“…The results for basic density were consistent with those described in the literature for Savannah species, which range from 200 to 845 kg m -3 (Vale et al, 2002;Silva et al, 2015;Siqueira et al, 2020), and similar to those presented for E. gummiferum (620 kg m -3 ), Eriotheca gracilipes (360 kg m -3 ), P. reticulata (750 kg m -3 ) and A. fraxinifolium (610 kg m -3 ) (Vale et al, 2002;Testoni et al, 2009;Oliveira, 2014). Besides, WDB values close to 659 kg m -3 were reported for different species from the Cerrado of Minas Gerais (Oliveira et al, 2021), the same region as the trees collected in this study.…”

“…Among the main characteristics that express this quality is density, which is directly related to the volume of empty spaces in the wood. In addition to being a relatively easy-to-determine property, density is related to important environmental, technological, and economic aspects and to climate variables such as precipitation and temperature (Oliveira et al, 2021). It is also associated with other wood characteristics, such as contraction, swelling, and mechanical resistance of pieces (Schulgasser & Witztum, 2015;Amer et al, 2021;Gonya et al, 2021).…”

The objective of this study was to qualify the wood of the species Astronium fraxinifolium, Enterolobium gummiferum, Eriotheca pentaphylla, and Plathymenia reticulata of the Brazilian Cerrado for forestry productive purposes based on the classification of their wood basic density and fiber quality indices. Discs were removed at a height of 1.3 m from the ground, and opposing wedges were obtained. The analyzed parameters were: wood basic density, fiber dimension, and fiber quality indices. The wood basic density was negatively correlated with fiber length and thickness. E. pentaphylla presented low basic density, long fiber length, and greater fiber wall thickness. On the other hand, A. fraxinifolium, E. gummiferum, and P. reticulata woods presented medium/high basic density, short fiber length, and quality indices that foster them for energy purposes, paper production, and use in floors and civil construction.

“…They were classified as thin to thick walls, according to the classification of the IAWA Committee (Wheeler et al 1989). The thickness of the fiber wall, the frequency and diameter of the vessels, the amount of parenchymal tissue, in addition to other factors, e.g., environmental variables, can affect the density of the wood, and consequently its energy properties (Kollmann and Côté Jr. 1968;Panshin and De Zeeuw 1980;Zobel and Buijtenen 1989;Oliveira et al 2021). Thus, these anatomical characteristics make S. paniculatum wood present a medium density, i.e., approximately 700 kg•cm -3 (Machado Neto et al 2015).…”

Considering the extraordinary diversity of the Brazilian Cerrado and the difficulties related to the inspection of environmental crimes, knowing the wood and charcoal anatomy of widely exploited species is important. Thus, this study aimed to verify the anatomical characteristics of the wood and charcoal of Sclerolobium paniculatum. Therefore, anatomical characterizations of the wood and the charcoal produced were performed in order to compare the characteristics of both materials and observe any possible changes in the anatomical properties after carbonization. The results exposed that the qualitative anatomical characteristics of S. paniculatum wood can be maintained after the carbonization process. However, quantitatively, the carbonization increased the vessel frequency value and height and width of rays, despite reducing the frequency of rays. The diameter of the vessels was not altered by carbonization. This characterization of the species can then serve as a database for future identification of charcoal produced with this wood. In addition, it can encourage increasing the quality of inspection and consequently reducing the illegal exploitation of the species in natural environments.

“…We further compare our spatial patterns of wood density maps with other independent regional wood density products (Chave et al, 2009;Oliveira et al, 2021). Chave et al (2009) used the 16,468 wood density entries from Dryad data repository, which have not been used in our analysis due to the unavailability of geographic coordinate information, to generate a wood density map for North and South America (hereafter JC09).…”

“…Up to now, despite several forest inventory data have been used for shaping regional wood density distribution, as demonstrated by Chave et al (2009), Poyatos et al (2018), andOliveira et al (2021), a reliable global-scale spatially explicit product of tree wood density is lacking. Here, we conducted a comprehensive collection of tree-level wood density measurements spanning all global climate biomes.…”

Wood density is a fundamental property related to tree biomechanics and hydraulic function while playing a crucial role in assessing vegetation carbon stocks by linking volumetric retrieval and a mass estimate. This study provides a high‐resolution map of the global distribution of tree wood density at the 0.01° (~1 km) spatial resolution, derived from four decision trees machine learning models using a global database of 28,822 tree‐level wood density measurements. An ensemble of four top‐performing models combined with eight cross‐validation strategies shows great consistency, providing wood density patterns with pronounced spatial heterogeneity. The global pattern shows lower wood density values in northern and northwestern Europe, Canadian forest regions and slightly higher values in Siberia forests, western United States, and southern China. In contrast, tropical regions, especially wet tropical areas, exhibit high wood density. Climatic predictors explain 49%–63% of spatial variations, followed by vegetation characteristics (25%–31%) and edaphic properties (11%–16%). Notably, leaf type (evergreen vs. deciduous) and leaf habit type (broadleaved vs. needleleaved) are the most dominant individual features among all selected predictive covariates. Wood density tends to be higher for angiosperm broadleaf trees compared to gymnosperm needleleaf trees, particularly for evergreen species. The distributions of wood density categorized by leaf types and leaf habit types have good agreement with the features observed in wood density measurements. This global map quantifying wood density distribution can help improve accurate predictions of forest carbon stocks, providing deeper insights into ecosystem functioning and carbon cycling such as forest vulnerability to hydraulic and thermal stresses in the context of future climate change.
