Did a tree die or suffer severe damage while your dendrometer was recording? 🌳🪾 In our first member-led data call, @pascal-schneider.bsky.social from @wslresearch.bsky.social is pooling such records to study tree-mortality patterns. Learn more and fill in the survey here: forms.gle/azsjfGrzUL9o...

Dendrometer time series from dying or severely damaged trees
This survey supports a joint study of whether dendrometer time series can provide consistent indicators of declining tree resilience and early warning signals for severe damage or tree mortality. Bec...

What are dendrometers and why do we need a global dendrometer network? 💥Our first GDN paper is out! We document how it all started with a meeting in Norway, and outline some of the great potential that lies in creating a global community. Read: doi.org/10.1093/tree... Join: globaldendro.org

Early defoliation, leaf browning and wilting and shedding of green leaves in Switzerland (Jura) and Southern Germany (Black Forest) - beech but also cherry and maple affected - heat and drought stress - and no rain forecasted for the next weeks. This is not unexpected - this is climate change!

Warm, wet springs may raise tree death risk, not just drought. French forest data indicate favorable early growth can leave some trees, especially tall ones, more vulnerable when later dry conditions arrive. doi.org/hb9nzf

Why Europe's trees are dying
In Europe, trees are increasingly dying prematurely. A new study by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) on French forests now shows that it is not only drought but also unusually warm or wet springs that increase the risk—even ideal growing conditions can prove fatal later on.

🌳How close are tropical forests to their photosynthetic limit? Our new paper highlights the vulnerability of these ecosystems to further warming and the importance of accurately representing canopy temperature. www.pnas.org/doi/10.1073/... @wslresearch.bsky.social

🍁 Trees in Europe are increasingly dying prematurely. A new WSL study on French #forests now shows that it is not only extremely dry summers but #climate anomalies in general that are driving tree mortality – particularly warm and wet springs: www.wsl.ch/en/news/why-... @lsce-ipsl.bsky.social 🌍

Why Europe’s trees are dying
Deviations from the usual climate are causing trees to die prematurely. Even favourable growing conditions can have a negative impact.

I agree - structurally complex, biodiverse forests are desirable. Poor structure is largely a legacy of centuries of production-oriented management. But I’d distinguish ungulate browsing from insect herbivory; the latter is more often framed as “pests.”

🙏 For me, this paper is a real milestone. I’m proud to see it published and grateful to all collaborators who made it possible: Agnès Pellissier-Tanon, Chuanlong Zhou, @ciais-philippe.bsky.social, Christian Piedallu, @albavianasoto.bsky.social, and @arthurobuntspecht.bsky.social!

🌲 This matters for how we monitor and manage forests. If mortality is driven by climate sequences, not just one dry summer, we need to think about species choice, stand density, and recovery conditions across the whole year.

🌱 One surprising result: “good” spring conditions can sometimes backfire. Warm, wet springs may promote rapid canopy growth, increasing water demand and making some trees more vulnerable if drought arrives later.

Pascal Schneider @pascal-schneider.bsky.social · 29/06/2026
📈 The main drivers were tree size, competition, and seasonal climate anomalies. Warmer winters and springs, warmer summers, drought patterns, and recovery conditions all mattered differently depending on species and context.

Pascal Schneider @pascal-schneider.bsky.social · 29/06/2026
🔎 We analysed >500,000 trees from the French National Forest Inventory (2015-2023), covering 52 species and a wide range of climates. Using ensemble modelling and explainable machine learning, we looked for the strongest signals behind mortality risk.

🌦️🌳 Why are more trees dying in European forests? Extreme summer droughts are definitely part of the story, but our new paper shows that tree mortality is shaped by climate variability across seasons, not by single extreme events alone. www.nature.com/articles/s41...

We show that plants align their optimal photosynthesis temperature with average growth temperatures! We can model this thermal acclimation across species and biomes without relying on plant functional types. All ready for improving model realism and future projections. 🌿📈 doi.org/10.1029/2024...

Analyzing data from over 500'000 trees, we found that warmer, wetter springs can increase mortality, likely due to rapid structural canopy growth (“overshoot”), pest proliferation, and disrupted phenology. Different drought types and warmer winters also play a key role. 🌦️🌳 doi.org/10.5194/egus...

🎉 Excited to share two major milestones of this week! 📢 At #EGU25, I presented our work showing that climate change is reshaping seasonal patterns, it’s not just hotter summers that matter! 📝 At the same time, our new open-access paper in #JAMES @agu.org came out! 🧵👇

How does photosynthesis respond to changing temperatures? In the paper led by Pascal Schneider, we show that the thermal acclimation of photosynthesis can be modelled without making assumptions about plant functional types - ready for adoption in ESMs agupubs.onlinelibrary.wiley.com/doi/10.1029/...
