The silent suffering of trees during the 2018 heatwave

New Nature Communication on the impact of the 2018 heatwave on trees growing across Central and Atlantic Europe published

Article by Ute Sass-Klaassen, Roberto L. Salomon, Georg von Arx, Kathy Steppe, Patrick Fonti, Roman Zweifel, Richard Peters, and Marcus Lindner

With the DenDrought2018 initiative, an international team of researchers is now able to tell a story about drought stress from the perception of 21 tree species across Europe. Results of their joint effort have now been published in Nature Communications under the title “The 2018 European heatwave led to stem dehydration but not to consistent growth reductions in forests” (doi: 10.1038/s41467-021-27579-9)

Let’s let the trees tell us – or: let the trees tell their story

by Patrick Fonti & Ute Sass-Klaassen
As humans and animals, trees also perceive their environment. However, differently than humans and animals, trees cannot escape unfavorable situation and thus have to have good mechanisms to face them to survive over decades and centennials. Our COST Action STReESS (Studying Tree Responses to extreme Events: a SynthesiS) focused the attention on understanding how trees respond to a changing environment and on how to collect, use and interpret this information to early and directly assess the impact of extreme climate events on forests. This approach, called the “tree-centered approach”, basically let the trees tell us how strong they perceived a given climatic extreme and how this is affecting them over the following years. With today’s current techniques, this can be monitored in near real time, opening also the possibility to create early-warning systems to assess the health status of our forests.
