New paper for the palaeofire fans!
Presenting the SahulCHAR collection, containing 687 sedimentary charcoal records from across Australia, New Guinea, and Aotearoa/New Zealand 🔥
Read it open access here: https://doi.org/10.5194/essd-17-2681-2025
This is the product of my final postdoc role - thank you to the many generous researchers who contributed their data!
New preprint out! 🔥 Using combined paleo-ecological and modeling methods, we uncover regional Holocene #wildfire dynamics in eastern #Siberia. Notably, our findings suggest potential human impacts as early as 5000 years ago - contrasting a common view of historically unmanaged forests 🌲
So far, any historical human impacts on fire regimes or traditional land use practices with relevance for wildfire were poorly acknowledged in international literature for eastern Siberia - despite clear indications from Indigenous communities, and former visitors leaving us with clear hints: For example, Georg W. Steller describes in the early 1700s his observation of common burning in forests near the Lena River. And in 1913, Fridtjof Nansen writes in his expedition notes about a long-standing habit of the Natives to burn old grasses near the Amur River. There is more to this 🔍
According to our study, fuel availability seems to be a key factor here. We discuss by example of the #Sakha how people may have reduced wildfire severity around their settlements since c. 800 years ago.

How was past #wildfire activity in eastern #Siberia and how did it relate to climate/vegetation/human activity? 🔥
Now out in E&G Quaternary Science Journal: a thesis abstract summarizing main findings from my dissertation. Big thanks to the German Quaternary Association (DEUQUA)!

Last chance to submit your abstract to come along to #EGU25 - if you have a burning interest in how fires and landscapes interact, consider our session - https://meetingorganizer.copernicus.org/EGU25/session/51797
Happy to see this great new study on future #boreal tree cover changes! 🌲

#Paleoecology offers a complementary perspective: We previously found that open woodlands in E-Siberia during the Early Holocene coincided with higher #wildfire activity, proposing a potential future "open woodland-fire feedback" 🔥
Reconstructing past wildfires and vegetation coverage furthermore led us to hypothesize that present-day, dense larch forests may still mediate the full extent of climate-driven fire regime intensification in this region. You can find our #paleofire study from #Siberia here:

Making #paleofire data #FAIR: Read our new report, published today in the new #PAGES Magazine, on integrating the Global Paleofire Database into the #Neotoma Paleoecology Database! This step will have benefits for data curators and users, but a lot of work is still ahead 🔥
I'm very pleased to be co-convening this proposed session at #EGU25 with @Geo_Juv and others - "CL1.2.12
Using proxy data, observations, and modeling to understand vegetation-wildfire-climate interactions during the past, present, and future." We look forward to your submissions, and catching up in Vienna!
Will you join the annual meeting of the German Society for #Geomorphology (#DGGM) in #Leipzig? If yes, let's have a chat!
I'll be there to present paleo-ecological evidence for impacts of #indigenous land use practices on #wildfires in eastern Siberia - and I'm happy to see that mine won't be the only #paleofire contribution! 🔥
Traditional land use practices in #Yakutia, eastern #Siberia, may have mediated #wildfires for centuries - until these practices were prohibited 🔥
See our evidence, obtained from lake sediments, tomorrow (Monday) at #EGU24 in session BG1.1! Looking forward to meet you there!

If you are interested in the chemical tracers of wildfires, and how those might vary with burn severity, check out our new #preprint https://www.authorea.com/doi/full/10.22541/au.170689252.26414470/v1
We leached wildfire ashes and soils from karst areas, so we can better understand the speleothem palaeofire proxy signal. Another team effort, with co-authors from #UNSW (👋 @Andbaker) #ANSTO, #UWA, and #GNSScience

The good folk at ANSTO did a nice summary of our speleothem palaeofire project over on Insta! Apparently, they did it last May, and I totally missed it 🤦🏻♀️

Sharing this open #paleofire #PhD position at the University of Aberdeen, UK 🔥
Apply Raman spectroscopy to #peatland cores and experimentally burned samples to reconstruct fire intensity changes throughout the past millennia- sounds like a great project!
Last week I had the chance to talk about Siberian #wildfires at #Hokkaido University's Arctic Research Center! 🔥❄️ One aim for my stay in #Sapporo is increasing collaboration of Japanese and German high latitudes research, and I'm very grateful for this opportunity - already made some new connections!
If #paleofire is your thing, e.g. the reconstruction of millennial-scale trends of fire intensity, find the talk abstract here:

@bluerehn I will for sure search once I have my new data, thanks for the suggestion 🤓😄 Forwarding this to the #paleofire group @paleofire
In a #paleofire review of studies in #Russia the authors describe a disorderly state of data in the Global Paleofire #Database. They advocate for a "Russian analogue of the database on paleofires". Personally, I like unifying instead of separating when it comes to databases. Also, due to the war and all it's consequences, such a database may not even be accessible from outside Russia. Any thoughts on this?

An exciting week is slowly coming to an end here at the Japan Geosciences Union Meeting 2023 in #Chiba, #Japan! 🗾
It is my first time attending #JpGU in person and an opportunity to learn a lot - about great scientific progress and efforts, about our planet and even our solar system neighbours!
Big thanks to the organizers of session M-IS01 on Northern #Eurasia for inviting my talk and having me co-chair parts of their session.
And Abby Riley, also at the Undergrad Research Symposium! Abby is using the thin sections of Miocene silicified charcoal to infer the composition of a forest destroyed by pyroclastic flow. So proud of my students! #HuskyResearch #stromberglab #paleofire
So proud of my undergrad mentees presenting at the Undergrad Research Symposium! Haley Brooks is conducting research on fossil charcoal morphometry as a means to understand what fuels were involved in ancient wildfires! #HuskyResearch #stromberglab #paleofire
