Effects of Ips typographus (L.) and sanitation logging disturbance on organic matter decomposition and carbon in the humus layer in boreal Picea abies (L.) H. Karst. stands

Research paper Key message  Sanitation logging, aimed at mitigating the spread of European spruce bark beetle (Ips typographus L.) outbreaks in boreal stands, was associated with increased decomposition and loss of carbon from the humus layer, measured 10 years

From between-stand to within-tree variation: wood and timber quality of Norway spruce (Picea abies H. Karst) analyzed at scale using laser scanning and industrial data

Research paper Key message  Using laser scanning and industrial data, we found that over 70% of wood quality variability occurred within Norway spruce (Picea abies H. Karst) trees. The most important wood quality predictors were stem size, crown

ENSO advances spring phenology of temperate deciduous shrubs more than trees in Southeastern Wisconsin, USA

Research paper Key message The 2024 ENSO event advanced the timing of spring phenological phases of native shrubs significantly more than non-native shrubs and native trees in a temperate deciduous woodland fragment in Wisconsin, USA. This suggests

Inoculation success of Inonotus obliquus (Ach. ex Pers.) Pilát in birch (Betula pendula Roth, B. pubescens Ehrh.) and alder (Alnus incana (L.) Moench, A. glutinosa (L.) Gaertn.) in Estonia

Research paper Key message This is the first study to investigate the success of inoculation of Alnus incana and A. glutinosa with Inonotus obliquus (Ach. ex Pers.) Pilát, providing new insights about the potential cultivation of this valuable fungus under field conditions. Results show that conks

Impact of extreme precipitation events on summer deep seepage below temperate forests in the Northeastern Germany lowlands

Research paper Key message Stands stocked with European beech (Fagus sylvatica L.), sessile oak (Quercus petraea (Matt.) Liebl.), and Scots pine (Pinus sylvestris L.) show distinct deep seepage patterns. An increasing importance of extreme summer precipitation contributing to deep seepage

Crown–branching trade-offs mediate growth and resilience to drought, frost, and masting under moderate thinning in European Beech (Fagus sylvatica L.)

Key message Thinning boosts radial growth in European beech (Fagus sylvatica L.), but more is not always better: moderate thinning offers the best vitality balance by keeping resilience comparable to heavily thinned trees, while reducing the sensitivity to

Integrated modelling approaches for estimating total organic carbon, total nitrogen, total phosphorus, and ash content in forest floor samples using ATR-FTIR spectroscopy

Key message ATR-FTIR spectroscopy combined with statistical modelling provides accurate predictions of forest floor properties: total organic carbon, total nitrogen, total phosphorus and ash. Performance decreases in carbonate-rich samples, particularly for organic carbon and the carbon to

Assessing the effectiveness of protected areas and prioritizing conservation in fragmented Quercus brantii Lindl. and Q. macranthera Fisch. & C.A.Mey. ex Hohen. habitats in Iran under different climate change scenarios

Key message  We evaluated the effectiveness of protected areas under climate change scenarios for two keystone Iranian oaks: Quercus brantii in Zagros semiarid forests and Q. macranthera in Hyrcanian temperate forests. Major habitat losses and upslope shifts are projected for both

Combining wood anatomy and chemical fingerprinting maximizes tropical timber identification success

Key message  A combination approach to wood identification methods yields superior results when identifying timber originating from the Central African tropics. This is demonstrated by the performance of DART-TOFMS as a fine-tuning step after the microscopic analysis

Compatible models to predict tree crown ratio, crown length and height to the base of the crown for maritime pine (Pinus pinaster Aiton.)

Key message  This paper provides individual tree models to estimate crown variables in maritime pine (Pinus pinaster Aiton.). The estimation of crown variables, especially height to the base of the crown and crown length, is essential for forest
