Tree Health England

Monitoring tree health and protecting our trees, woods and forests from pests and diseases is an increasingly important part of sustainable forest management. This is because a number of exotic tree pests and diseases have entered the UK in recent decades, mostly in association with the expansion of global trade but there is significant risk of others entering too via other means.

Forestry Commission England’s Tree Health Team handles the surveillance, monitoring, identification and management of sites across England where a disease is suspected or confirmed to be present in woodland or forests.

We are constantly monitoring, and working, to minimise the spread and impact of a number of pests and diseases of trees and other woodland plants. We also work with our partners in government and industry to try to keep out exotic plant pests and diseases which could be damaging if they entered the UK.

This work is supported by communications to raise awareness of pests and diseases, which includes guidance on ‘biosecurity’ measures which we should all take so that we do not help them spread.

If you have any concerns the information provided below should help you find the information you need, when you need it.
