The International Tree Mortality Network

Towards a global understanding of tree mortality - out in @newphyt.bsky.social a collaboration between 113 of our members exploring the potential to better understand tree death globally nph.onlinelibrary.wiley.com/doi/full/10....

Nice community meeting last week! @danielanemetschek.bsky.social gave us a sneak peak into the metadatabase (we cover >14.000 dendrometers already!), while @daniellecreek.bsky.social led the discussion on ongoing activities and priorities. Happy to see the community getting involved.

📢 Where can we find and secure/preserve historical #forest inventory/ #biodiversity data—and how can we make it usable for tomorrow's #research? 🌲🌳🌴🦋🦜🪲 I´m honored to be serving as the collection´s Guest Editor (along with my wonderful colleague Sheila Ward). We´re eager to read your submission!

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!

In Japan, valuable trees are relocated instead of cut down during development. Arborists use nemawashi, a technique combining horticultural knowledge and modern engineering, to prepare the trees for relocation.

🌳 Tree mortality in 🇫🇷 France rose 1.5–4× (2015–2023). 500k+ trees analysed; warmer winters & springs are top drivers. Even wet springs increase mortality risk via 'structural overshoot'. Seasonal climate combos matter more than single extremes. #forests #climatechange www.nature.com/articles/s41...

We relaunch our seminar series! Jordi Martinez-Vilalta will talk on the ‘Limits and opportunities in predicting drought-induced forest mortality’ 24 March 2026 at 15:00 UTC www.tree-mortality.net/seminars/

The future of Europe’s forest disturbance regimes– a thread. Tl, dr: Disturbances from wildfire, bark beetles & wind will continue to increase in the coming decades. Under unabated climate change disturbances could more than double by 2100. New paper out in @science.org doi.org/10.1126/scie...

We are hiring a postdoctoral researcher!🌲 🌳 🌍 📍Interested in boreal and temperate forest productivity and respiration? 💻 Like to work with large datasets, remote sensing and models? 🏔️ Love an alpine setting in a small town? Come and join us at KIT! Application details: t1p.de/qctj7

Drought and insects have killed an unprecedented number of Oregon’s Douglas fir trees during the last decade, costing billions in timber value, damaging infrastructure and ramping up wildfire danger. What is Douglas fir dieback? Where is it happening? What is being done? tinyurl.com/5n9amvx6

Australia’s trees are dying faster — not from fire, but from the stress of a warming, drying climate, weakening their role as vital carbon sinks. 🔗 theconversation.com/yes-forest-t... @bmedlyn.bsky.social @westernsydneyu.bsky.social @profchoat.bsky.social

Join us for an exciting ITMN Seminar: “Tiny leaks with deadly consequences” by Paulo Menezes July 24th at 3 pm (CEST). Register here: www.tree-mortality.net/seminars/

If you're waiting on a reply, a peer review, or other effort from me--please be patient. I urgently left to document a developing forest die-off event more intense than any I've seen. No obvious biotic agents, dead & dying include multiple Pinus & Juniperus, many Quercus, & shrubs. #WhatKillsTrees
