Survival and growth of Acacia senegal (L.) Wild. (Senegalia senegal (L.) Britton) provenances depend on the rainfall at the site of origin

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

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

Modeling the forest dynamics of the Sierra Nevada under climate change using SORTIE-ND

Key message Model simulation results suggest that forests in the Sierra Nevada mountains of California will tend to increase in density and basal area in the absence of fire over the next century, and that climate change

Reduction of growth stresses in logs of Hieronyma alchorneoides Allemão from fast-growth plantations using steaming and heating: effects on the quality of lumber

Key message Growth stresses are usually present in the fast-growing trees of forest plantations and can be evaluated along stem diameter. Growth stresses are relaxed after tree felling and during sawing and drying, and are manifested in

Early effects of two planting densities on growth dynamics and water-use efficiency in Robinia pseudoacacia (L.) and Populus deltoides (Bartr. ex Marsh.) × P. nigra (L.) short rotation plantations

Key message Black locust is an interesting option for biomass production at sites prone to water shortage because the species combines water-use efficiency and a biomass yield largely superior to that of poplars under the conditions of
