    Green spruce aphid (Elatobium abietinum) research

    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.

    DIAROD research summary

    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.

    Climate change impacts on insect pests associated with Sitka spruce

    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.

    Living Ash Project phase I (LAP)

    The specific objectives of Forest Research in the Living Ash Project are to establish new genetic trials to whether, and to what extent, tolerance of ash trees to damage caused by ash dieback is governed by genetics. The genetic trials will enable us to understand how much responses vary among families, whether breeding trees will incur a cost for tree growth and form and explore whether and how this changes over time.

    Phytophthora austrocedri – Pest Alert

    Lead Author: Forestry Commission
    Phytophthora austrocedri (previously spelled austrocedrae) is an aggressive, fungus-like pathogen that poses a serious threat to juniper trees in Britain. Juniper is an important native species and a significant proportion of the small area of juniper woodland in Britain is protected. Phytophthora austrocedri was first reported in the UK in 2011, and infected trees have […]

    Horse chestnut bleeding canker

    Lead Author: Sarah Green
    Horse chestnut is an important amenity tree species which has been significantly affected over the past decade by a widespread outbreak of bleeding canker disease. Symptoms include rust-coloured or blackened bleeding cankers on the stem and branches, which can lead to tree mortality. The causal agent of this disease is the pathogenic bacterium Pseudomonas syringae […]

    Elm yellows – Pest Alert

    Lead Author: Forestry Commission
    Elm yellows is a disease of elm trees caused by a type of bacterium known as a phytoplasma. Symptoms of the disease can range from yellowing of leaves to dieback of foliage and branches. Elm yellows has been found affecting elm trees in North America and a few European countries, but in 2014 it was […]
