The flexural lumber properties of Pinus patula Schiede ex Schltdl. & Cham. improve with decreasing initial tree spacing

Key message An increase in the stiffness of lumber with a decrease in initial tree spacing was confirmed for Pinus patula Schiede ex Schltdl. & Cham. The underlying properties of microfibril angle, wood density and knot frequency

CO2 fertilization, transpiration deficit and vegetation period drive the response of mixed broadleaved forests to a changing climate in Wallonia

Key message The change in forest productivity was simulated in six stands in Wallonia (Belgium) following different climate scenarios using a process-based and spatially explicit tree growth model. Simulations revealed a strong and positive impact of the

Functional distance is driven more strongly by environmental factors than by genetic relatedness in Juniperus thurifera L. expanding forest stands

Key message In our study of colonisation of abandoned farmland by Juniperus thurifera L., environmental and geographic distances were stronger drivers of functional differentiation among trees than genetic distance and tree intrinsic features. However, these effects varied

Climate warming differently affects Larix decidua ring formation at each end of a French Alps elevational gradient

Key message The ongoing global warming tends to reduce Larix decidua radial growth and ring wood density at the bottom of an elevational gradient in the French Alps, while it has a less marked effect at the

Predicting individual tree growth using stand-level simulation, diameter distribution, and Bayesian calibration

Key message We propose a methodology to develop a preliminary version of a growth model when tree-level growth data are unavailable. This modelling approach predicts individual tree growth using only one-time observations from temporary plots. A virtual

Which matters more for wood traits in Pinus halepensis Mill., provenance or climate?

Key message Intra-annual wood density fluctuations are valuable indicators of the role of the local climate and provenance origins on tree growth. These intra-ring wood features were the most informative about local adaptation and phenotypic plasticity of

Using forest gap models and experimental data to explore long-term effects of tree diversity on the productivity of mixed planted forests

Key message In this exploratory study, we show how combining the strength of tree diversity experiment with the long-term perspective offered by forest gap models allows testing the mixture yielding behavior across a full rotation period. Our

How do social status and tree architecture influence radial growth, wood density and drought response in spontaneously established oak forests?

Key message During the past decades, a multitude of oak stands have spontaneously established across the pine-dominated landscapes of the French Landes de Gascogne. Yet their future performance under modern climate change is unknown. We show that

Performances of different methods of estimating the diameter distribution based on simple stand structure variables in monospecific regular temperate European forests

Key message Using the three characteristic points of a forest stand, dg (mean quadratic diameter), dmin(diameter of the smallest tree) and dmax (diameter of the largest tree), appears informative enough to determine the parameters of the whole

National scale variability in forest stand variables among regions of provenances in Spain

Key message An in-depth characterization of the forests of 10 dominant species by stand variables at national scale showed, that overall, stands growing in the southernmost regions of Spain display low regeneration. Otherwise, the relationships between stand
