Submitting a sighting will help inform experts in the Living Ash Project understand more about the spread of the disease. Your tree could be important in helping ash trees across Britain recover from ash dieback.

Need help tagging a tree for the first time? Watch our video for a step-by-step guide.

Have multiple photos? Just submit a sighting for each.
Need help identifying ash trees? See our identification guide.
Drag the pin (or click elsewhere) to move the location. The more accurately you position the pin, the easier it will be for others to find the tree again later.

In your opinion, how likely is this tree to have Ash Dieback Disease?

Now complete the main survey to help scientists breed healthy ash trees for the future. Simply answer a few more questions about your tree.

Living Ash Project survey

Scientists who in the Living Ash Project are interested in ash trees that are tolerant (to some degree) to Chalara ash dieback. They are particularly keen to survey ash trees in every corner of Britain, because the genetics of ash trees vary across the country. Ideally, the trees selected need to be surveyed every year for at least three years, so that a detailed picture of their health is built up. Ultimately, trees that appear to have some tolerance to Chalara ash dieback will be sampled by taking cuttings, and will enter a programme aiming to breed resistant trees for the future of ash trees in Britain.

All questions are optional

Can you see any disease symptoms?

Tick any that apply

Estimate the diameter of the tree’s trunk at chest height.

Large trees appear to be more tolerant to Chalara ash dieback.

Estimate the diameter of the tree’s trunk

Describe the environment where your tree located

The environment where the tree is growing can affect the chances of it being exposed to the disease, and affects its general growth characteristics, which are also of interest to scientists.

Are other nearby ash trees visible from your tree?

The presence of ash trees nearby increases the likelihood that your tree may be exposed to the disease.

If another ash tree is nearby, please visit it and tell us:

Scientists are interested in this question because if your main tree appears healthy, yet nearby there are diseased trees, this increases the likelihood that your main tree is tolerant to the disease.

How likely is this tree to have Chalara ash dieback?

If you want, you could also tag this tree and add it to AshTag.

Thank you for taking part. It will important for the project that you resurvey the tree in future. You will be contacted again to prompt you.

Remember to keep your eyes open for tolerant trees. If you find any, you can survey them and add them to AshTag.
