The UK’s iconic oak trees face a fight for survival against multiple pests and diseases that have the potential to devastate the oak population.
These threats include:
Oak processionary moth
Acute oak decline
Xylella fasitidiosa
Root-attacking species of honey fungus
Powdery mildews
Losing oak trees from our landscape will impact our well-being, economy, environment and the species that depend on them.
Research and monitoring has begun but we must do more to ensure we protect our majestic oak trees for future generations to enjoy.
