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.



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.

Auf dem Totholz, das 2003 nach dem Waldbrand in Leuk liegengelassen wurde, leben heute viele spezialisierten Pflanzen und Insekten.

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

Trees throughout central Europe lost their foliage prematurely in the dry summer of 2018. WSL calculations show where and how intensely. contains over 2800 articles in four languages on forests. The new design is optimised for mobile devices and offers new features.

Lötschental study: When water is scarce, coniferous trees stop their wood growth despite the fact that they produce a lot of carbon.

Beech trees become stressed in dry summers – but not everywhere. If they find water reserves deep in the soil, their crown remains green.

With topics ranging from insect mortality to environmental policy, the research initiative "Blue Green Biodiversity" presents its first 13 projects.

How heavily are soils in Europe contaminated with radioactive caesium and plutonium? A Swiss-led international study provides a new map.

While biodiversity is shrinking globally, there may be different trends locally, a large-scale study with WSL participation shows.
