A guide to exploring 380 of the most scenic, wildlife-rich and historically significant woodlands in England. From precious remnants of temperate rainforests to lesser-known wildwoods and urban copses, English woodlands offer places of sanctuary for both wildlife and people. In this practical guide, woodland expert Gabriel Hemery brings together the beauty, purpose, history and wildlife of some of the most extraordinary woodland sites in England, from the largest (covering thousands of hectares) to the smallest copse of just a handful of trees and everything in-between. Some woods are havens for rare wildlife such as hazel dormouse and pine marten. Others offer opportunities to explore archaeological features and discover England’s hidden histories. The book is divided into eight regions, each beginning with a summary of its woodland heritage. The 380 site entries contain details of ownership, designation, area, forest type, precise access details (including grid reference, post code and what3words reference) and a description of key features of interest. With clear regional maps and hundreds of remarkable photographs showcasing England's plants, animals and landscapes, this is an essential book for adventurers, ramblers and wildlife enthusiasts. Wherever you may be in England, with this guide you will never be far from a fascinating forest site.

Abstract Forests occupy a pivotal position in addressing the intertwined crises of climate change, biodiversity loss, and sustainable resource use. Yet, the United Kingdom, one of Europe’s least-wooded and most nature-depleted nations, faces persistent barriers to resilient forest management: low forest cover, narrow species diversity, dependence on timber imports, and fragmented ownership. Building on a national horizon scan conducted in 2022, which identified ‘catastrophic forest ecosystem collapse’ as the most pressing emerging issue, this paper explores how artificial intelligence (AI) can strengthen foresight and policy coherence. Although large language models and other AI tools were technically available during the 2022 horizon-scanning exercise, their use in environmental foresight was not yet methodologically normalized or institutionally validated. The absence of AI from that process should therefore be understood less as an omission than as evidence of a rapidly changing methodological context. We propose an AI-assisted horizon-scanning framework that combines AI-enabled signal detection and synthesis with expert interpretation, deliberation and judgement through six iterative stages: framing, signal discovery, expert engagement, synthesis, simulation, and reflexive learning. The framework operationalizes principles of Responsible Research and Innovation and Responsible AI to ensure transparency, accountability, and ethical governance while addressing the ‘data deserts’, institutional fragmentation, and limited place-sensitive decision-making that currently limit the deployment of AI in the forestry sector. A concept for a UK Forestry Foresight Lab is advanced as a practical institutional mechanism linking government, research, and landowners through federated data commons. The paper outlines how ethically-governed AI can transform horizon scanning from a static expert exercise into a dynamic, adaptive and place-sensitive foresight system, supporting sustainable forest governance across the UK’s devolved administrations.

The managers of private forests have critical roles in responding to forest health challenges. Basic knowledge of how they interpret and understand the health of their trees is, however, very sparse. Via an online survey of private forest managers in Britain, we reveal the basic characteristics of this group's understandings of tree and forest health both in general and, more specifically, in relation to the health (and ill health) of oak species. The survey generated 441 valid responses – from forest owners, forestry agents and other professionals. The majority of our respondents believe the forest(s) they manage to be healthy or very healthy, although vulnerable to future threats. We identify key themes within managers' understandings of the factors that promote tree health, and describe the visual signs of good- and ill-health used by them as indicators. Oak trees and oak woodlands were similarly judged to be healthy currently, but again this positivity was set against a sense of vulnerability and potential future decline. The biggest threat to oaks was considered to be browsing and bark stripping by mammals – a very long standing concern – rather than more recently emergent threats. Through this research we provide a clear sense of how forest managers think about, and make judgements on, the health of their trees and forests. This understanding needs to inform the increasing efforts by the forestry sector in engaging private forest managers in forest protection.

Woodland creation has become an important objective for a variety of stakeholders to help tackle the climate and biodiversity crises. One of the key evidence needs is a better understanding of the multiple factors influencing the willingness and ability of landowners and managers to establish new woodlands. To address this gap, a systematic map of evidence was prepared comprising publications from academic journals and grey literature accessed through bibliographic databases (Web of Science, Scopus, and CAB Abstracts), libraries, direct requests to relevant organisations and individuals, and citation tracking from past reviews. A screening process refined the evidence base to 226 studies within the UK. The systematic evidence map codes the content of each study against a comprehensive list comprising actors, drivers of or barriers to woodland creation, and outcomes. These are presented as a freely accessible, interactive online dashboard detailing sources of evidence. The systematic evidence map helps users navigate the evidence, demonstrating where the bulk of the evidence lies and, conversely, several evidence gaps where there is comparatively little evidence. The findings serve as a basis for dialogue with stakeholders to determine priorities for future primary research.

We describe experiences between 2018 and 2021 co-designing tree health policy options linked with the UK’s evolving land use policy post EU-Exit within the Future Farming and Countryside Programme. Policy makers, researchers and more than 250 land managers took part in a series of co-design engagements in a three-phase iterative co-design process that culminated in a new Tree Health Pilot. After defining the components of co-design, we describe how relationships between policy makers, researchers and land managers were built, the methods researchers introduced into the process to build capability and support participation, and the outcomes in terms of the key opportunities and challenges for policy co-design. We conclude that it is possible to move policy design beyond user focused research and into co-design. However, this relies on adequate time and resources required to build trust and fully engage all parties in a meaningful way, including the development of tools and techniques that include experimentation, different knowledge types, and moving from research and evidence collection into design. Having policy makers with participatory mindsets in the same space as land managers was important to facilitating active learning between all of those involved in the collective. Researchers played a critical role in the co-design, balancing the views and understandings of the policy community with those of the land manager community, facilitating learning, and selecting tools and techniques to make design options explicit. We conclude that policy co-design in the land-based and environmental sector is a real opportunity at an early stage of realisation, but the effectiveness and range of positive and negative outcomes and impacts will need to be evaluated in the future.

The values of forests have been extensively researched by focusing on general public perspectives with different frameworks used to categorise them. Studies have also explored forest manager values; however, there is limited evidence on the values they associate with specific tree species. Understanding more about managers’ values regarding a particular species is important when considering how they make decisions and might respond to tree pests and disease threats. In this study, we explored forest managers’ values regarding oak trees and the effects of a particular pest and disease risk known as Acute Oak Decline on these. This paper outlines the results from interviews with forest managers in England and a survey of private forest managers in Britain to capture the ways in which they value the oak trees they own, manage, or influence. Forest manager types included private owners of single or multiple properties, forestry professionals, businesses, and tenants. The results show that oaks were highly valued by forest managers as an iconic cultural species in the landscape and for their timber. Veteran and ancient oak trees were considered very important, and managers were more likely to spend time and resources attempting to conserve these oaks due to their perceived cultural value. Those who had trees that were suffering from Acute Oak Decline were also more likely to spend resources on them to save the trees or try to reduce the impact of the disease. Gaining a better understanding of forest managers’ attitudes towards protecting species they value is important as it has implications for their decision-making and management behaviours. It can also help to provide relevant bodies with information on how best to develop and communicate guidance and advice on monitoring and reporting disease symptoms, as well as managing oak tree health.

Forests are in the spotlight: they are expected to play a pivotal role in our response to society’s greatest challenges, such as the climate and biodiversity crises. Yet, the forests themselves, and the sector that manages them, face a range of interrelated threats and opportunities. Many of these are well understood, even if the solutions remain elusive. However, there are also emerging trends that are currently less widely appreciated. We report here the results of a horizon scan to identify developing issues likely to affect UK forest management within the next 50 years. These are issues that are presently under-recognized but have potential for significant impact across the sector and beyond. As the forest management sector naturally operates over long timescales, the importance of using good foresight is self-evident. We followed a tried-and-tested horizon scanning methodology involving a diverse Expert Panel to collate and prioritize a longlist of 180 issues. The top 15 issues identified are presented in the Graphical Abstract. The issues represent a diverse range of themes, within a spectrum of influences from environmental shocks and perturbations to changing political and socio-economic drivers, with complex emerging interactions between them. The most highly ranked issue was ‘Catastrophic forest ecosystem collapse’, reflecting agreement that not only is such collapse a likely prospect but it would also have huge implications across the sector and wider society. These and many of the other issues are large scale, with far-reaching implications. We must be careful to avoid inaction through being overwhelmed, or indeed to merely focus on ‘easy wins’ without considering broader ramifications. Our responses to each of the challenges and opportunities highlighted must be synergistic and coherent, involving landscape-scale planning. A more adaptive approach to forest management will be essential, encouraging continual innovation and learning. The 15 horizon scan issues presented here are a starting point on which to build further research, prompt debate and action, and develop evidence-based policy and practice. We hope that this stimulates greater recognition of how our forests and sector may need to change to be fit for the future. In some cases, these changes will need to be fundamental and momentous.

Forest and woodland owners and managers are generally perceived to be acting slowly in addressing environmental change by adapting their forestry practice. Diversification of tree species composition and stand structure is widely promoted as one adaptive approach to increasing the resilience of forests to climate change and other threats. Land manager behaviour is known to be affected by structural and psychological barriers to action. This study used data from a national survey and qualitative interviews among different types of forest owners and managers in the UK, including large- and small-scale woodland managers, to explore their intention to make changes to their forest management and the uptake of species diversification as an adaptation practice. The revised New Ecological Paradigm (NEP) was applied as a measure of worldview, which helped to explain some aspects of their decisions to take up diversification as an action to increase resilience. There were significant interactions between NEP and discredence-i.e. distrust in science or policy recommendations-and woodland size and the uptake of diversification. Many small-scale woodland managers hold strong ecological worldviews which can act against active adaptation because of a belief in the power of nature to adapt, or a mistrust of applying recommendations which might represent "doing the wrong thing". Research and policy processes that involve owners and managers are more likely to incorporate these climate change rationalities and adaptation logics. The framing, salience and robustness of climate change adaptation information emerges as important for all forest owners and managers and requires additional attention by scientists and policy makers.

Abstract A biocultural diversity approach integrates plant biology and germplasm dispersal processes with human cultural diversity. An increasing number of studies have identified cultural factors and ethnolinguistic barriers as the main drivers of the genetic diversity in crop plants. Little is known about how anthropogenic processes have affected the evolution of tree crops over the entire time scale of their interaction with humans. In Asia and the Mediterranean, common walnut (Juglans regia L.) and sweet chestnut (Castanea sativa Mill.) have been economically and culturally important crops for millennia; there, in ancient times, they were invested with symbolic and religious significance. In this study, we detected a partial geographic congruence between the ethno‐linguistic repartition of human communities, the distribution of major cognitive sets of word‐related terms, and the inferred genetic clusters of common walnut and sweet chestnut populations across Eurasia. Our data indicated that isolation by distance processes, landscape heterogeneity and cultural boundaries might have promoted simultaneously human language diversification and walnut/chestnut differentiation across the same geographic macro‐regions. Hotspots of common walnut and sweet chestnut genetic diversity were associated with areas of linguistic enrichment in the Himalayas, Trans‐Caucasus, and Pyrenees Mountains, where common walnuts and sweet chestnuts had sustained ties to human culture since the Early Bronze Age. Our multidisciplinary approach supported the indirect and direct role of humans in shaping walnut and chestnut diversity across Eurasia from the EBA (e.g., Persian Empire and Greek–Roman colonization) until the first evidence of active selection and clonal propagation by grafting of both species. Our findings highlighted the benefit of an efficient integration of the relevant cultural factors in the classical genome (G) × environmental (E) model and the urgency of a systematic application of the biocultural diversity concept in the reconstruction of the evolutionary history of tree species.

Invasive tree pests and diseases present some of the greatest global threats to forests, and the recent global acceleration in invasions has caused massive ecological damage 1, 2. Calls to improve biosecurity have, however, often lost out to economic arguments in favour of trade [3]. Human activities, such as trade, move organisms between continents, and interventions to reduce risk of introductions inevitably incur financial costs. No previous studies have attempted to estimate the full economic cost of a tree disease, and the economic imperative to improve biosecurity may have been underappreciated. We set out to estimate the cost of the dieback of ash, Fraxinus excelsior, caused by Hymenoscyphus fraxineus, in Great Britain, and investigate whether this may be the case [4].

Acute outbreaks of pests and disease are increasingly affecting tree populations around the world, causing widespread ecological effects. In Britain, ash dieback Hymenoscyphus fraxineus (Baral et al.) has severe impacts on common ash (Fraxinus excelsior L.) populations, and the emerald ash borer (Agrilus planipennis Fairmaire) is likely to add to the impact in future. This will cause significant changes to the character and functioning of many ecosystems. However, the nature of these changes and the best approach for conserving ecosystems after ash loss are not clear. We present a method to locate those areas most ecologically vulnerable to loss of a major tree species (common ash) and identify the resultant damage to distinctive ecosystem properties. This method uses the functional traits of species and their distributions to map the potential degree of change in traits across space and recommend management approaches to reduce the change. An analytic hierarchy process is used to score traits according to ecological importance. Our results indicate that in some areas of Britain, provision of ash-associated traits could be reduced by over 50% if all ash is lost. Certain woodland types, and trees outside woodlands, may be especially vulnerable to ash loss. However, compensatory growth by other species could halve this impact in the longer term. We offer management guidance for reducing ecosystem vulnerability to ash loss, including recommending appropriate alternative tree species to encourage through planting or management in particular areas and woodland types. Synthesis and applications. The method described in this paper allows spatially explicit assessment of species traits to be used in the restoration of ecosystems for the first time. We offer practical recommendations for the ash dieback outbreak in Britain to help conserve functional traits in ecosystems affected by the loss of ash. This technique is widely applicable to a range of restoration and conservation scenarios and represents a step forward in the use of functional traits in conservation.

AbstractHigh‐quality abundance data are expensive and time‐consuming to collect and often highly limited in availability. Nonetheless, accurate, high‐resolution abundance distributions are essential for many ecological applications ranging from species conservation to epidemiology. Producing models that can predict abundance well, with good resolution over large areas, has therefore been an important aim in ecology, but poses considerable challenges. We present a two‐stage approach to modeling abundance, combining two established techniques. First, we produce ensemble species distribution models (SDMs) of trees in Great Britain at a fine resolution, using much more common presence–absence data and key environmental variables. We then use random forest regression to predict abundance by linking the results of the SDMs to a much smaller amount of abundance data. We show that this method performs well in predicting the abundance of 20 of 25 tested British tree species, a group that is generally considered challenging for modeling distributions due to the strong influence of human activities. Maps of predicted tree abundance for the whole of Great Britain are provided at 1 km2 resolution. Abundance maps have a far wider variety of applications than presence‐only maps, and these maps should allow improvements to aspects of woodland management and conservation including analysis of habitats and ecosystem functioning, epidemiology, and disease management, providing a useful contribution to the protection of British trees. We also provide complete R scripts to facilitate application of the approach to other scenarios.

Common walnut (Juglans regia L) is an economically important species cultivated worldwide for its high-quality wood and nuts. It is generally accepted that after the last glaciation J. regia survived and grew in almost completely isolated stands in Asia, and that ancient humans dispersed walnuts across Asia and into new habitats via trade and cultural expansion. The history of walnut in Europe is a matter of debate, however. In this study, we estimated the genetic diversity and structure of 91 Eurasian walnut populations using 14 neutral microsatellites. By integrating fossil pollen, cultural, and historical data with population genetics, and approximate Bayesian analysis, we reconstructed the demographic history of walnut and its routes of dispersal across Europe. The genetic data confirmed the presence of walnut in glacial refugia in the Balkans and western Europe. We conclude that human-mediated admixture between Anatolian and Balkan walnut germplasm started in the Early Bronze Age, and between western Europe and the Balkans in eastern Europe during the Roman Empire. A population size expansion and subsequent decline in northeastern and western Europe was detected in the last five centuries. The actual distribution of walnut in Europe resulted from the combined effects of expansion/contraction from multiple refugia after the Last Glacial Maximum and its human exploitation over the last 5,000 years.

Rhododendron ponticum is a constant problem on Lundy. We present the results of an experiment investigating the lasting legacy of Rhododendron following clearance and the time needed for natural regeneration of the plants and fungi in cleared areas. These results are discussed with particular reference to their implications for management and clearance on Lundy and in other areas in the future.

Common walnut (Juglans regia L) is an economically important species cultivated worldwide for its wood and nuts. It is generally accepted that J. regia survived and grew spontaneously in almost completely isolated stands in its Asian native range after the Last Glacial Maximum. Despite its natural geographic isolation, J. regia evolved over many centuries under the influence of human management and exploitation. We evaluated the hypothesis that the current distribution of natural genetic resources of common walnut in Asia is, at least in part, the product of ancient anthropogenic dispersal, human cultural interactions, and afforestation. Genetic analysis combined with ethno-linguistic and historical data indicated that ancient trade routes such as the Persian Royal Road and Silk Road enabled long-distance dispersal of J. regia from Iran and Trans-Caucasus to Central Asia, and from Western to Eastern China. Ancient commerce also disrupted the local spatial genetic structure of autochthonous walnut populations between Tashkent and Samarkand (Central-Eastern Uzbekistan), where the northern and central routes of the Northern Silk Road converged. A significant association between ancient language phyla and the genetic structure of walnut populations is reported even after adjustment for geographic distances that could have affected both walnut gene flow and human commerce over the centuries. Beyond the economic importance of common walnut, our study delineates an alternative approach for understanding how the genetic resources of long-lived perennial tree species may be affected by the interaction of geography and human history.

Gabriel Hemery celebrates the 350th anniversary of John Evelyn's treatise on the science and practice of forestry.

The extent and provenance of the existing global knowledge base were qualified in relation to ten specific questions of priority to forestry research. The ten questions were derived from a participatory exercise; the Top Ten Questions for Forestry research (T10Q) completed in 2008. Analysis of the first-ranked question, relating to invasive species, pests and diseases, revealed a lower than expected volume of published European literature, compared with the other nine questions and overall database figures. Analysing the published scientific literature of relevance to the T10Q demonstrated a novel method of using bibliometrics to link stakeholder priorities with the existing knowledge base to provide a richer picture of the state of scientific evidence available for decision-making.
