DRYSOM assesses soil organic matter (SOM) to drought in a long-term irrigation experiment (Pfynwald). Responses range from a suppressed processing through microbial and faunal communities, decreases in carbon inputs from trees into soils, to shifts in soil carbon storage.
These SOM shifts have consequences for microbial communities and long-term carbon
This project will digitise the 100+ years worth of data that is stored in field note books, plot maps, hand-drawn root structures and crown maps etc.
They have proved to be very valuable for many WSL projects in connection with modelling
In this project, funded by the Swiss Agency for Development Cooperation (SDC / DEZA), we propose to apply large scale hazard indication mapping algorithms to the Himalayan province of Uttarakhand. Our goal is to identify unstable rock/ice masses and perform thermo-mechanical simulations – at the large-scale – to predict the danger of rock/ice avalanches, such as the recent event in Chamoli.
All of these events hence have disastrous consequences for people and infrastructures
Pine tree stand and forest site resilience after the severe 2017 wildfire on the slopes of Vesuvius, Italy
Since that date, even some seriously damaged pine stands have started to regenerate
The emergence of visible tree-stress symptoms caused by the emerald ash borer occurs only several years after its arrival and are hard to tell apart from those caused by soil drought. Here, we investigate the potential of reflectance spectroscopy as an early-warning screening tool.
Consequently, the early detection and containment of these species have gained importance
We want to explore a stable isotope tree-ring approach for analyzing physiological drought responses of trees. The results are expected to provide a novel diagnostic tool for understanding causes of tree decline.
Deuterium isotope ratios have been rarely applied in this context, but could be an

Although each test site will be small, the whole experiment will have an unprecedented
Tree-ring d13C variations are a valuable archive of climatic information. A novel laser-ablation isotope-ratio mass-spectrometer enables to study variations within a single tree ring. We therefore plan to determine the occurrence of dry and wet periods of the past with unprecedented resolution.

The goal of this project is to contribute to the evaluation of non-native tree species that could potentially mitigate mortality in our forests, through scalable drone-based phenotyping approaches and the assessment of mechanistic traits, such as phenological plasticity and drought stress-resistance

This project aims to holistically understand and quantify nitrogen fluxes across and within compartments to predict the effects of energy transition and environmental changes from other drivers and provide stakeholders and policymakers with informed possible outcomes of future scenarios.
Researchers have until now mainly focused onindividual compartments, thereby largely
