We have a #Tansley review out today @newphyt.bsky.social led by Becky Banbury Morgan in which we put forward a new framework that aims to explain how and why edge effects on forest structure vary across ecosystems and through time

Congratulations again and again and again to Dr. Ramon Melser! (@ramonmelser.bsky.social)

He joins the wall after successfully defending his thesis: “Enhanced assessment of boreal vegetation productivity using integrated satellite-derived datasets and analysis approaches.”

Work hard, play hard! 🌲✨ The #IRSSLab just wrapped up our annual summer retreat.

This week away gave lab members the chance to share research updates, pick up new skills from colleagues and guests, and, of course, enjoy some much-needed R&R!

Our new paper is out in Forest Ecology and Management!

Utilizing data from multiple forest inventory programs, we created 35 spatially complete estimates of forest structure and composition across the coastal regions of Alaska and British Columbia. 🌍🌐

treecbh: a new R package for crown base height (CBH) detection using aerial laser-scanned data in broad leaved forests 🌳

Diószegi et al. develop a workflow that automates and optimises CBH detection in already segmented individual trees.

🗞️ doi.org/10.1093/fore...
🔧 github.com/DijoG/treecbh
Framework of the treecbh R package: tree isolation (a), vertical cross-sectional K-means clustering (b), and the 2D kernel method (c). The detected crown base height is illustrated in the graph at the bottom right.

Members from the IRSS attended the #WIRED2025 symposium to present their research on overhead power lines across forested landscapes, as well as engage with industry and project participants.

Wonderful work from James (@jamesmcglade.bsky.social), Eliceo and Celine!

We tested ways to improve Canada’s National Forest Inventory (#NFI) estimates by integrating #Landsat derived #landcover data. Combining sample-based plots with wall-to-wall maps boosted estimation efficiency and helped track tree cover change. #OpenAccess #NTEMS
