Quantifying, understanding and predicting forest growth in Switzerland
Forests world-wide are known as an important net carbon sink and are thus a key component of the terrestrial carbon cycle. However, carbon fluxes and storage vary regionally and with inter-annual to long-term environmental change. A higher frequency of drought events and other negative impacts on growth (increased autotrophic respiration and disturbances) are predicted to outweigh enhanced productivity as a result of increasing temperatures or CO2 and nitrogen fertilization. Existing models of forest growth dynamics include large uncertainties, which ramify and lead to divergence in forecasts how climate change will impact the future terrestrial carbon cycle. To reduce these uncertainties, it is necessary to extend and combine assessments of current observation networks using novel analytical approaches and data sources. Swiss forests are of particular interest: the climatic, pedologic and biogeographical conditions of Switzerland correspond closely with the European gradient, on a relatively small geographical scale.
WSL and its partners own a wealth of diverse data on forest growth and health in Switzerland. We plan to exploit this data treasure in our SwissForestLab project. Our aim is to estimate Swiss forest net ecosystem productivity (NEP) at monthly or seasonal resolution in order to link biomass changes over time with global drivers (climate, soils, landscapes, N deposition). We hypothesize that a combination of available high-quality long-term data sets provides an excellent data basis for a data-model-fusion approach within SwissForestLab. This activity is expected (a) to merge data with different temporal and spatial resolution so that they can be used more easily by SwissForestLab members, and (b) to provide a first visible result from SwissForestLab that will foster follow-up research projects focusing on different aspects of forest growth and development.
