Growth models for two commercial tree species in upland forests of the Southern Brazilian Amazon

Wood Colorimetry for the Characterization of Amazonian Tree Species: A Subsidy for a More Efficient Classification

“…Nogueira et al (2005) evaluated the basic density of 186 Amazonian tree species and found that 73% of the species were classified as moderate-weight wood and only 23% as heavy woods. These results demonstrate that, in the Amazon region, there is a predominance of tree species with medium wood density, which is relevant for growth studies and for the definition of cutting cycles adopted in sustainable forest management (ANDRADE et al, 2019) and for the replacement of overexploited species with others with similar wood properties and sufficient growth stock (REIS et al, 2019).…”

“…The lowest and the highest values of basic densities were found for marupá (Simarouba amara) and jatobá (Hymenaea courbaril), with values of 0.337 g.cm -3 and 0.848 g.cm -3 , respectively. Recently, Andrade et al (2019) demonstrated that wood density is closely related to tree age and growth, with low-density Amazonian species (<0.600 g cm -3 ) showing rapid growth and high-density tree species characterized by slow growth. The wood of H. courbaril has a high density range of 0.76-0.96 g cm − 3 (ANDRADE et al, 2019) and is widely distributed in Brazil, occurring in dryland forests in the Amazon (LOCOSSELLI et al, 2017) and heavily marketed because of the high values and low variability of mechanical properties that enable structural use (LAHR et al, 2016).…”

“…The Amazon region is considered one of the largest reserves of tropical wood in the world, due to its extent, variability and due to the economic and ecological importance of its species. Among the Amazonian natural resources, in the context of sustainable forest management, wood is the one that has the highest economic profitability (ANDRADE et al, 2019;FORTINI, 2019).…”

From plots to policy: How to ensure long‐term forest plot data supports environmental management in intact tropical forest landscapes

“…For example, in Mexico, yields tropical forests under the Plan Piloto Forestal de Quitana Roo depend on the size distribution and growth rates of species that are extracted (Torres‐Rojo, Moreno‐Sánchez, & Mendoza‐Briseño, 2016). However, despite the many ecological and modeling studies, growth and yield models that incorporate how tree growth and mortality rates vary with environmental conditions and among species are often not used as the basis of timber management policy (Andrade et al., 2019; Hubbell & Foster, 1992). For example, in both Brazil and Peru, the only taxa‐specific information within the policy framework for timber extraction concerns the definition of minimum harvesting sizes (Andrade et al., 2019; Rondon et al., 2009) which is an approach that excludes much basic ecological information about different timber species.…”
