Our research in the National Park Berchtesgaden - both in the field and in silico - was reported on by NANO.
The segment is in German and starts at minute 7:37

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...
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.

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...

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

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...

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
March 13, 2025 at 8:45 AM
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!🥳

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...
