🆕 The first stunning images from our groundbreaking #Biomass satellite mission have been released – they mark a major leap forward in our ability to understand how Earth’s forests are changing and exactly how they contribute to the global carbon cycle 🌳🌍

www.esa.int/Applications...
This image features part of Bolivia. This vibrant image was created using the radar instrument’s different polarisation channels, with each colour revealing distinct characteristics of the landscape. For instance, green hues mainly represent rainforest, red hues forested floodplains and wetlands, and blue–purple is indicative of grasslands, while black areas are rivers and lakes. The image spans approximately 90 km along the Biomass satellite's flight path (length) and 60 km across in width, with north oriented to the right.

This is also the last field campaign as part of @erc.europa.eu SPACETWIN. Excellent work by our @qforestlab.bsky.social field team Zane Cooper, Wout Cherlet and Wouter Van den Broeck. [4/4]

We have been using terrestrial laser scanning to acquire baseline structural data of trees within these dynamic forests. We will be back in the future to see how these forests have changed structurally over time. [3/4]

This new permanent plot network is led by @westsyduhie.bsky.social‬ Brendan Choat. The plot network will incorporate cutting-edge sensor technologies that allow for real-time ecological monitoring of fauna and flora (more info ➡️ bit.ly/43YfdI0). [2/4]

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]

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
Ring 2 of the EucFACE experiment, May 2025. Trees have finally returned to good health after a string of extreme events PhD students Wout and Zane from University of Ghent with TLS scanner at EucFACE

Later this month, we will move to sector Jeinimeni, where there is currently a large outbreak ongoing – completely defoliating trees. Video from earlier this week [4/4]

We are collecting terrestrial laser scanning data, spectral measurements of leaves, bark and understory and multispectral drone data. Not too much is known about these forests and these field measurements will result into a better understanding of these ecosystems. [3/4]

We are setting up 6 new permanent plots in the El Furioso sector of the National Park, supported by CONAF. These sites had different impacts of caterpillar disturbance over the last decade. [2/4]

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...

The TFE has been running since 2001. With the roof being taken off now, it becomes a recovery experiment. In collaboration with the University of Edinburgh (UK) and The Universidade Federal de Para & Museu Paraense Emilio Goeldi (Brazil). [2/2]

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!
