Height-diameter models are fundamental for the inventory of timber, biomass and carbon. Located in the central region of Mexico, Abies religiosa is a conifer with high timber value that lacks models to estimate its height as a function of diameter . The objective of this study was to determine a local height-diameter model for A. religiosa trees under a mixed-effects model approach in the region of Tlaxco, Tlaxcala, Mexico. The first step consisted in evaluating the quality of fit of three growth models and one power model. We used height-diameter data of 1,539 trees measured in 197 circular plots of 1,000 m 2 . The selected model was the Weibull, which was adjusted in a second step under the mixed-effects modelling approach. Our results showed that the most accurate predictive capacity was obtained when using the sub-basin covariate as a clustering factor and the random effect in the parameter corresponding to the asymptote. Under this approach, the goodness of fit of the model was superior to the traditional one adjusted by nonlinear least square. Comparatively the gains in fit statistics R 2 , RSME and AIC were of 12.19 %, 47.99 % and 8.46 %, respectively. The proposed model is robust, reliable, and biologically coherent for its operational application in the forest management of A. religiosa in the study region.

Prosopis caldenia is a woody perennial species endemic to the temperate semi-arid phytogeographic region of central Argentina known as the Caldén district. Currently, some areas of this region are degraded because of livestock, fires, the advance of the agricultural frontier, and lack of forest management, among others. To improve the restoration of this important species within its natural distribution area and/or for the expansion of the wooded area, propagation methods must be developed that produce acceptable numbers of seedlings when seeds are put in conditions to germinate. The seeds of P. caldenia present an impermeable coat that prevents uniform imbibition. The literature is scarce regarding the study of scarification methods in this species. The objective of this work was to evaluate which pre-germination method (mechanical, chemical, or thermal) best adapts and improves the germination parameters. The seeds were placed in a germination chamber at a temperature of 30 oC for 12 days and daily observations of germination, non-embedded seeds, non-germinated embedded seeds, root length, and germination indices were carried out. The results indicate that mechanical scarifying achieves the highest germination rate, germination indices, and root length (P < 0.05) followed by acid treatment. This research should be repeated in the nursery to verify whether the laboratory results are maintained under plant production conditions.

The sawing of Hymenaea courbaril is complex due to its high density and abrasiveness. These factors accelerate the wear on saw blade teeth, and as a consequence, increase the cutting variability and process costs. The effect of cutting parameters on standard deviation of sawn-wood thickness was evaluated to propose optimal sawing conditions. A log carriage bandsaw with two saw blade geometries, three log diameter classes, and two feed rates were used to carry out the sawing tests. The results showed that the sawing variation expressed by the total standard deviation of board thickness was lower than 1 mm, when log diameter was lower than 0.79 m, and the log carriage feed rate was lower than or equal to 10 m min -1 for both saw geometries. The sawing thickness was affected by log diameter and log carriage feed rate, while saw geometry was not statistically significant. However, the goal of this initiative was not an estimation of the changes on sawmill productivity. Before this study, all log classes were processed with a log carriage feed rate of no higher than 10 m min -1 . Consequently, given the estimated total standard deviations, it can be suggested that the logs of class 2 could be sawn at a 50 % higher rate without altering the cutting precision, improving sawmill productivity.

The box tree moth poses a threat to the Anatolian boxwood ( Buxus sempervirens ) which has significant economic and ecological value in Türkiye. This study aimed to determine the economic feasibility of pest control with solar-powered light-pheromone (SPLP) traps against the box tree moth in the Ağva Forest District of Şile Forest Enterprise, which is the only region in Türkiye with a management plan for boxwood shoot utilization. For the economic feasibility analysis, approaches including net present value, benefit-cost ratio, and the comparison of discounted finite cost of control with the capital value of infinite revenues were used. Considering the revenues of the Şile Forest Enterprise from the sale of the boxwood shoots in a finite period, it was found that pest control with the SPLP traps is not economical, producing a benefit-cost ratio of 0.371 with a net present value of -229,647.10 TL. In addition to the revenue of the enterprise, after taking into account regional income losses, water production value, and the benefits of other non-market ecosystem services provided by boxwood areas, the benefit-cost ratio increased to 2.688, and pest control became economically feasible. It was determined that the capital value of the infinite annual revenues from boxwood shoots was greater than the present value of the pest control costs against the box tree moth in a period.

Acacia melanoxylon is an exotic and invasive species in Chile, one that is difficult to control by cutting trees and applying chemical products. This has made its management for ecological restoration difficult, signifying the need to investigate alternative, effective and environmentally friendly methods. The objective of this study was to evaluate the degree of in vitro biodeterioration of A. melanoxylon wood with Trametes versicolor and Schizophyllum commune fungus, collected from naturally parasitized stumps in the field. Kinetic growth studies and biodeterioration tests on A. melanoxylon wood were carried out over four months in the laboratory. Trametes versicolor had the highest colony development at eight days on 2 % malt agar and the highest significance of biodeterioration with 25.3 % in average loss of wood mass, with abundant colonization and aggressiveness, compared to 6.1 % biodeterioration by S. commune. However, the pathogenicity of S. commune in stumps in the field must be evaluated before this fungus can be ruled out as a biocontrol. These results correspond to the first studies regarding the in vitro evaluation of the biodegradation capacity of xylophagous fungi in the search for potential biocontrols for A. melanoxylon that contribute to the success of ecological restoration in forests.
