We use high-resolution remote sensing to understand how forests are responding to global environmental changes including logging, land management and climate change, addressing key issues in ecology and conversation.
“Conserving the world’s dwindling biological diversity is one of the most pressing issues facing humankind. I lead a research group that is actively engaged in addressing these issues, as well as tackling more fundamental ecological questions. Focusing on forest conservation and ecology, my research uses large databases and modern computational approaches, alongside traditional field approaches.”

Landmark British Ecological Society Report
Our head of group Professor David Coomes led the report’s Woodland Chapter. Nature has enormous potential to fight climate change and biodiversity loss in the UK. “For large-scale tree planting to be effective in capturing carbon, we will need to avoid species-rich grasslands, peat and other organic soils. Our focus should be on areas of low-quality grassland. However, this will reduce the UK’s capacity to produce meat and dairy, meaning a shift in our diets would be needed to avoid importing more of these products and offshoring our carbon footprint elsewhere.” Read more
CEOS biomass protocol has been endorsed
David Coomes was involved in an international team that developed protocols for the production and validation of satellite-based woody aboveground biomass products. The report documents accepted good practices in an open and transparent manner, that is scientifically defensible. It represents the current state of knowledge for satellite biomass remote sensing and includes a summary of current knowledge and data gaps toward operational validation of products at a global scale.

Unpicking the rhythms of the Amazon rainforest
James Ball‘s PhD project is part of a bigger effort to understand the forest’s productivity and rhythms, and to predict how the whole system will respond to climate change. Find out more about his last field trip to the Amazon rainforest of French Guiana on Nature.
River flow does not recover after planting trees
River flow is reduced in areas where forests have been planted and does not recover over time. Rivers in some regions can completely disappear within a decade. Read more
Tropical forests may never fully recover from logging
Continually logging and re-growing tropical forests to supply timber is reducing the levels of vital nutrients in the soil, which may limit future forest growth and recovery. Read more
Expedition finds tallest tree in the Amazon
New research has discovered the tallest known tree in the Amazon, towering above the previous record holder at a height of 88.5 metres. This giant could store as much carbon as an entire hectare of rainforest elsewhere in the Amazon. Read more

Aboveground biomass density models for NASA’s Global Ecosystem Dynamics Investigation (GEDI) lidar mission
NASA’s Global Ecosystem Dynamics Investigation (GEDI) is collecting spaceborne full waveform lidar data with a primary science goal of producing accurate estimates of forest aboveground biomass density (AGBD). This paper presents the development of the models used to create GEDI’s footprint-level (~25 m) AGBD (GEDI04_A) product, including a description of the datasets used and the procedure for final model…
Predicting leaf traits of temperate broadleaf deciduous trees from hyperspectral reflectance: can a general model be applied across a growing season?
Field spectroscopy is a powerful tool for monitoring leaf functional traits in situ, but it remains unclear whether universal statistical models can be developed to predict traits from spectral information, or whether re-calibration is necessary as conditions vary. In particular, multiple leaf traits vary simultaneously across growing seasons, and it is an open question whether…
Individual tree detection and crown segmentation based on metabolic theory from airborne laser scanning data
Laser scanning technology has enabled to study three-dimensional (3D) structures in forests. For example, airborne laser scanning (ALS) point cloud has been applied to detect individual trees and segment tree crowns. However, the accuracy of such approach remains a challenge because of the intersected crowns and complicated understories. We developed a metabolic theory-based algorithm for…
The motion of trees in the wind: a data synthesis
We have all seen trees swaying in the wind, but did you know that tree motion can teach us about ecology? Researchers have monitored tree motion for different purposes, from assessing wind damage risk to monitoring drought stress. Our new paper brings all this data together to study the differences between types of trees and test whether previous results generalize across a range of data sets. We computed a set of descriptive features from the…
Taking the pulse of Earth’s tropical forests using networks of highly distributed plots
Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here…
The impact of logging on vertical canopy structure across a gradient of tropical forest degradation intensity in Borneo
Forest degradation through logging is pervasive throughout the world’s tropical forests, leading to changes in the three-dimensional canopy structure that have profound consequences for wildlife, microclimate and ecosystem functioning. Quantifying these structural changes is fundamental to understanding the impact of degradation, but is challenging in dense, structurally complex forest canopies. We exploited discrete-return airborne LiDAR…
Recovery of logged forest fragments in a human-modified tropical landscape during the 2015-16 El Niño
It is unclear whether tropical forest fragments within plantation landscapes are resilient to drought. Here the authors analyse LiDAR and ground-based data from the 2015-16 El Niño event across a logging intensity gradient in Borneo. Although regenerating forests continued to grow, canopy height near oil palm plantations decreased, and a strong edge effect extended up…
Carbon flux and forest dynamics: Increased deadwood decomposition in tropical rainforest tree‐fall canopy gaps
Tree mortality rates are increasing within tropical rainforests as a result of global environmental change. When trees die, gaps are created in forest canopies and carbon is transferred from the living to deadwood pools. However, little is known about the effect of tree‐fall canopy gaps on the activity of decomposer communities and the rate of…
Monitoring ash dieback in British forests using hyperspectral remote sensing
Fungal ash dieback (Hymenoscyphus fraxineus) is posing an imminent threat to forest health in Europe. Using airborne hyperspectral imagery trained against 422 tree crowns of known species and ash dieback severity, we built PLS-DA and RF models that classified individual tree crowns (ITCs) into five species (>90% OA) and ash crowns into three disease severity…
