The battle against tree-disease spreading beetles such as the Emerald ash borer and the larger eight-toothed spruce bark beetle has taken a significant step forward today thanks to new government funding.

The funding will pay for a new £4 million research and containment facility at the UK’s Forest Research Alice Holt Research Station in Surrey and will better equip the country in managing the risks posed by these harmful pests and pathogens, in plans unveiled today (Friday 10 May) by Defra and the Forestry Commission as part of National Plant Health Week.

The new facility will expand the capacity of the existing Holt containment laboratory by almost double. This will boost capability to study pests and pathogens in a contained and controlled environment – enhancing our national response and facilitating safe international trade.

Statistics released by Forest Research today show there were 2350 tree pests and diseases reported via the TreeAlert service service from April 2023-March 2024.

By assessing the pests and pathogens in a contained laboratory, scientists from Forest Research – Great Britain’s leading organisation for forestry research – will be able to study them in a safe and controlled manner using cutting-edge technology and equipment to safeguard our treescapes.

Biosecurity Minister Lord Douglas-Miller said:

The UK is a world leader in tree health and biosecurity and today we are going further in boosting our armoury to combat tree pests and diseases and manage emerging threats.

We are committed to protecting the country’s tree health and maintaining biosecurity to ensure our trees and woodlands are resilient to fight climate change. Building on the existing vital work of Alice Holt will be a key part to achieving this.
