SLF researchers are not drinking tea for scientific purposes, but burying it in the ground. Within the framework of an international project, scientists are investigating how tea decomposes in mountain soils. Their aim is to improve our understanding of the CO2 cycle.
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?
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.
Ground vegetation is a powerful bio-indicator of the environment. The project aims at discriminating the various factors which may influence the dynamics of ground vegetation. Emphasis is being given to the role of nitrogen.
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).
It is important to have good information on the condition of the trees in the plots. Therefore scientists determine the relationships between crown condition and a number of environmental parameters.
