Investigate how to incorporate biodiversity into an optimal rotation length model through literature review and data re-analysis of biodiversity links with stand age.

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.

UK distribution of Phytophthora ramorum evolutionary types provided by new testing method. By developing a new molecular-based testing method based on PCR techniques, Forest Research scientists have been able to examine the distribution of the two main lineages of Phytophthora ramorum responsible for the major epidemic on larch (Larix spp.)...

News of a recent unwelcome discovery and how ‘citizen science’ can play an important role in surveying and identification. An overview of the 2015 discoveries of Dryocosmus kuriphilus (Oriental chestnut gall wasp; OCGW) in European sweet chestnut (Castanea sativa) trees in Farningham Woods, Kent and St Albans, Hertfordshire, was published...

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...

This project is exploring the threat to UK forestry posed by the Pine-tree lappet moth (Dendrolimus pini) and whether it is an introduced pest species or a previously undiscovered resident.

The DIAROD programme aims to provide the required evidence base for Dothistroma needle blight (DNB) to enable its invasiveness and associated risks to be determined, and hence help prevent its spread, and better enable countries to manage this and future outbreaks of other pests and diseases.

The project is analysing data on spruce aphid populations from forests managed using different silvicultural systems, to determine whether increasing the structural diversity of forest stands leads to a lower incidence of the pest and a reduction in damage.

This project will improve our understanding of how oak processionary moth populations behave in different habitats, which is essential for effective management, and it will provide information on parasitoids and predators that may be useful in biological control of the pest.

This project is carrying out experimental trials to improve and standardise the use of pheromone traps for monitoring populations of oak processionary moth.

This project is investigating the potential impact that a changing climate may have on the insect pests associated with the UK’s most important and widely planted conifer tree species Sitka spruce.

This project involves long-term monitoring of horse-chestnut trees to determine the impact of horse-chestnut leaf miner and bleeding canker disease on tree growth and survival.
