    Acetamiprid used to prevent Hylobius abietis damaging young trees poses a very low risk of causing water contamination provided good forestry practices are followed

    Lead Author: Huw Thomas
    A study of chemical runoff following the use of acetamiprid as a pre-treatment and top-up spray to prevent damage from the large pine weevil (Hylobius abietis L.) to young trees was undertaken at a restock site in mid-Wales. The site was specifically selected to pose a high risk of chemical runoff, being a high elevation, […]

    Designing and managing forests and woodlands to reduce flood risk

    Flooding is a major environmental hazard facing the UK and one that is expected to increase with climate change. Societal impacts and economic damages are likely to escalate, with major floods already costing multiple £billion. These concerns are driving a more sustainable approach to flood risk management involving greater working with natural processes to slow […]

    An analysis of conifer experiments in Britain to identify productive alternatives to Sitka spruce

    Lead Author: Victoria Stokes
    An analysis of relevant species trials was carried out to assess the productivity of potential alternative conifer species to Sitka spruce on upland site types in Britain. Data from 87 forest experiments planted between 1929 and 1995 were analysed to compare long-term performance of 52 species with that of Sitka spruce under the same conditions and site type.

    Intimate mixtures of Scots pine and Sitka spruce do not increase resilience to spring drought

    Lead Author: Tom Ovenden
    Understanding how we can increase the resilience of forest systems to future extreme drought events is increasingly important as these events become more frequent and intense. Diversifying production forests using intimate mixtures of trees with complementary functional traits is considered as one promising silvicultural approach that may increase drought resilience. However, the direction and magnitude […]

    How resilient are planted UK forests to drought? A summary of recent research on Sitka spruce and Scots pine.

    Lead Author: Tom Ovenden
    As our climate warms, the pressures on global forest ecosystems from extreme climate events are expected to increase across much of the world (Anderegg et al., 2020; Brodribb et al., 2020). Of particular concern is the increasing threat to tree health and productivity posed by drought. Despite a predominantly cool maritime climate, forest ecosystems in […]

    The potential of the selective graminicides cycloxydim and propyzamide as habitat improvement tools for the pearl-bordered fritillary butterfly

    Lead Author: Matt Parratt
    The pearl-bordered fritillary (Boloria euphrosyne) is a resident UK butterfly which is in decline, partly because grasses can outcompete its preferred food plant, common dog-violet (Viola riviniana). We therefore investigated whether using graminicides could help to enhance the habitat quality of a violet-rich butterfly ride. Applications of 1.5 kg a.i. ha-1 propyzamide or 0.45 kg a.i. ha-1 cycloxydim both reduced grass cover and were associated with an increase in violet plants. Our work suggests that enhancing pearl-bordered fritillary habitat may not always be possible through herbicide use alone, but cycloxydim may have a useful role in helping to reduce competition from grasses.

    Scenario analysis: exploring future woodland use and ecosystem services delivery

    Lead Author: Darren Moseley
    Land use change has been one of the major influences on UK forests and wooded landscapes for many years, with the future likely to be affected through changes in climate and human population pressure. This presents a challenge for the long-term planning and management of woodlands to provide the range of goods and benefits (i.e. […]

    Adapting forest and woodland management to the changing climate

    Lead Author: Gail Atkinson
    Our climate is changing rapidly, with milder, wetter winters, warmer summers, longer growing seasons and more frequent extreme conditions, including drought periods and heavy rainfall events. The projected rate of climate change is unprecedented and therefore action is essential now to improve the resilience of forests and woodlands, and to protect the benefits that they […]

    Factsheet: Climate change and urban forests

    Lead Author: Kieron Doick
    Urban forests can both help reduce climate change and help urban society cope with its impacts.

    Factsheet: Climate change adaptation

    The changing climate is affecting our trees, forests and woodlands, how they grow and survive and the important ecosystem services they provide. For our forests and woodlands to thrive, adaptation measures must be considered carefully, and action taken. Ten measures to reduce climate risks and improve resilience are presented.

    Factsheet: Climate change and tree diseases (canker)

    Lead Author: Carolyn Riddell
    Canker-inducing pathogens kill the inner, living bark of trees resulting in poorer growth or mortality of affected individuals which limits their contribution to climate change mitigation.

    Factsheet: Climate change and tree diseases (Phytophthora)

    Lead Author: Debra Fredrickson Matika
    Milder and wetter winters, followed by increased spring rainfall, are likely to enhance the survival and infection potential of many tree pathogens. Hotter, drier summers leading to drought stress in trees will also increase their susceptibility to disease and expand the distribution range of some pathogens. The increased incidence and severity of diseases caused by Phytophthora species reduces the benefits that trees provide, including climate change mitigation.

    Threshold Response to Extreme Drought Shifts Inter-Tree Growth Dominance in Pinus sylvestris

    Lead Author: Tom Ovenden
    Many studies quantify short-term drought impact on tree growth relative to pre-drought growth averages. However, fewer studies examine the extent to which droughts of differing severity differentially impact tree growth or shape stand dynamics. Focusing on three droughts in high and low density stands of Pinus sylvestris in Scotland, we calculated pre-drought growth averages using […]

    Life after recovery: Increased resolution of forest resilience assessment sheds new light on post-drought compensatory growth and recovery dynamics

    Lead Author: Tom Ovenden
    Understanding the impacts of extreme drought on forest productivity requires a comprehensive assessment of tree and forest resilience. However, current approaches to quantifying resilience limit our understanding of forest response dynamics, recovery trajectories and drought legacies by constraining the temporal scale and resolution of assessment. We compared individual tree growth histories with growth forecasted using […]

    Comparison of the carbon, water, and energy balances of mature stand and clear-fell stages in a British Sitka spruce forest and the impact of the 2018 drought

    Lead Author: Georgios Xenakis
    Sitka spruce is the major conifer species in British upland forests and is predominantly managed as even-aged, single-species plantations with rotation lengths of less than 50 years using a “patch clear-felling” system. Evidence on the impact of clear-felling on the carbon, water and energy balances of plantation forestry is sparse and extreme weather events, such […]
