    Résumé : Abstract The translation of genetic gains into economic gains is important for evaluating the impact of using genetically improved forest reproductive material (FRM) in the forest sector. However, few studies based on European forests have been published to date. Here, we analyse the stand-level wood production and financial performance of planting genetically improved FRM in even-aged planted forests focusing on four European case studies with advanced breeding programme material and different management contexts: Scots pine (Pinus sylvestris L.) in southern Finland, central Sweden and central France, and maritime pine (Pinus pinaster Ait.) in southwestern France. The growth of improved stands was simulated using species-specific growth models by incorporating two levels of expected genetic gains (present and next generations of seed orchards, varying from 7 to 40 per cent depending on the breeding programme) into the estimated mean annual volume increment over a rotation (m3 ha−1 yr−1). For each level of genetic gain, we tested the plantation of improved FRM managed with two silvicultural scenarios (maintaining the standard baseline rotation and thinning regime vs shorter rotation through the earlier achievement of the recommended felling criteria) in comparison with the plantation of the reference unimproved material (absence of genetic gain) managed according to the standard silvicultural regime. The use of improved FRM resulted in a larger financial performance in terms of soil expectation value (SEV € ha−1, discount rate 3 per cent) than planting unimproved reference material in all case studies and silvicultural scenarios for different wood price contexts (SEV gain from +20 to +190 per cent depending on the genetic and silvicultural context). The challenges associated with the economic assessment of realized gains from genetically improved FRM are discussed. We argue that silvicultural guidelines should be adapted to the use of improved FRM in order to gain better financial performance and flexible silvicultural response of planted forests to future environmental and socio-economic changes.

    Résumé : The European natural resin extraction industry went through a period of deep crisis during the end of the last century. Public and Private initiatives have been taken in Spain, France and Portugal. The main initiatives implemented are presented in this study which was carried out as part of SustForest+ Project, funded by Interreg Sudoe and the European Regional Development Found (ERDF). First, the study consists in a description of the different production contexts in the world and the associated harvesting methods. This technical information is supplemented by economic data on the past and current resin market. This state of play makes it possible to formulate proposals concerning the evolution of the international resin market. Two scenarios are proposed, favorable or unfavorable to the development of resin production in Europe. The European potentialities of production are then estimated by cost-benefit analysis for each method in each European country, in order to know the profitability thresholds in different production contexts and thus to estimate the viability and sustainability of the various forest management systems designed to harvest resin in south west Europe.

    Résumé : Aim of study: Adaptation of silviculture in planted forest may help to mitigate damage due to biotic and abiotic hazards. However, compromises have to be found because it is not possible to minimize the risk from all hazards through application of a single forest management approach. The objective of this study was to improve a multi-criteria risk analysis (MCRA) method that makes it possible to rank forest management alternatives (FMAs) according to multiple risks. Material and Methods: We defined eight FMAs for maritime pine forests in France, Spain and Portugal. We used as the definition of risk the combination of hazard, susceptibility and exposure. Hazard level was estimated using archive data on occurrence and severity of damaging agents over the last few decades. Forest susceptibility to hazards was evaluated by experts who scored the effect on stand resistance of eleven silvicultural operations characterizing each FMA. Exposure was estimated as value at stake, which combined forest standing volume, simulated with forest growth models, and wood prices.Main Results: Using the PROMETHEE algorithm, we found that the overall ranking of FMAs was consistent across all countries, with short rotation plantations to produce pulpwood or energy wood were the least at risk. The ranking was mainly driven by forest values at stake. We found that by improving the accuracy of forest values exposed to damage, based on growth models and representative wood prices, the MCRA outcomes were more useful and realistic.Research highlights: Our methodology provides a relevant framework to design FMAs that would minimize risks while maintaining income.Keywords: Pinus pinaster; vulnerability; hazards; growth modelling; expert assessment; wood price; southwestern Europe.

    Résumé : To anticipate European climate scenarios for the end of the century, the REINFFORCE (RÉseau INFrastructure de recherche pour le suivi et l’adaptation des FORêts au Changement climatiquE) arboreta network was established. This data set contains data from in 10 sites, where 6 selected tree species are represented. This data allow to calculate survival and growth. This data will help to identify those species that are more tolerant of climate variation and those of which the growth and survival future climate might constrain.

  • Pötzelsberger E, Lapin K, Brundu G, et al. Mapping the patchy legislative landscape of non-native tree species in Europe. Forestry: An International Journal of Forest Research. 2020:cpaa009. Available at: Consulté juin 4, 2020.
    Résumé : Abstract Europe has a history rich in examples of successful and problematic introductions of trees with a native origin outside of Europe (non-native trees, NNT). Many international legal frameworks such as treaties and conventions and also the European Union have responded to the global concern about potential negative impacts of NNT that may become invasive in natural ecosystems. It is, however, national and regional legislation in particular that affects current and future management decisions in the forest sector and shapes the landscapes of Europe. We identified all relevant legal instruments regulating NNT, the different legal approaches and the regulatory intensity in 40 European countries (no microstates). Information on hard and effective soft law instruments were collected by means of a targeted questionnaire and consultation of international and national legislation information systems and databases. In total, 335 relevant legal instruments were in place in June/July 2019 to regulate the use of NNT in the investigated 116 geopolitical legal units (countries as well as sub-national regions with their own legislation). Countries and regions were empirically categorized according to ad hoc-defined legislation indicators. These indicators pay respect to the general bans on the introduction of non-native species, the generally allowed and prohibited NNT, approval mechanisms and specific areas or cases where NNT are restricted or prohibited. Our study revealed a very diverse landscape of legal frameworks across Europe, with a large variety of approaches to regulating NNT being pursued and the intensity of restriction ranging from very few restrictions on species choice and plantation surface area to the complete banning of NNT from forests. The main conclusion is that there is a clear need for more co-ordinated, science-based policies both at the local and international levels to enhance the advantages of NNT and mitigate potential negative effects.

  • Orazio C. O6.5 -Examples of trade-offs and multiple ecosystem services assessment in the integrated management of maritime pine landscapes. 2020. Available at: Consulté sans date.
    Résumé : Maritime pine forest being installed planting improved tree material after ploughing to produce mainly wood for industries is often perceived as an industrial forest providing only wood. On the last decade many studies demonstrated that the system is much more integrated than it appears. In past studies, we set up indicators to link the deadwood remaining from the management activities to the biodiversity, the mushroom picking and other externalities have been estimated in a short study of 2010. In addition, INTEGRAL project offered the opportunity to analyse possible trajectories of many ecosystem services depending on the political choices done afterthe storm. A recent project SUSTFOREST+ is exploring the options to combine resin and wood production diversifying the production function. Following the recommendation from the SIMWOOD handbook, projects such as T4effect analyse ecosystem services consequences of increasing stump harvesting or TREFFOR looking at opportunities to intensify wood production using pines in more agricultural landscapes. On the top of this integrated management analysis, the question of landscape organisation for a better resilience to the main risks was discussed in a project promoting integrated risk management (FORRISK) and has been implemented in a just ending project PLURIFOR establishing risk management plans

    Résumé : The world’s forests have never been more threatened by invasions of exotic pests and pathogens, whose causes and impacts are reinforced by global change. However, forest entomologists and pathologists have, for too long, worked independently, used different concepts and proposed specific management methods without recognising parallels and synergies between their respective fields. Instead, we advocate increased collaboration between these two scientific communities to improve the long-term health of forests. Our arguments are that the pathways of entry of exotic pests and pathogens are often the same and that insects and fungi often coexist in the same affected trees. Innovative methods for preventing invasions, early detection and identification of non-native species, modelling of their impact and spread and prevention of damage by increasing the resistance of ecosystems can be shared for the management of both pests and diseases. We, therefore, make recommendations to foster this convergence, proposing in particular the development of interdisciplinary research programmes, the development of generic tools or methods for pest and pathogen management and capacity building for the education and training of students, managers, decision-makers and citizens concerned with forest health.

  • Orazio C. Methodological issues and outputs of the REINFFORCE network - a unique transnational infrastructure of tree species arboreta for the adaptation of planted forests to future climate. 2019. Available at: Consulté sans date.
    Résumé : Predicting the future responses of productive forests and choosing the best-adapted regeneration material to climate change requires transnational infrastructures that provide evidence-based knowledge of the response of multiple tree species under a wide range of climatic conditions. This is why REINFFORCE was established as a unique network of demonstration sites to test the field performance and adaptation of 32 tree species from all over the world, including currently established and alternative productive species/provenances. The network made of 38 arboreta with common genetic material distributed along the European Atlantic arc (latitudes 37° to 58° N).This latitudinal gradient, covering a large diversity of climate and soil conditions, allows assessing the response of 120,000 tested trees from 176 provenances to current and anticipated future climatic conditions outside their current distribution range. We present methodological issues for the establishment, maintenance and coordination of the transnational network between the multiple partners, based on the common protocols and consolidated database for long-term monitoring and knowledge sharing. The latest outputs in methodological innovation include a harmonized field protocol for phenology assessment, height measurements with drone technology, and the use of the arboreta network as sentinels for emerging pests and diseases.The successful experience of the REINFFORCE network provides a strategic research platform for transnational cooperation and creates synergies with other research initiatives on forest adaptation to climate change. The latest research findings provides evidences and decision support for multiple forest stakeholders to increase the adaptation of the planted forests facing future climate uncertainty.

  • Correia A, Orazio C. Empirical evidences on the potential adaptive performance of alternative species under current and future climate: First results of the REINFFORCE arboreta network. 2019. Available at: Consulté sans date.
    Résumé : The forestry sector is strongly dependent on a very limited number of tree species whose long-term performance is increasingly threaten by climate change impacts. In order to sustain their productivity and mitigation capacity, the adaptation potential of our productive forests needs to be increased by diversifying the number of available species with better-adapted provenances. It is therefore crucial to provide forest owners and managers with empirical evidences on the potential performance of alternative species/provenances under a future climate. However, most of the current available information is originated from models that do not account for species/provenance plasticity, nor climatic conditions outside their current distribution. With the aim of reducing the uncertainty in the selection of adapted material, the REINFFORCE arboreta network was established along the European Atlantic arc (between latitudes 37° - 58° N) to test current and alternative species/provenances under contemporary and future climates. We present the field performance results of 33 different tree species under the wide gradient of climatic conditions covered by the 38 innovative network sites. We identified the climate drivers which better explain growth and survival performance, and the best and worst performing species under different climatic conditions. We also present a risk analysis for predicted performance for RCP 4.5 and 8.5 climate change scenarios. Our results will improve the knowledge about the site - climate matching of alternative planting species and the prediction of its behaviour in response to future climate, providing evidences for recommended plantation material with real adaptive capacity to climate change.

  • Branco M, Nunes P, Roques A, Fernandes MR, Orazio C, Jactel H. Urban trees facilitate the establishment of non-native forest insects. NeoBiota. 2019;52:25-46. Available at: Consulté novembre 13, 2019.
    Résumé : Cities, due to the presence of ports and airports and the high diversity of trees in streets, parks, and gardens, may play an important role for the introduction of invasive forest pests. We hypothesize that areas of urban forest facilitate the establishment of non-native forest pests. Based on scientific literature and a pan-European database on non-native species feeding on woody plants, we analysed where the first detections occurred in European countries. We collected site data for 137 first detections in Europe and 508 first European country-specific records. We also estimated the percentage of tree cover and suitable habitat (green areas with trees) in buffers around detection points. The large majority of first records (89% for first record in Europe and 88% for first records in a European country) were found in cities or suburban areas. Only 7% of the cases were in forests far from cities. The probability of occurrence decreased sharply with distance from the city. The probability to be detected in urban areas was higher for sap feeders, gall makers, and seed or fruit feeders (&gt;90%) than for bark and wood borers (81%). Detection sites in cities were highly diverse, including public parks, street trees, university campus, arboreta, zoos, and botanical gardens. The average proportion of suitable habitat was less than 10% in urban areas where the species were detected. Further, more than 72% of the cases occurred in sites with less than 20% of tree cover. Hotspots of first detection were identified along the coastal regions of the Mediterranean and Atlantic, and near industrial areas of central Europe. We conclude that urban trees are main facilitators for the establishment of non-native forest pests, and that cities should thus be intensely surveyed. Moreover, as urban areas are highly populated, the involvement of citizens is highly recommended.

  • Serrano-León H. The potential of investing in breeding forest material for a sustainable intensification of planted forests: management and micro-economic effects in 3 European study cases. 2019. Available at: Consulté sans date.
    Résumé : Given the limited land resources, increasing the productivity of planted forests and strengthening their management is essential to support a bioeconomy transition that can achieve the Sustainable Development Goals. One way to address the growing global demands for wood and fiber resources and enhance climate change mitigation is by investing in improved forest reproductive material. In addition to improving tree survival to adverse conditions, tree breeding enhances forest growth and resources quality, while reducing the required area for productive land. We analyze the effects of using genetically improved material in terms of silvicultural management, wood production and economic impact in three study cases in Europe with developed breeding programmes (maritime pine in French Landes, Scots pine in Central France, Scots pine in Finland). The growth development of improved stands was simulated assuming standard forest management guidelines and different genetic gain scenarios estimated for the available breeding material; while the financial performance was assessed considering the effect of different wood prices. The improved performance of breeding material resulted in substantially higher production and profitability in all cases, what can encourage forest owners to invest in forest management even in less productive sites. A higher financial stability against the price fluctuations in comparison with using unimproved material can be especially important to reduce the economic impact of unexpected changes in global wood markets. These potential gains from breeding material investment can play an important role on sustainable intensification of forest management under a context of global change.

  • Orazio C. Plantation's role in the forestry palette. EFI blog. 2019. Available at: Consulté sans date.
    Résumé : The recent EFI Scientific Seminar in Aberdeen was an opportunity to remind ourselves of the important role plantation forests play. The area of planted forests is increasing, both in the UK and worldwide, led by two main drivers: Offsetting carbon is the obvious one for countries like the UK that want to meet their goals for the Paris Agreement. In the UK’s case, it aims to plant about 15000 ha per year. A recent paper estimated the global reforestation potential at 0.9M ha, demonstrating that so far land availability is not an issue, even in EU. The challenge is then to plant the right tree in the right place with the appropriate technique. Increasing bioeconomy demand – more population, more substitution – is another strong driver. Even though global plantation area increases while forest areas decrease, the annual increase of 1.2% observed over the last decade is lower than the 2.4% needed to meet demand, which will double by 2050. A third driver of plantation expansion is climate change itself; with more disasters and diseases affecting forests, the replacement of large areas will require appropriate afforestation plans, but with high resilience. Genetic resources are key to success and will have to be characterised by much more than provenance tracking. Sustainability for all intensification measures such as fertilisation, mechanisation, and breeding will have to be assessed more precisely. Using non-native tree species Worldwide, 81 – 82% planted forests consist of native trees, but in Europe some large areas were planted with exotic species. About 150 Non Native Tree species (NNT) are present in Europe, but only a few (7 species) are widely used. Their productivity is on average 30% higher than native species in the same situation. Our current limited knowledge of the genetics of some NNT needs to be improved, so we can evaluate better their potential and eventual risk. In most cases, soils are improved by the introduction of NNT, but biodiversity is often lower in these stands – this together with a fear of invasiveness is leading to legal restriction of NNT in some European countries. Forestry is about people Polarisation around plantation topics is a (re?) emerging strong trend. Part of this comes from the feeling of companies or private owners making money – which is not an ecosystem service – from a common good without re-examining all the benefits and investments associated with this. Policy makers have a role to play as they can feed the polarisation or explore creative non-binary solutions based on scientific knowledge through policy tools such as regulation, financial incentives, and information/advice. A good example of politically driven depolarisation was the example of Scotland’s forest strategy design, which used participatory processes. Are foresters prepared enough for this dialogue, being so convinced that growing trees is good for the planet? Should we dedicate capacity building to developing know-how on conflict management related to plantations, or do we assume that explaining the least bad options will be enough? A landscape mosaic Historically plantations had a strong focus on restoration, or protection against erosion, flooding etc. Now they are used in more combined objectives (for example in Italy, where wood production runs alongside carbon sequestration and substitution roles). The diversity of actors and private (short-term high income) or public (long-term, maximum externalities) expectations are complementary from a societal perspective. Land use sharing with large range of intensification level is the best option. Today 7% of world forests provide 35-40% of timber. Plantations have their role in the landscape, reducing pressure on protected lands. Depending on how you design plantations (composition, structure) you can provide all types of ecosystem services, and it is important to use financial, regulatory and certification tools adequately to get the perfect mosaic. Plantations in the landscape can serve farming thanks to agroforestry, but also have a role in cities with peri-urban plantations or hydrology by saving watershades or support water recharging. In a context of global change there is a need for more guidance, standards, regulation, good practices, payment for actions… but also for real territory governance to make landscapes more resilient and make the most of plantations. Take home messages The land use impact of plantation forests is always much lower than agricultural land use. Science-informed decisions should guide integrated land use and resilient landscape design rather than polarised opinion. In Europe plantation forestry already plays a significant role in meeting environmental, economic and climate policies; going forward investments associated to good practices could enhance these contributions further. More data collection, better gene pool characterisations, more long term field trials and more research coordination, knowledge sharing and policy measures are needed to support the establishment, management and utilisation (markets) of planted forests. Social demand and climate Change are drivers for intensification and more flexible, complex and diverse plantation systems producing a larger set of ecosystem goods & services Adaptation/resilience is essential to secure mitigation, leading to high expectations for genetic resources. Even plantations with non-native species bring lots of colours to the forestry (and science) palette!

  • Orazio C, Yoga S. Silvalert: reporting forest damages in South West Europe. 2019. Available at: Consulté sans date.
    Résumé : Abstract Forest ecosystems occupy more than 30% of the land area in South West Europe. Forests in France, Portugal, and Spain are vulnerable to the increasing occurrence of biotic and abiotic hazards. Forest hazards can cause important and complex damages visible even beyond administrative borders. The risk of occurrence of multiple forest hazards has remained high for the past years requiring an on-going surveillance program by local forest authorities. Collecting field data on a regular basis is, however, cost-demanding. Participatory observations can help improve and diversify data collection. Silvalert is a mobile application that has been designed to report forest damages caused by diverse hazards. It is an open access application that can be downloaded after registration. The application has a simple user-friendly interface built to geolocate and capture photos of an encountered forest damage. Forest users can create offline reports and provide information on the type, extent, or severity of a forest damage. The information can later be uploaded to a server when internet coverage/signal is recovered. Reports are verified by the forest authorities who can use them as decision tools to determine for example, where to conduct extensive field surveillance. They are open access to the registered users who can visualize the type and extent of reported forest hazards which are currently prevailing at a European scale. Scientists can have an exhaustive access to all the reports and associated data.

  • Jactel H, Branco M. Urban trees facilitate the establishment of alien forest insects. 2019. Available at: Consulté sans date.
    Résumé : We investigate whether urban trees are main facilitators of establishment of alien forest insects. Based on scientific literature and a pan European database on alien invasive species we analysed where introduced forest insects were first detected in European countries. In total 508 first country-specific records were retrieved. We collected site location data, tree cover density and urban landscape suitable habitats (green areas with trees) in buffers (of 500 m radius) around detection points. Large majority of first records were found in urban or peri-urban areas (within 10km from city limits), varying from 81% for bark beetles and wood borers to 92 % for sap feeders and seed or fruit feeders. Only 7% of the cases were found in forests far from cities. Some reports were in rural areas and nurseries. Site types of first detection in cities were highly variable including, public parks, street trees, zoos and botanical gardens. More than 72% of the cases occurred in sites with less than 20% of tree cover proportion in term of surface. More than 50% of the cases in urban areas had less than 10% proportion of suitable habitat. We conclude that urban forest areas and urban trees are hotspots for the establishment of forest pests and that should be intensely surveyed.

    Résumé : In the context of planning restoration of the forest of Etang Sale (Reunion Island), an experimental programme led jointly by CIRAD (Forest Department) and Office National des Forets was set up in 1988 for choosing tree species to replace declining Casuarina equisetifolia. A detailed study considered the factors responsible for the decline of Casuarina equisetifolia, showing among others the increasing role of the attacks by an insect, Coelosterna scabrator [ Cerosterna scabrator]. Methods of preventive treatment are suggested. Among trees tested, several species were chosen: Acacia auriculiformis, Azadirachta indica, Eucalyptus camaldulensis, Eucalyptus citriodora, Grevillea robusta, Khaya senegalensis and Senna siamea, in particular because of their growth, low death rate and their resistance to hurricane winds. These tree species are now used in this reforestation site. Finally, an assessment of the effect of this operation upon the biodiversity was made using a published analysis of relationships between the forest habitat and the coastal bird communities of Reunion.
