Trade-offs between wood production and other ecosystem services (ES) are common. Understanding these trade-offs is a first step to ensure a balanced supply of ES from forests to society. Only few studies, however, consider the influence of the management and the ecological context such as the topography or the type of soils on these trade-offs. We, therefore, assessed the impacts of management and the ecological context on the supply of ES and their trade-offs. The assessment focused on six ES (wood production, carbon sequestration, flood and erosion control, clean water, recreation) based on an improved Burkhard’s matrix (Burkhard et al., 2009). We considered two types of forest with contrasting management and six types of ecological context ranging from productive soils to more restrictive sites and less productive soils. This matrix was applied on one hand, to map the supply of ES in four municipalities in Southern Belgium and on the other hand, to investigate the impacts of three scenarios (i.e. three different management strategies) on them. The improved Burkhard’s matrix showed that the differences among ES vary depending on the forest type and the ecological context. Trade-offs appeared only in some combinations of forest and soil type. The maps of ES allowed identifying the hot (synergies between ES) and cold (trade-offs between ES) spots in the territory. The changes in ES supply among the three scenarios and the current supply were quantified to identify the best management options. In conclusion, a forest is not like another in terms of the trade-offs among ES. Depending on their type, ecological context and management strategy, they provide different sets of ES. This heterogeneity is important to map to identify the hot and cold spots and to take actions in these specific areas (i.e. the cold spots) to ensure a balanced supply of ES. [less ▲]

Face au constat de la dégradation continue de la biosphère, le concept de services écosystémiques (i.e. ensemble des biens et services fournis par les écosystèmes ; SE) est de plus en plus mobilisé pour mettre en évidence la valeur des apports des écosystèmes à la vie humaine. Cette approche permet de révéler nos (inter)dépendances et interactions avec la nature, les coûts et bénéfices cachés de nos actions et de mettre en discussion les intérêts individuels et collectifs pour une gestion durable des écosystèmes. Dans ce contexte, une plateforme wallonne sur les services écosystémiques, nommée Wal-ES, a été mise en place en 2014. A l’interface entre le Service Public de Wallonie (SPW) et les universités wallonnes, Wal-ES vise à révéler l’importance du fonctionnement des écosystèmes pour intégrer l’approche des SE dans des outils d’aide à la décision. Financée seulement pendant une année, la plateforme n’a pu que mettre en place un cadre conceptuel et les bases communes devant servir ultérieurement à développer les outils d’aide à la décision. Toutefois, l’équipe scientifique a continué à mobiliser le concept dans deux projets de développement territorial. Le premier correspond à un aménagement foncier rural en Hesbaye où l’approche des SE a été mise en œuvre pour évaluer et développer la multifonctionnalité des paysages agricoles. Le second est le projet d'une première charte forestière sur quatre communes de la Grande Forêt de Saint-Hubert. Un diagnostic des services écosystémiques rendus par la forêt a été réalisé pour évaluer la répartition des services sur le territoire et préconiser des stratégies de gestion visant à en améliorer la fourniture.

La révélation des services écosystémiques (SE), c’est-à-dire l’ensemble des bienfaits que l’humanité tire de la nature (par exemple le bois, la pollinisation ou la récréation en nature), constitue une approche prometteuse pour mettre en évidence les multiples interactions entre l’environnement et les sociétés humaines ainsi qu’entre les acteurs. Elle révèle les coûts et bénéfices cachés des actions humaines et met en balance les intérêts individuels et collectifs pour une gestion durable, multifonctionnelle et résiliente des écosystèmes. Dans ce but, une plateforme wallonne sur les services écosystémiques (Wal-ES) a été mise en place pour incorporer cette approche dans les outils territoriaux d’aide à la décision (Wal-ES, 2016). L’approche des SE, développée par Wal-ES, a été appliquée au projet de « Première Charte forestière du territoire » mis en place par l’asbl Ressources Naturelles Développement8. Ce projet vise à donner à la « Grande forêt de Saint-Hubert » une place au sein du territoire tout en assurant sa multifonctionnalité au profit de l’ensemble des acteurs. Dans ce cadre, une cartographie des services rendus par cette forêt a été réalisée. Un niveau de 0 (fourniture minimale) à 6 (fourniture maximale) a été attribué à chaque service en fonction, d’une part, du type de forêt et d’autre part, du type de contexte écologique en différenciant les bons sols des sols peu fertiles ou contraignants. Cette cartographie a mis en évidence les zones pour lesquelles les services pouvaient être améliorés, c’est-à-dire celles de faibles fournitures en SE ou présentant un déséquilibre entre les intérêts individuels et collectifs. Afin d’évaluer l’impact de méthodes de gestion alternatives sur les services, trois scénarios ont été testés. Ce test a permis d’identifier les méthodes de gestion les plus appropriés pour assurer une fourniture diverse et équilibrée en services par la forêt, gage de sa multifonctionnalité et de sa durabilité.

Public awareness regarding key issues of biodiversity and ecosystem services gave rise to several policies aiming at their consideration in human activities. These policies led to a bunch of legal constraints and incentives that are as many tools to preserve and restore both biodiversity and ecosystem services. However, these tools are often activated in a punctual way, following private initiatives or opportunities and without much reflection about the stakes beyond the actors’ own interests. This results in scattered actions, a lack of cohesion in land planning and sometimes conflicts between stakeholders. Yet biodiversity and ecosystem services need a collaborative management, beyond the individualist approach, to ensure the success and continuity of launched projects. Two case studies illustrate the collaborative and structured application of diverse tools by and for a variety of stakeholders willing to respond to specific needs. The first case is biodiversity-oriented, as it concerns the conservation of Bromus grossus, a plant species listed in Annex II of the Natura 2000 “Habitat” directive, which only grows in agroecosystems. The second case study worked on land multi-functionality in three Walloon municipalities, using ecosystem services as a tool for a land consolidation plan. These two examples highlight: 1° the key actors for the launching and cohesion of the projects, 2° the strengthening steps for short and mid-term success and 3° some conflicting elements interfering with coherent development plans.

In Wallonia, a growing amount of projects on ecosystem services (ES) are conducted. These projects implement the ES concept at different spatial scales (ranging from the country scale to the plot scale), focus on some particular ES or consider all of them and finally, rely on one or multiple valuation types (i.e. biophysical, social and economic). With their multiple dimensions they feed each other with reflexions and methods. The aim of the stand is to give an overview of these ongoing projects taking place in Wallonia. Their similarities and common objectives will be highlighted on posters while their specificities will be presented by means of games, activities, quiz, etc. We hope to stimulate discussions and debates on our methods and results, to foster networking and knowledge exchange. Hereunder, we give a short overview of these projects to give hints on the diversity addressed by our stand. At the Belgian scale, BELBEES, a project funded by BELSPO, aims to identify the factors responsible for the decline of wild bees. Different hypotheses are tested, including the impact of land-use changes and the reduction of floral resources availability at geographical and temporal scales. The results will allow tracking historical community-level changes in pollination service at a biogeographical scale. Such initiative is a step forward in the perspective of ecosystem service mapping. In Wallonia, various projects on ES are underway: Wal-ES, a federating platform between the Walloon administrations and the scientists, aims to create and disseminate decision support tools based on the ecosystem services concept. In order to build the common core for these tools, Wal-ES defines a conceptual framework, an integrated ecosystem services valuation framework and a database regrouping all the information needed to assess ES in Wallonia. This platform helps to conduct a practical application of its integrated ES valuation framework to land planning at a local scale. This application aims to define a methodology for impact assessment of land-consolidation plans based on ES while testing it on a case study covering three municipalities in Wallonia. LIFE IN QUARRIES aims to develop biodiversity and ecosystem services in Walloon active quarries. One of its actions is the assessment and the monitoring of ES provided by a quarry regarding the restoration, maintenance and management of the nature undertaken during the project. BIOECOSYS project is focused on qualitative and quantitative assessment of ecosystem services provided by grasslands according to their management and their territorial context. The field study aims to determine production services under different soils and climatic conditions while the goal of the regional study is the mapping of several ES (production and regulation services). Other projects focus on a more regional or local scale: The first one studies the impact of forest cover on regulating services at the regional scale. This study investigates the impact of forest cover on hydrological services (i.e. water supply, water damage mitigation) in terms of quantity, timing and quality. The methods studying the impact of forest cover on water quality and carbon storage regulation service will be presented as well as the results of the impact of forest cover on the quantity and timing aspects. Secondly, a PhD project is looking at sown wildflower strips in agricultural fields. In the project, it is tested whether increasing the functional diversity of the flower mixtures used in wildflower strips can be a tool to optimize pollination and biodiversity support services. Another PhD research project is underway, willing to explore the relationships between biodiversity, functional diversity and the delivery of ecosystem services (pest control and pollination) in agricultural landscapes. This project aims at identifying the role of landscape and its ecological infrastructures (mainly Agro-Environment Schemes) on the species and functional traits composition of different arthropods assemblages. We will then link these diversity patterns to the provisioning of the ecosystem services of interest. Ongoing work also addresses agricultural practices, by analysing the contribution of agroecological farming systems to the delivery of ecosystem services. This project relies on an integrated valuation including both a biophysical and a social valuation. Focusing on the same fields as the above project, this one attempts to develop an innovative method to assess ecosystem services in agricultural fields by means of unmanned aerial vehicles (drones).

Within a species, the distance travelled by a particular diaspore depends on its morphology. In Poaceae, the presence of terminal sterile florets can lead to diaspore heteromorphism, which may influence dispersal. We tested the hypothesis that the presence of sterile florets favored dispersal in Bromus tectorum L., an invasive grass in the Western US. We used field and controlled experiments to study the dispersal of caryopses with and without sterile florets attached (respectively complex and simple diaspores), as well as pieces of inflorescence that detached from the mother plants. We considered both primary and secondary dispersal, as well as abiotic and biotic dispersal agents. The distance travelled by the diaspores and their attachment to animal fur were related to the presence and number of sterile florets. Abiotic agents moved diaspores over relatively short distances, both in terms of primary and secondary dispersal. A significant proportion of diaspores attached to fur, suggesting a potential for dispersal over longdistances. Complex diaspores were better dispersers than simple ones (and pieces of inflorescence), and this pattern was consistent across the study. However, among complex diaspores, the number of sterile florets had little or no influence. Considering primary and secondary dispersal by abiotic and biotic agents provided a general picture of the dispersal ecology of B. tectorum. For all the dispersal steps and dispersal agents we studied, the presence of sterile florets favored dispersal. These results highlight the functional significance of diaspore heteromorphism induced by floret sterility in the dispersal of Poaceae. [less ▲]
