Have you ever thought about what the world would be like without trees?

Trees are a fundamental element of our natural environment.


They give us social and economic benefits, increasing our quality of life.

Many bird species and small animals find trees a perfect habitat for shade, food and nesting.

Trees add beauty to their surroundings and contribute to the character of their environment and neighbourhoods.

Your help is crucial

Join the fight against tree disease.  By working together, raising concerns sooner, we have the best chances of preserving our landscapes.

Three key pests and diseases are threatening some of the UK’s most iconic tree species and we want you to look out for them:

Chalara ash dieback
Affects ash trees
First recorded in the UK in 2012
Sirococcus blight of cedar
Affects cedar trees
First recorded in the UK in 2013
Oriental chestnut gall wasp
Affects sweet chestnut trees
First recorded in the UK in 2015

To help you we have created a toolkit for each one.  You can access these by clicking on the pictures immediately shown above.

These toolkits give you the resources to help you recognise signs and symptoms as well as document key information. A wide range of further information exists on these, and many more, tree pests and diseases. Signposts and links are provided.
