Tree health

Part of our mission is to protect trees, woodlands and forests from damaging influences and we work with partners across Great Britain to control the threat from plant pests and diseases.

With the recent increase in findings of new pests and diseases, Britain's trees are facing unprecedented threats - see the links below for information on pests and pathogens and the work of our Plant Health Service.
