Trois des espèces d’ongulés les plus fréquentes dans les Alpes - chamois, bouquetins et cerfs – prennent leurs quartiers à des altitudes plus élevées à la fin de l’été et en automne, en raison des changements climatiques. C’est ce que vient de montrer une équipe internationale de chercheurs sous la direction de l’Institut fédéral de recherches sur la forêt, la neige et le paysage WSL.
We demonstrate optimization pathways of forest management to mitigate climate change.
Plants are excellent indicators of environmental changes (incl. climate change), and we have used historical plant records previously to study (very) long-term vegetation changes in cold environments.

Les SLF-nivologues Michael Haugeneder et Dylan Reynolds parlent depuis les EUA de leur recherche en temps de changement climatique.
Future climate change will have drastic effects on mountain forests. We will analyse ancient DNA preserved in natural archives to reconstruct the impact of past rapid climate change on the neutral and adaptive genetic diversity of trees.
Climate change already affects snowfall and snow depth patterns in the Alps, and these changes will likely become more pronounced in the future.
Continuing climate change modifies the water supply and accentuates the pressure from competing water uses.
Less snow, less avalanches? We investigate the influence of climate change on avalanches by using climate projections to model future snow instability for selected representative sites in Switzerland.
Despite being an essential element of the biodiversity and climate change crisis, the feedback between biodiversity and climate remains an understudied subject in biodiversity and climate science. The project FeedBaCks will focus on this important interaction between the two disciplines.
Climate change could transform tundras from carbon sinks into a carbon source. New study with WSL participation published in Nature.
FORWARDS aims to develop, test, and implement a European Observatory that will supply timely and detailed information on European forests' vulnerability to climate change impacts, and provide knowledge to guide climate smart forestry
En compagnie de représentants des autorités groenlandaises et de scientifiques polaires suisses, Konrad Steffen, directeur du WSL, informera sur le terrain la présidente de la Confédération Doris Leuthard des conséquences des changements climatiques en Arctique.
The objective of the SwissPhenocam project is to develop and implement an automated phenology monitoring tool that will deliver added-value climate services regarding plant phenological responses to ongoing climate change and the carbon and water cycles.
The goal of this project is to take advantage of recently developed avalanche models and detection systems to setup a model framework for avalanche forecasting in Switzerland and to assess changes and uncertainties in avalanche hazard due to climate change.
A large network of research institutions collaborates within an EC-funded Network of Excellence to study the impacts of climate change on forest ecosystems from an evolutionary perspective.
Climate change threatens cities particularly through increasing frequency and intensity of heat waves, rainstorms and droughts. Green infrastructure is increasingly seen as a key measure for urban climate change adaptation. What potential does it really have and how should it be designed? How can the conflict between densification in growing cities and the development of green infrastructure be resolved? The lecture will present results from research projects at the Centre for Urban Ecology and Climate Adaptation at the Technical University of Munich.
Comment se portent les forêts et comment feront-elles face au changement climatique dans 15 ou 40 ans – dans ma ville ou ma région? Gestionnaires et propriétaires de forêts, responsables politiques, enseignant-e-s et personnes intéressées peuvent trouver des réponses en ligne via FORTE et FORTE Future, les nouveaux outils à guichet unique développés par le WSL dans le cadre du National Centre for Climate Services (NCCS).
Long-term research on the interactions between changes in land use and climate and their consequences regarding forest health and dynamic in the pine forests at low elevation of Central Alps
The WSL program Climate Change Impacts on Alpine Mass Movements (CCAMM) comprises projects covering a range of topics in natural hazards. Most investigations use models and thus require climate forcing data. The aim of this task is to provide meteorological forcings at the slope scale and in high temporal resolution.
Microclimate is a key factor influencing regeneration in forests. Particularly available light, water supply and temperature determine the success or failure of certain tree species. How will future climate change influence below-canopy microclimate and tree regeneration?
This initiative is aimed to establish a comprehensive European Forest Multifunctionality Monitoring System (EFMMS) that takes on the challenges posed by climate change and environmental stressors. The MoniFun project is a collaborative effort of 13 project partners from 11 European countries.
Die künstlerisch-wissenschaftliche Koproduktion ‚treelab. Experiencing the impact of climate change on trees in Europe‘ von der Eidg. Forschungsanstalt für Wald, Schnee und Landschaft WSL und der Zürcher Hochschule der Künste ZHdK wurde von STARTS Prize 2017 mit dem Anerkennungspreis bedacht.
GenTree aims at providing the European forestry sector with better knowledge, methods and tools for optimizing the management and sustainable use of forest genetic resources in Europe in the context of climate change and continuously evolving demands for forest products and services.
Supraglacial debris considerably alters the response of glaciers to changes in climate, yet debris-covered glaciers are notoriously difficult to delineate due to their fuzzy boundaries and spectral similarities to marginal moraines. Their surfaces are often characterized by supraglacial ponds and ex
The PAPPUS project aims to understand how decision makers influence the choice of plant assemblages and their management in different types of urban green spaces, and how their decisions in turn influence ecological and human benefits in a context of climate change and urban intensification.
With the MULTIBEF project, we aim at taking a holistic view to the study of B-EF relationships, and to investigate climate-change effects on complex B-EF relationships. To this end, we will take advantage of particular freshwater ecosystems tightly linked to forests: water-filled tree holes!
One of the most important questions of climate change impact research today is how glaciers are responding to global warming. ERC-funded, RAVEN aims to determine the role that debris-covered glaciers play in the water cycle of High Mountain Asia and better incorporate processes unique to debris-cove
The chemistry of soil solution and the soil water availability for plants have been monitored since 1997 in seven forest plots in Switzerland. This project, linked to the Swiss Long-term Forest Ecosystem Research project (LWF), aims to assess the soil response to atmospheric pollution (acidifying substances and nitrogen) and to climate change.
In this project we evaluate the effects of multiple combined perturbations on soil biodiversity and functioning. We evaluate perturbations related with climate change (drought and heat wave) and grassland management (fertiliser addition, pesticides, trampling, grazing effects, etc.). We hypothesise that combined perturbations will have synergistic effects with cascading negative effects on soil fauna and microbial communities biodiversity and functionality.
Glacier mass change has crucial impacts on hydrology, sea level rise, and climate change. Geodetic and glaciological mass balance observations so far have insufficient resolution to capture processes occurring on small spatial and/or short temporal scales. However, a permanent Terrestrial Laser Scanning (TLS) station adjacent to Hintereisferner (HEF, Ötztal Alps, Austria) provides daily Digital Elevation Models (DEMs), which allow closing spatiotemporal gaps in established glacier monitoring methods. An uncertainty assessment showed that smaller-scale processes, such as snow deposition and redistribution with a vertical spatial scale >0.10 m can be investigated with the TLS setup at HEF
Soils are not only the basis for the production of food and other raw materials, they also store and filter water, store carbon and harbour an overwhelming biodiversity. This multifunctionality emerges from complex interactions of small scale biological, physical and chemical processes. In this presentation we discuss how such processes can be represented in a systemic soil model that allows to predict the impact of soil management and climate change on soil functions and their dynamics at the scale of landscapes.
