I like big trees and I cannot lie. Great bit of work by @kimcalders.bsky.social @louiseterryn.bsky.social and colleagues using innovative climbing and scanning approach. Stunning illustration of tree structural and biodiversity complexity zslpublications.onlinelibrary.wiley.com/doi/full/10....

Integrating terrestrial and canopy laser scanning for comprehensive analysis of large old trees: Implications for single tree and biodiversity research

Canopy laser scanning (CLS) enhances 3D measurements of large trees by lifting laser scanners into the canopy. Combining CLS with terrestrial laser scanning improves point cloud precision, reduces oc...

🆕 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.

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]

@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...

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!
