Living Ash Project

Securing the future for ash trees in Britain

Ash dieback map March 2017

The arrival of Chalara ash dieback in the UK is a serious threat to our native ash trees and the nature of our woodlands. With over 120 million ash trees in Britain, it will also dramatically alter the appearance of our landscape. Many wildlife species only live on ash trees, so if we lose the ash, these species too may also vanish.

In October 2015 we recorded the disease in our national research woodland Paradise Wood.

The map shows how far the disease has spread in the last five years - further details can be found on the Forestry Research website.

Earth Trust is leading the Living Ash Project, funded by Defra, aiming to identify ash trees with tolerance to the disease. 

What we’re doing

Evidence from Denmark, where Chalara is more prevalent, indicates that approximately 1% of trees show good resistance. Natural selection will produce disease-resistance trees; quickly identifying these and using them in a breeding programme will enable us to rapidly produce resilient trees. 

March 2017 key

Disease-resistant trees will provide a genetically diverse and resilient population for future productive woodland planting.

Earth Trust is the home of Paradise Wood, an national research woodland, and the largest genetic collection of timber trees and a breeding programme for ash trees. Working with project partners, we have been working on breeding ash for over twenty years and have assembled a substantial collection of ash trees from across the species native range, which has great genetic diversity.

What you can do

You can help us save our amazing ash trees... 

Be vigilant 

Please be aware that if you see ash dieback on your walks you may accidentally spread the disease.  Please clean your foot wear after visiting areas with infected trees to reduce the chance of spreading the disease.

Please use #LivingAshProject when talking about ash dieback on social media.
