Adaptation of Abies fargesii var. faxoniana (Rehder et E.H. Wilson) Tang S Liu seedlings to high altitude in a subalpine forest in southwestern China with special reference to phloem and xylem traits
Key message Abies fargesii var. faxoniana (Rehder et E.H. Wilson) Tang S Liu seedlings at high elevations compensate for the low efficiency of their water conducting system and high phloem hydraulic resistance by the enhancement in xylem:leaf

Improving the Fagacées growth model with an expanded common beech (Fagus sylvatica L.) data series from France and Germany
Key message The Fagacées growth model was originally designed for application in the Northern half of France. It is a robust model with potential applicability to a larger area, though this potential has not yet been verified.

Modelling the growth response to climate change and management of Tectona grandis L. f. using the 3-PGmix model
Key message Teak (Tectona grandis L. f.) is a native tree species of India. It is one of the most desirable timber species because of its strength, fine texture, and durability. Its growth is strongly dependent on

Survival and growth of Acacia senegal (L.) Wild. (Senegalia senegal (L.) Britton) provenances depend on the rainfall at the site of origin
By Véronique Lesage On 17 September 2021 In All published articles, Data in repository, Research paper
Key message Variation among provenances of Acacia senegal (Senegalia senegal (L.) Britton) in their survival and growth in height and diameter at two sites in Senegal could be partly explained by the climate at their site of

Mechanical properties of secondary quality beech (Fagus sylvatica L.) and oak (Quercus petraea (Matt.) Liebl.) obtained from thinning, and their relationship to structural parameters
Key message This paper investigates the juvenility limit and structure–property relationship in secondary quality beech (Fagus sylvatica L.) and oak (Quercus petraea (Matt.) Liebl.). The juvenile wood occupies a very small area near the pith. The stabilization

Effect of tree harvest, silvopastoral practices, and microclimate conditions on forest floor CO2 efflux in a sessile oak (Quercus petraea agg. [Matt.] Liebl.) forest
Key message Forest floor CO 2 efflux ( R f ; consisted of soil and potential vegetation) increased after forest harvest, but this response was changed by actual weather (especially drought and rains). Abstract Context Soil respiration

Estimation of breast height diameter and trunk curvature with linear and single-photon LiDARs
Key message New technologies can take us towards real precision forestry: the terrestrial single-photon avalanche diode (SPAD) light detection and ranging (LiDAR) has a great potential to outperform conventional linear mode LiDARs in measuring tree parameters at

A new approach for predicting board MOE from increment cores
By Véronique Lesage On 16 September 2021 In All published articles, Data in repository, Research paper
Key message Increment cores can provide improved predictive capabilities of the modulus of elasticity (MOE) of sawn boards. Multiple increment cores collected at different heights in a tree provide marginally increased accuracy over a single breast-height core,

Predicting crown width and length using nonlinear mixed-effects models: a test of competition measures using Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.)
Key message Including individual-tree competition indices as predictor variables could significantly improve the performance of crown width and length models for Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.). Moreover, distance-dependent competition indices are superior to distance-independent ones when

Single-tree crown shape and crown volume models for Pinus nigra J. F. Arnold in central Italy
Key message The crown volume of Pinus nigra trees can be modelled as a function of the total crown length and the crown radius at crown base to support forest management practices. Abstract Context The crown volume
