How do trees grow? What are the properties of forest soil? How do air pollution and climate change affect the forest? How do trees react to environmental conditions such as extreme drought? These are some of the questions we investigate in the Long-term Forest Ecosystem Research programme LWF.
In order to introduce and explain our research projects and over 30 measuring instruments, sensors and collectors to the general public, we have set up a test, training and demonstration facility in a forest stand near the WSL headquarters in Birmensdorf (fig. 1).
Besides training and demonstration, the third purpose of this facility is to test new measuring methods and instruments.
Find out here how we measure the pulse of the forest, which instruments we use and which research questions we are currently investigating.

The Long-term Forest Ecosystem Research Programme (LWF) examines how human-induced and natural stress factors affect forests in the short (yearly) and the long term (approx. 20 years). These include in particular air pollution and climate change. In order to be able to assess the risks associated with environmental changes and to simulate predictions, we need a deeper understanding of the processes involved.
The LWF carries out measurements on 19 sites all over Switzerland. On average, we record 25 million values per year, measured at one-minute intervals or up to hourly.
