How to better understand droughts, fires and logging impacts on forests? ERC grantee Kim Calders builds digital twin forests using 3D laser scanning and satellite data. This can help improve climate models and forecasts of forest carbon dynamics 👉 bit.ly/4dstaT2 @kimcalders.bsky.social

New paper by Wout Cherlet & @qforestlab.bsky.social team led by @kimcalders.bsky.social, comparing tree extraction methods from TLS data. TL;DR it's hard to automate, ecosystem dependent & parametric approaches currently outperform DL www.sciencedirect.com/science/arti...

Benchmarking tree instance segmentation of terrestrial laser scanning point clouds

Terrestrial laser scanning (TLS) has revolutionized forest measurement techniques by providing detailed three-dimensional (3D) point cloud data that c…

The most well-know use-case of optical fibres is internet. We show that it actually allows us to measure microclimate temperatures at the ultra-high resolution of 25 cm! Since these fibres can be very long, up to 30 km (!), this novel means of environmental monitoring seems super promising.

Our campaign in the Blue Mountains is coming to an end. Since late April, we have been scanning several plots covering different vegetation types (33 done currently) within the Blue Mountains Hub for Ecology & Conservation. [1/4]

Sensors, scientists and sunshine. Thanks for the great Strucnet vegetation structural dynamics meeting @kimcalders.bsky.social.

Strucnet meeting organised by @kimcalders.bsky.social very much fun!

The #EucFACE canopy has finally recovered from the 19-20 drought and the 21-22 floods. Beautiful time for new Lidar scans! @westsyduhie.bsky.social @kimcalders.bsky.social

Job Alert - Come work with us at @qforestlab.bsky.social! I'm hiring a postdoctoral fellow in vegetation remote sensing and radiative transfer to work on my @erc.europa.eu SPACETWIN project (spacetwin.ugent.be). More info ➡️ www.ugent.be/en/work/scie... Deadline: March 7

We are currently in Patagonia for our @ercresearch.bsky.social project #SPACETWIN, looking at the impact of caterpillar (Ormiscodes amphimone) disturbance on the Nothofagus forests. This is a @qforestlab.bsky.social collaboration with the team of Roberto O. Chávez from PUCV in Valparaíso [1/4]

@qforestlab.bsky.social There are so many leaf-wood separation algorithms, don't know how to choose? Our latest work (from @qforestlab.bsky.social ) has addressed this issue by providing a robust evaluation framework. Interested? please check our paper: authors.elsevier.com/a/1kKNW7qzT3...

Wouter & Wout from @qforestlab.bsky.social are currently collecting TLS data at the Caxiuanã through-fall exclusion (TFE) experiment for our #ERC SPACETWIN working with our Brazilian collaborators and Patrick Meir. Continuing the TLS time-series that was initiated by @matdisney.bsky.social [1/2]

Important finding for impact modelers by @kornhuber.bsky.social et al.: Climatic extremes change faster/ more severely than anticipated by climate models. The consequences anticipated with impact models (based on climate model-driven forcings) might thus be conservative. www.pnas.org/doi/10.1073/...

The first month of our field campaign in the Queensland Permanent Rainforest Plots (@QPRPaus - ) has been a success with 6 plots already completed and 10 more to go in the coming weeks! [1/5]

It was great having Maurice Leponce give a guest lecture in our BSc course on Ecology, covering Tropical forest biodiversity: large-scale inventories, canopy access, and the role of natural history museums. Great inspiration for our students!

Experimental work on nondestructive monitoring of the dielectric permittivity dynamics of trees for @ERC_Research SPACETWIN with the installation of 2 wood penetrating radars. In collaboration with François Demontoux & Ludovic Villard.

Lathamus Keep, a Tasmanian giant Eucalyptus globulus (+80 m tall) in the Huon Valley scanned by terrestrial and canopy laser scanning. At 8 m high, it’s diameter is still an astonishing 3 m! View it in 3D here: w. @TerraLuma @l_hambrecht @BarbaraDhont

Vacancy! Join our team as a postdoctoral fellow (2yr position) on our newly funded @FWOVlaanderen project with @LouiseTerrynn and @shaunlevick! Info: Apply by Feb 9:

What a great two weeks in Tasmania with @TerraLuma and @l_hambrecht mapping giant and old trees for @ERC_Research SPACETWIN. We managed to scan 10 giants (with some well over >80m in height).

I have arrived in Big Tree State Tasmania! Working with @UTAS_ @TerraLuma on giant tree mapping for @ERC_Research SPACETWIN, with help from @CorigJan, @l_hambrecht & the tree projects. More soon!

The first leg of my Australian fieldwork trip was a success with a range of benchmark scans covering various forest structures with our RIEGL TLS and the autonomous LEAF scanners from ESS Darius Culvenor. Glad to have some hands-on training for LEAF installment from Darius!
