Find out more about the threats facing our forests and woodlands in the tree pest and disease information sheet series for children and young people. 

Our forests are at risk from tree pests and diseases. These can dramatically affect the health of our trees, upsetting the delicate ecosystem balance and devastating large areas of woodland.

Pests and diseases hitch a ride in mud and debris on shoes, paws and tyres, ending up in new forests. Here, they can spread rapidly in environments with no natural resilience.

We're doing everything we can to tackle these challenges, but we need your help too.

What you can do to help protect our trees

You're the best defence our trees have. Before a forest visit, remember to clean your shoes, bike, any toys or equipment and your dog too.

Just take a moment to brush off any visible dirt, and give everything a good wash. This helps slow disease spread, preserving our woodlands now and for future generations.

If you are a land owner or manager you can download a standard poster and an editable version to advise visitors about biosecurity.

Together we can keep our forests healthy

Together we can keep it clean
