    Revised valuation of flood regulation services of existing forest cover to inform natural capital accounts.
    Lead Author: Samantha Broadmeadow
    The ability of trees, woodlands and forests to reduce downstream flooding is increasingly recognised and valued by society, driving a demand for assessments of this important ecosystem service. This study updates a previous evaluation (Broadmeadow et al., 2018) with improved estimates for the volume of flood water potentially removed by woodland or retained by its […]

    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 […]

    Novel dendrochronological modelling demonstrates that decades of reduced stem growth predispose trees to Acute Oak Decline
    Lead Author: Katy Reed
    • Novel dendrochronological modelling was developed to explore oak stem growth trends. • Trees with long-term AOD symptoms may have been predisposed many decades earlier. • Diseased trees struggle to take advantage of favourable growing conditions. • Historic episodes of stress may impact the future resilience of oaks to disturbance.

    Diameter, height and volume increment single tree models for improved Sitka spruce in Great Britain

     The British forestry sector lacks reliable dynamic growth models for stands of improved Sitka spruce, the most important commercial forest type in Great Britain. The aim of this study is to fill this gap by trialling a new modelling framework and to lay the foundations of a future dynamic growth simulator for that forest type. […]

    Simultaneous estimation of Pinus nigra Arn. ssp. salzmannii natural regeneration emergence and survival through lifetime analysis

     We developed a climatic sensitive model to simultaneously estimate the emergence and survival of Corsican pine natural regeneration in Spain through lifetime analysis. This work is highly relevant for managing the species in a context of climate change. Our modelling approach represents a breakthrough in the state of the art of lifetime analysis.

    Forest damage by deer depends on cross‐scale interactions between climate, deer density and landscape structure
    Lead Author: Chloe Bellamy
    This journal paper investigates the factors that drive deer damage to woodlands using the National Forest Inventory sample square data. We found that the likelihood of damage to trees depends on cross-scale interactions between climate, deer density and landscape structure. The complex interactive effects uncovered are difficult to interpret. We therefore provide an interactive Deer Damage Tool for practitioners to visualize how afforestation is likely to influence the probability of deer damage in different forests and regions across Britain.

    A sequential multi-level framework to improve habitat suitability modelling
    Lead Author: Chloe Bellamy
    We provide a sequential framework for improved multi-scale habitat suitability modelling or species distribution modelling. We apply it to the lesser horseshoe bat in Britain to demonstrate its improved accuracy and ecological inference.

    Predicting hedgehog mortality risks on British roads using habitat suitability modelling

     An analysis of citizen science hedgehog roadkill data has revealed why, when and where vehicle-hedgehog collisions are most likely to occur. The approach involved a multi-scale habitat suitability model. Suburban areas with mixtures of urban and grassland were found to be roadkill hotspots.

    Urban Forests in a European Perspective: what can the National Forest Inventory tell us?
    Lead Author: Natalie Marie Gulsrud
    This pilot project demonstrates that the NFI data, in combinationwith the DEGURBA approach, provides existing data onEuropean urban forests. Now that we know what we have, thereis potential to quantify and qualify the state and trends ofEuropean urban forests. Moving forward we can draw onexisting policies and concepts such as ecosystem services tomodel what urban […]

    Assessing the stem straightness of trees
    Lead Author: Andrew Price
    Stem straightness is important in determining tree and log value. The ability to make an effective assessment before harvesting is useful for forest managers and practitioners to improve forecasting, planning, marketing and resource use. This Technical Note describes three methods for assessing stem straightness in standing trees: visual assessment, photogrammetric measurement and terrestrial lidar. It […]

    Timber properties of noble fir, Norway spruce, western red cedar and western hemlock grown in Great Britain
    Lead Author: David Gil-Moreno
    The softwood processing sector in Great Britain has been built around the use of a very small number of timber-producing species – predominantly Sitka spruce. The recent increase in outbreaks of host-specific tree pests and diseases has led to an interest in diversification, through planting a wider range of tree species, to mitigate any risk […]

    Forest Yield: A handbook on forest growth and yield tables for British forestry
    Lead Author: R.W. Matthews
    Yield models are one of the foundations of forest management. They provide information about the patterns of tree growth and potential productivity that can be expected in forest stands of different tree species, with varying growth rates, when managed in different ways. Yield models are in daily use by forest managers and practitioners when making […]
