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 LiDARContinue reading “The impact of logging on vertical canopy structure across a gradient of tropical forest degradation intensity in Borneo”

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 upContinue reading “Recovery of logged forest fragments in a human-modified tropical landscape during the 2015-16 El Niño”

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 ofContinue reading “Carbon flux and forest dynamics: Increased deadwood decomposition in tropical rainforest tree‐fall canopy gaps”

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 severityContinue reading “Monitoring ash dieback in British forests using hyperspectral remote sensing”

Riparian buffers act as microclimatic refugia in oil palm landscapes

There is growing interest in the ecological value of set‐aside habitats around rivers in tropical agriculture. These riparian buffers typically comprise forest or other non‐production habitat, and are established to maintain water quality and hydrological processes, while also supporting biodiversity, ecosystem function and landscape connectivity. We investigated the capacity for riparian buffers to act asContinue reading “Riparian buffers act as microclimatic refugia in oil palm landscapes”

Resilience of Spanish forests to recent droughts and climate change

Time-series of canopy greenness derived from satellite imagery can beanalysed alongside environmental factors, species composition andmanagement regimes, to better understand forest resilience to drought.In Spain, forests are on average greening despite drying trends. Thisresilience manifests in the short-term with native species activatingdrought tolerance and avoidance mechanisms observable from space (i.e.losing and gaining little greenness likeContinue reading “Resilience of Spanish forests to recent droughts and climate change”

Standardizing Ecosystem Morphological Traits from 3D Information Sources

3D-imaging technologies provide measurements of terrestrial and aquatic ecosystems’ structure, key for biodiversity studies. However, the practical use of these observations globally faces practical challenges. First, available 3D data are geographically biased, with significant gaps in the tropics. Second, no data source provides, by itself, global coverage at a suitable temporal recurrence. Thus, global monitoringContinue reading “Standardizing Ecosystem Morphological Traits from 3D Information Sources”

Protecting biodiversity and economic returns in resource‐rich tropical forests

In pursuit of socioeconomic development, many countries are expanding oil and mineral extraction into tropical forests. These activities seed access to remote, biologically rich areas, thereby endangering global biodiversity. Here we demonstrate that conservation solutions that effectively balance the protection of biodiversity and economic revenues are possible in biologically valuable regions. Using spatial data onContinue reading “Protecting biodiversity and economic returns in resource‐rich tropical forests”
