    Pine processionary moth – Pest Alert

    Lead Author: Forestry Commission
    Pine processionary moth is a serious pest of pine trees in southern Europe. The moth larvae (caterpillars) feed on pine needles and defoliate trees, which reduces tree growth and timber production. Large numbers of larvae can cause severe damage – weakening the trees sufficiently to make them vulnerable to other pests and diseases and, in […]

    Chestnut blight – Pest Alert

    Lead Author: Forestry Commission
    Chestnut blight is a serious disease of chestnut trees caused by the fungus Cryphonectria parasitica. The fungus does little damage to host trees in its native range in Asia, but has devastated American chestnut when it was accidentally introduced to the USA more than 100 years ago via infected planting stock. The disease was introduced […]

    The influence of climate change on forest insect pests in Britain

    Lead Author: David Wainhouse
    Predicting future risks of damage by insect pests is an important aspect of forest management. Climate change has the potential to affect forest pests and their impact on trees through higher temperatures, altered precipitation patterns, and more frequent extreme weather events. Warmer temperatures are likely to have complex effects on insects, influencing, among other things, […]

    Understanding the threat posed by Phytophthora austrocedri to juniper in Britain

    Phytophthora austrocedri is causing widespread mortality of native juniper in northern Britain. This project aims to provide the evidence base to guide juniper conservation strategies that mitigate the effects of the pathogen.

    Do non-native conifer plantations provide benefits for a native forest specialist, the wood ant Formica lugubris?

    Lead Author: Duncan Procter
    Recent research by Forest Research scientists and colleagues at the University of York shows that northern hairy wood ants (Formica lugubris) have successfully colonised plantations of largely non-native coniferous species in the North York Moors National Park. The studies show that there has been a remarkable expansion of the population of this ant into new […]

    Xylella fastidiosa – Pest Alert

    Lead Author: Forestry Commission
    Xylella fastidiosa is a disease-causing bacterium that affects a wide range of important woody plants and broadleaved trees. It invades the xylem vessels that transport water throughout plants, and causes symptoms ranging from leaf scorch to tree dieback and death. In the natural environment it is transmitted by xylem-fluid feeding insects such as leafhoppers. Until […]

    Plane wilt (canker stain disease) Pest Alert

    Lead Author: Forestry Commission
    Plane wilt, also known as canker stain disease, is a serious disorder of plane trees, which are important amenity trees in the parks and avenues of many European cities. The disease is caused by the fungus Ceratocystis platani, which is present in the USA and Europe, but considered to be indigenous only to North America. […]

    Future Proofing Plant Health

    The Future Proofing Plant Health project aims to provide evidence for the implementation of the GB Plant Biosecurity Strategy. It will focus on strategic areas related to new and emerging pests and diseases (prevention, detection, control, resilience), as well as identifying priority pests, diseases and pathways.

    Hot-water treatment as a possible method for eradicating Chalara fraxinea (Hymenoscyphus pseudoalbidus ) infection from ash fruits (Fraxinus excelsior L )

    Lead Author: Shelagh McCartan
    Treating ash seeds with hot water may kill Chalara infection Immersing ash seeds in 44°C water for 5 hours may eradicate Chalara infection in ash seeds without significantly reducing the viability of the seeds. Forest Research scientists have published the results of this trial in Quarterly Journal of Forestry. Batches of ash fruits were subjected […]
