This project delivers soil and site related information for Swiss forests which are based mainly on measured values: (i) response of tree species relating to direct and indirect environmental variables, (ii) quantitative characterisation of species' ecological niche and (iii) soil ecological indicator values for forest plant species.
This project is part of the multidisciplinary CCES project BigLink (“Biosphere-Geosphere interactions: Linking climate change, weathering, soil formation and ecosystem evolution”). It studies the plant-soil-microbe interactions at early succession stages in the Damma glacier forefield occurring in response to limited nutrient availability.
The cycling of carbon and nitrogen are closely linked and thus, the increasing deposition of nitrogen very likely affects soil organic matter dynamics. We are adding 13C and 15N labeled litter from beech to soils and investigate how experimentally increased N inputs influence the fate of litter-derived C and N.
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.
The better understanding of the processes driving the dynamics of forest ecosystems requires the documentation of the constantly interacting compartments and fluxes of the biogeochemical cycle. Scientists study two fluxes (deposition of nutrients through precipitation and litterfall) and two compartments (foliage and ground vegetation).
