Correction factors can overcompensate log-transformation bias in allometric biomass models
Research paper Key message Fitting allometric biomass models using ln-ln transformation approach can produce biased estimates, as in certain conditions correction factors were shown to overcompensate the back transformation bias. However, weighted nonlinear regression approach consistently provided

Estimating the age of Eucalyptus plantations using monthly Harmonized Landsat–Sentinel imagery and a LandTrendr-based workflow
Research paper Key message Using monthly Harmonized Landsat–Sentinel imagery and an adapted LandTrendr-based workflow, we achieved reliable month-resolved estimation of coppiced-stand age for Eucalyptus spp. plantations in Luzhai County, Guangxi, China. The workflow achieved 83.2% overall accuracy and a

Trade‑offs and timing of leaf defenses during development in two co‑occurring oaks with contrasting leaf habits
Research paper Key message Evergreen and deciduous oaks resolve the early ontogenetic “vulnerability window” with contrasting defense schedules: evergreens front‑load chemical deterrence (condensed tannins) and complete mechanical reinforcement later, whereas the deciduous prioritize rapid growth and earlier

A lightweight LiDAR-SLAM system integrated with semantic segmentation for the acquisition of forest biomass parameters
Research paper Key message We propose a lightweight LiDAR-based simultaneous localization and mapping system that integrates semantic segmentation. The system was evaluated on forest point clouds collected in real-world forest environments and on multiple publicly available datasets.

Aboveground biomass in seven tropical forest patches of Western-Africa: comparison of manual inventory and terrestrial laser scanning
Research paper Key message Aboveground biomass (AGB) increased from forest edge to forest interior in small forest patches of Western-Africa. In plots of 0.25 ha, AGB did not correlate with tree species richness or wood density. AGB in

Drought conditions could exacerbate nitrogen and phosphorus imbalances in important European forest tree species
Research paper Key message A large European forest monitoring dataset reveals a pattern of reduced foliar nitrogen (N) and phosphorus (P) concentrations following drought conditions in spruce and pine, and, in the case of P, beech and

Chemical timber tracing: combining tree-genera information lowers reference data needs and makes harvest location identification more accurate
Research paper Key message Chemistry-based tracing techniques are increasingly used for combating illegal timber trade, but they are currently limited by the small and fragmented reference datasets available. We introduce a model that integrates data from multiple

Forest change across the European Union: spatial patterns, drivers, and governance insights from a pan-European expert survey
Research paper Key message Forests in Europe are changing unevenly. Recovery dominates parts of Northern and Central Europe, while disturbance, degradation, and loss intensify in Southern and Eastern regions, and urbanization-driven fragmentation is spreading widely. A pan-European

Characterization of grassland and shrubland patches on post-mining Mediterranean slopes and the adjacent forest: soil, vegetation, and topography data
Data paper Key message The described database provides environmental information about a case study of post-mining slopes in northern Spain. It characterizes soil physicochemical properties (including first mineral horizon thickness), plant community attributes (diversity indexes and cover

Modeling crown width and canopy cover in Quercus suber L. stands: from forest management equations to 3PG-compatible formulations
Research paper Key message This study provides new equations to estimate crown width and percent crown cover of cork oak (Quercus suber L.), helping forest managers understand forest structure and making informed decisions on understory management and thinning
