What is Ash dieback?

The importance of looking after our countryside

Ash trees are the third most common native tree in the UK, found in woodlands and other landscape settings. As England's most wooded county, Surrey has a lot of ash trees, which are sadly affected by this disease. Over the coming months you will see some work being done across our countryside to manage this.

What is Ash dieback?

Ash dieback is caused by a non-native fungus called Hymenoscyphus fraxineus that weakens a tree's structure. Affected trees often see their leaves and branches dying higher up the tree, with the tree becoming weak and unpredictable. It is untreatable and it's important it's managed correctly.

Managing Ash dieback in our county

Our countryside team are working with partners to manage the risks posed from dying ash trees. In the new year, there are plans to remove diseased trees for public safety at a small number of sites subject to the granting of relevant licenses and permissions.

You will be able to find further details as they are released ahead of any works commencing on the Ash Dieback web page and onsite information at affected sites.

You can also find out more about what we're doing over the coming months to achieve our goal of planting 1.2 millions trees in Surrey by 2030, in one of our Surrey Matters web pages.
