Climate change raises costs for European forestry - Nature Climate Change Natural disturbances, such as windthrows, pest outbreaks and wildfires, pose a major economic threat for the forestry sector. By coupling spatially explicit ecological and economic forest models, this study assesses the costs of natural disturbances under current and future climate conditions for all of Europe.

How expensive are natural disturbances for Europes forestry?

I'm super excited, that @natclimate.nature.com decided to publish a Research Briefing by @rupertseidl.bsky.social and me related to our recent paper on the cost of disturbances. Check it out here:

www.nature.com/articles/s41...

What is the cost of wildfire, windthrow and bark beetles for Europe’s forestry? We estimate that disturbances reduce Europe’s forest value by €115 bn, more than doubling to €247 bn under severe climate change. Led by @johannesmohr.bsky.social, out in @natclimate.nature.com doi.org/10.1038/s415...

What a pleasure to work on this important topic together with the great Félix Bastit under the perfect supervision of @rupertseidl.bsky.social and Thomas Knoke and with the great help of Marc Grünig, @wernerrammer.bsky.social , @corneliussenf.bsky.social and Dominik Thom. Thx for everything 🙏

We coupled forest growth, disturbance and economic models to simulate the interaction of forest productivity and disturbances under climate change… and there are big differences across Europe with C Europe being a particular hotspot of disturbance losses.

How expensive are 🪲💨🔥?! I can‘t believe it, but my 2nd PhD paper is finally published @natclimate.nature.com! Disturbances lower the economic value of Europes 🌲 by 29%... Climate change will increase it to up to 42%! (Now imagine a company looses 42% of its value…) doi.org/10.1038/s41558-025-02408-9

Come work with us! We are looking to fill a PhD (mountain forest management) and PostDoc position (forest adaptive capacity, w/ @juditlecinadiaz.bsky.social). We'd be happy to have you as part of our dynamic team!

Taylor’s law predicts unprecedented pulses of forest disturbance under global change - Nature Communications Large pulses of disturbance have been observed globally in response to climate change. Using Taylor’s Law, the authors show that those pulses were not unpredictable but expected given a strong scaling...

As the mean rate of forest disturbance is increasing, so does its temporal variance. Proof that Taylor's law also applies to disturbance ecology, and a warning of more severe future extremes. Paper led by @corneliussenf.bsky.social w/ @tommaso-jucker.bsky.social www.nature.com/articles/s41...

We are offering a new PhD position in our lab! You will study the impacts of forest disturbance and fragmentation on microclimate and forest regeneration, together with @katjakowalski.bsky.social.
Applicants from diverse backgrounds encouraged!

Could setting forest areas aside for conservation lead to more disturbances?🌲

Analysis of 314 pairs of managed & set-aside forests across Germany found no increase in disturbance rates in forest reserves. In fact, set-aside areas had fewer disturbances 🌏 🧪

Two inspiring days of discussions to better understand forests' adaptive capacity to disturbances! 🌳🔥🪲💨
Grateful for the inspiring group, the motivation, and the ideas we exchanged!
Thanks to @dfg.de for funding and to @edfm-tum.bsky.social for being part of the journey. Excited for what's ahead! 🚀

#SmartForest2025 started with a full house and a fantastic key note of @rupertseidl.bsky.social! Looking forward to all the discussions in the next days

The last signs are in place, and we're super excited for our #SmartForest2025 conference. Over the next two days, we'll discuss new smart tools and technologies to support forest science and management with both researchers and practitioners. Stay tuned and reach out if you're joining!🥳

Microclimate temperature effects propagate across scales in forest ecosystems - Landscape Ecology Context Forest canopies shape subcanopy environments, affecting biodiversity and ecosystem processes. Empirical forest microclimate studies are often restricted to local scales and short-term effects,...

iLand is the first forest landscape model to explicitly simulate forest microclimate. Why? Because microclimate effects propagate across scales and influence important processes such as decomposition, regeneration and bark beetle development. Read more in Braziunas et al. doi.org/10.1007/s109...

We are hiring! We're looking to fill a PostDoc position on social-ecological systems. Are you excited about the spatio-temporal dynamics of coupled human and natural mountain systems? Then come join us, and work in a wonderful & diverse team + beautiful environment!
