Rapid polygenic adaptation in a wild population of ash trees under a novel fungal epidemic Open
Rapid evolution through small shifts in allele frequencies at thousands of loci is a long-standing neo-Darwinian prediction but is hard to characterize in the wild. European ash tree ( Fraxinus excelsior ) populations have recently come un…

The global spectrum of tree crown architecture Open
Trees can differ enormously in their crown architectural traits, such as the scaling relationships between tree height, crown width and stem diameter. Yet despite the importance of crown architecture in shaping the structure and function o…

Manual Labelling Artificially Inflates Deep Learning-Based Segmentation Performance on RGB Images of Closed Canopy: Validation Using TLS Open
Monitoring forest dynamics at an individual tree scale is essential for accurately assessing ecosystem responses to climate change, yet traditional methods relying on field-based forest inventories are labor-intensive and limited in spatia…

How many ways are there to measure a tree? – An experiment in cross-disciplinarity Open
This article takes a transdisciplinary approach to a relatively simple-sounding task – tree measuring. It asks the question, ‘How many ways are there to measure a tree?’, in order to provoke a discussion of our different ways of knowing. I…

Forest Productivity Decreases in Response to Recent Changes in Vegetation Structure and Climate in the Latitudinal Extremes of the European Continent Open
Aim Climate change is driving increasingly frequent and intense extreme climatic events, pushing many forests worldwide beyond their physiological thresholds. Despite the major role played by forests in the global carbon cycle, climate cha…

Benchmarking tree species classification from proximally sensed laser scanning data: Introducing the <span>FOR</span> ‐ <span>species20K</span> dataset Open
Proximally sensed laser scanning presents new opportunities for automated forest ecosystem data capture. However, a gap remains in deriving ecologically pertinent information, such as tree species, without additional ground data. Artificia…

Low-Cost Tree Crown Dieback Estimation Using Deep Learning-Based Segmentation Open
The global increase in observed forest dieback, characterised by the death of tree foliage, heralds widespread decline in forest ecosystems. This degradation causes significant changes to ecosystem services and functions, including habitat…

Common field measures and geometric assumptions of tree shape produce consistently biased estimates of tree and canopy structure in mixed Mediterranean forests Open
Crown shape and canopy structure are crucial determinants of tree and forest performance, and forest-climate interactions, but methods of quantifying these from field measurements are based on untested assumptions. Historically, measuremen…

The forgotten forests: Incorporating temperate peat‐forming wet woodlands as nature‐based solutions into policy and practice Open
Peat‐forming wet woodlands (forested wetlands) are naturally occurring carbon‐dense ecosystems that have considerable potential to form an important part of net zero woodland establishment and peatland strategies, as well as provide crucia…

<span>UAV</span> ‐derived greenness and within‐crown spatial patterning can detect ash dieback in individual trees Open
Ash Dieback (ADB) has been present in the UK since 2012 and is expected to kill up to 80% of UK ash trees. Detecting and quantifying the extent of ADB in individual tree crowns (ITCs), which is crucial to understanding resilience and resis…

Identifying direct deforestation drivers in Cameroon using deep learning and optical satellite data Open
Deforestation rates have been increasing in the Congo Basin in recent years, especially in Cameroon. To support actions to slow deforestation, Earth Observation (EO) has been used extensively to detect forest loss, but approaches to automa…

Forest-landscape dynamics across a climate gradient Open
Forests and landscapes are fundamentally interconnected, with geomorphic process being modulated by vegetation dynamics, which in turn is influenced by landscape form. Trees play a critical role in shaping landscapes by redistributing sedi…

Quantifying vegetation indices using terrestrial laser scanning: methodological complexities and ecological insights from a Mediterranean forest Open
Accurate measurement of vegetation density metrics including plant, wood and leaf area indices (PAI, WAI and LAI) is key to monitoring and modelling carbon storage and uptake in forests. Traditional passive sensor approaches, such as digit…

Fusion of European forest inventories with Sentinel-1 and Sentinel-2 data for improving scalability in estimating forest variables Open
Large scale forest inventory plot data are key to monitor forest ecosystems, but while they provide very detailed information at tree level they are limited in resolution in both space and through time. Earth Observation (EO) data offer th…
