A decade-long study on mortality in European larch (Larix decidua Mill.), Japanese larch (Larix kaempferi (Lamb.) Car.) and their hybrid

Key Message This study, based on a clonal larch experiment under contrasting soil water conditions, showed that Japanese larch exhibited the highest drought-induced mortality, followed by the hybrid and European larch. Mortality was driven by low soil

Forest attribute maps: a support for small area estimation of forest disturbances

Key Message Forest attribute maps generated using national forest inventory and remote sensing data can be used to quantify forest attributes (i.e., growing stock volume, basal area) affected by disturbance events (like bark-beetle induced damage) through small

The use and integration of airborne laser scanning and satellite time series data in precision forest management for plantations of fast-growing tree species

Key message  Integrating airborne laser scanning and satellite time series data across the forest rotation enhances decision-making in precision forestry. This review supports forest managers by illustrating practical applications of these remote sensing technologies at different stages

Adapting forests to climate change: an experiment to promote different tree species in mixed Scots pine forests (Pinus sylvestris L.)

Key message  We have applied various silvicultural treatments to enhance the adaptation of Scots pine (Pinus sylvestris L.) mixed forests to climate change in Montesquiu Castle Park (Catalonia, NE Spain). Some treatments have shown positive effects, such as increased

Extraction of individual tree attributes using ultra-high-density point clouds acquired by low-cost UAV-LiDAR in Eucalyptus plantations

Key message  In this paper, we first introduced a novel method for directly measuring tree diameters from UAV-LiDAR point clouds utilizing the χ2-filtering technique and a technique for measuring tree heights using pseudo-waveforms. Keywords  Individual tree detection; Tree

How much timber from Norway spruce (Picea abies L.) is left on the harvesting site as treetops? A study on scaling and grading yields of harvesters

Key message  Timber losses during Norway spruce (Picea abies L.) harvesting with the cut-to-length method were analyzed using data from 41,948 stems. The volume of timber left on the site after CTL harvesting reached 0.111% overall and 0.454%

Transnational Forest Governance Arrangements dataset (TFGA-dataset)

Key message  The Transnational Forest Governance Arrangements dataset is the first to compile a comprehensive set of governance arrangements whose spatial ambits span three or more national jurisdictions, and which formally address forests as a main issue. As

Tree growth in West African cocoa agroforestry systems: high timber yields and superior performance of natural regeneration

Key message Cocoa agroforestry systems (AFS) in West Africa represent an underexplored yet promising source of timber. Within these systems, species can reach a 50-cm diameter as early as 14 years of age. Naturally regenerated trees grow

First report: Xylosandrus compactus (Eichhoff, 1876), new invasive ambrosia beetle in Montenegro

Key message  The ambrosia beetle Xylosandrus compactus (Eichhoff, 1876), originally from Southeast Asia, was first found in Europe in 2010, specifically in Italy. Since then, X. compactus has rapidly spread across southern Europe, including France, Spain, Greece, Turkey, Malta, Slovenia, Russia,
