“…The global development of artificial forests is optimistic, comprising approximately 7% of the world's forest area yet supplying more than 50% of the world's raw timber production (Martínez-Cortés et al 2022). According to a report from the Food and Agriculture Organization of the United Nations, between 2010 and 2020, the annual increase in global artificial forests exceeded 3 million hectares.…”

Due to the continuous depletion of timber resources and the increasing ecological awareness among people, large-scale fast-growing artificial forests have become a key solution to address the imbalance between timber supply and demand. In recent years, the problem of low density and mechanical strength of fast-growing timber has been addressed through timber densification. However, densified timber still faces issues such as high moisture absorption and poor dimensional stability. Urea molecules can expand the volume of the non-crystalline region of cellulose to protect the cell wall structure of timber from damage during the densification process. In this paper, an effective modification strategy was proposed to prepare lightweight high-strength wood through the synergistic effect of urea vacuum impregnation treatment and high temperature densification, which solved the problem of poor dimensional stability of densified wood. Research results indicate that when the concentration of urea solution is at 50%, the maximum weight gain of the timber samples reaches 17.76%. After densification treatment, the absolute dry density of the test samples increased by more than 0.031g/cm3. Timber treated with a 50% urea solution and processed at 170°C demonstrates good dimensional stability, with a radial swelling rate of only 0.79% under a relative humidity of 65%. Therefore, the joint modification of wood using urea and high-temperature treatment is an effective and environmentally friendly method, presenting broad prospects for development.

Global climate crisis and severe water scarcity worldwide demand alternative genotypes that allow an adequate balance between production and water use while ensuring benefits for foresters. The genetic improvement of water use efficiency (WUE) in forest plantations could reduce water use without compromising yield. Above-ground biomass (AGB), saw-wood volume up to small-end diameter of 15 cm (V15), wood density (WD) and intrinsic WUE (WUEi) from wood carbon isotopic discrimination was evaluated in forty open-pollinated families of G. arborea grown in a tropical dry forest known as a water-limited environment, to select superior genotypes considering a balance in wood production and water use. Heritability of open-pollinated family means were moderate with values of h2f = 0.554 for AGB, h2f = 0.541 for V15, h2f = 0.608 for WD and h2f = 0.495 for WUEi. Significant genetic correlations between both WD and WUEi and production traits (p < 0.05) and a nonsignificant genetic correlation between WD and WUEi were found. Although production traits and WUEi showed moderate narrow-sense and family means heritabilities, considerable responses to selection of up to 13.7% in AGB, 15.5% in V15, 2.5% in WD and 3.0% in WUEi could be achieved from intensive selection of superior families. Our results showed that it may be possible balancing wood production and WUE by selecting open-pollinated families of G. arborea with higher V15 and WUEi. The deployment of these superior families can be used as a forest management strategy to adapt the species to future drought scenarios associated with global climate change.

Growth and yield of Retrophyllum rospigliosii pure plantations in the Colombian Andes

Most reforestation in Colombia, especially in the Andean region, are monocultures of pines and eucalyptus with defined nursery and silvicultural packages. Planting native species would avoid the widespread controversy over reforestation with exotic species. Nevertheless, there are few studies that evaluate the growth and yield of native species and provide supported data to establish new projects. Here, we modeled the growth and yield of the native coniferous Retrophyllum rospigliosii in different areas of the Colombian Andes in terms of mean diameter (D), height (H), and volume (V) as a function of age, based on longitudinal data from 115 research sample plots from three sites that were remeasured between 4 and 9 times for 20 years. We fitted the von Bertalanffy growth model for D, H, and V through Bayesian generalized nonlinear mixed models to model tree growth. The adjustment of the models for the absolute growth of R. rospigliosii was 0.99, 0.99, and 0.97 for D, H, and V, respectively. All models fulfilled all regression assumptions. Although the growth rates of R. rospigliosii differed between planted sites, R. rospigliosii plantations generally exhibited low growth and barely reached the sizes required for commercialization. These results suggest that the extensive use of R. rospigliosii in pure plantations is unlikely and discourages the massive propagation of R. rospigliosii.
