Tree Pests and Diseases


The threat to trees from pests and diseases is growing due to increases in global travel, economic globalisation, and the effects of climate change.

The risk to our trees and forests is real and significant. Pests and diseases can spread rapidly in new habitats where there are few natural checks and balances.

Beyond visible damage to leaves, shoots and bark, the impact on timber quality can have a serious negative effect on both the volume and value of forest products. 

Healthy, thriving trees and forests are important for many other values and benefits of woodland. These include habitat for wildlife, recreational facilities for people, diverse and beautiful landscapes.
