming decades. This affects woodland ecosystems, wildlife, and hedgerows.
Small Bit of Good News 🌱
Research has shown that about 1–5% of ash trees may have natural resistance, so some trees will survive and help restore ash populations in the future.
