The mission of LWF is to improve our understanding of how natural and anthropogenic stresses affect forests in the long term, and which risks for humans are involved. Consequently, we need to gain a more profound knowledge of the cause-effect relationships in the forest ecosystem and the underlying processes. The aims of LWF are:

  • to assess external anthropogenic and natural stresses (e.g., atmospheric deposition, climate)
  • to assess changes of relevant forest ecosystem components
  • to evaluate the influence of external stresses on forest ecosystems
  • to develop indicators of forest health
  • to analyse the risks under different stress scenarios

    Using a network of selected study sites, we monitor the long-term response of forest ecosystem components and processes to the most relevant stress factors. Our particular emphasis is on atmospheric deposition, the biogeochemical cycle, the climate, the soil, the ground vegetation and the trees.

    Leading questions:
    1. What parameters best characterise the condition of forest ecosystems in Switzerland?

    2. How is the condition of forest ecosystems in Switzerland changing, particularly in relation to global problems such as climatic change and air pollution?

    3. How far are models of forest ecosystem development and forest-climate interactions supported by data from integrated monitoring?

    4. What is the relative importance of anthropogenic- and naturally-induced changes in Swiss forest ecosystems?

    5. How have forest ecosystems in Switzerland developed in the past, and what were the main factors affecting their development?
