How the dry summer of 2018 affected forest trees is revealed by Europe-wide measurements of the fluctuations of tree trunks.

Two new user-friendly online tools display comprehensive information about forests and the services they provide, now and in the future.

In addition to high soil moisture and air humidity, the day length is particularly decisive. The length of the growing season is insignificant.

How genome analyses can help us to understand the forest ecosystem and adapt it to climate change was the subject of a conference at WSL.

This year's summer school focused on forest monitoring and was attended by 24 enthusiastic students from all over the world.

Researchers use spectral data from drone photos to reveal the health condition of trees.

A long-term study shows that dry periods hit spruce and fir forests hard, but targeted measures can increase their resilience.

Low-branched  fallen trees, now heavily decomposed, in a part of the Bödmerenwald where Storm Vivian brought down many trees in 1990.

The Bödmerenwald near Muotathal has seen a significant increase in wood volume, dead wood and small habitats for insects and fungi.

Tree pests are on the increase in Switzerland. Researchers at the WSL Plant Protection Laboratory are on their trail. Read more in Diagonal.
