SwissForestLab is an infrastructure network and a research platform. By tapping into synergies from the expertise in forest research in Switzerland, we promote cooperative research for a deeper understanding of the functioning, resistance and resilience of forest ecosystems.

Bark beetles destroyed more than 1.4 million m3 of spruce wood in 2020. Beetle infestation is expected to remain high in 2021. (in German)

A high level of biodiversity is important for forest management. The more diverse a forest is, the better it can cope with external influences.

The Swiss stone pine may be unable to adapt fast enough to climate change, a genetic study finds, and could become locally extinct.

The Sandoz Family Foundation Programme for Academic Promotion has awarded Charlotte Grossiord at EPFL and WSL a two-year renewable grant.

The new State of Europe's Forests 2020 report, featuring WSL data, highlights the many distinctive aspects of Swiss forests.

Today, Europe's forests must perform many functions at once. Combining timber use with biodiversity promotion covers two key functions.

In the summer of 2018, many beeches changed leaf colour prematurely and reduced their growth, a study at 75 NFI sites reveals.

Swiss ecosystems are heavily polluted and reduction targets have not been met. This is revealed in a SCNAT factsheet with WSL co-authors.

With the FOEN, 20 cantons and forestry enterprises, WSL is creating 57 experimental plantations to study the climate tolerance of 18 tree species.

A study claims that forests should not be thoroughly cleared after storms or forest fires.
