A decade-long study on mortality in European larch (Larix decidua Mill.), Japanese larch (Larix kaempferi (Lamb.) Car.) and their hybrid
By Carla Allais On 4 December 2025 In All published articles, Non classé, Open Access, Research paper
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
By Carla Allais On 4 December 2025 In All published articles, Non classé, Open Access, Research paper, Special issue/Topical collection
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

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
By Carla Allais On 2 December 2025 In All published articles, Non classé, Open Access, Research paper
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%

Tree growth in West African cocoa agroforestry systems: high timber yields and superior performance of natural regeneration
By Carla Allais On 2 December 2025 In All published articles, Non classé, Open Access, Research paper
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
