“…The correlation between copaíba growth and precipitation at PES indicates that, in this case, the increase of rainfalls in the summer and during the transition of seasons favor the growth rate of this species. A number of authors confirm this analysis, concluding that precipitation is the main factor that influences the growth of trees (FRITTS, 1976;WORBES et al, 2003;DÜNISCH et al, 2003;BRIENEN;ZUIDEMA, 2005;GEBREKIRSTOS et al, 2008;SASS-KLAASSEN et al, 2008;MELO JÚNIOR et al, 2011;LATORRACA et al, 2015;MATTOS et al, 2015). Additionally, a significant correlation was detected between the growth of the rings and the precipitation in the transition from the dry season to the wet season in the current and in the previous year.…”

“…Dendrochronology is a science that studies the formation of growth rings in plant species. The formation of these rings can be influenced by climatic, physical, genetic and/or anthropic events, such as precipitation, temperature, frequency of floodings, prolonged drought, soil quality, species deciduousness, and types of forest management (WORBES et al, 2003;LISI, et al, 2008;SOUTHWORT et al, 2013;LATORRACA et al, 2015;MATTOS et al, 2015;LATORRACA, 2016;FIGUEIREDO FILHO et al, 2017). Thus, growth rings can provide information on past and present environmental conditions (SOUTHWORT et al, 2013;FIGUEIREDO FILHO et al, 2017).…”

This study aims to build a chronology of the growth rings of Copaifera langsdorffii (copaíba) in order to understand the dynamics of vegetation types that occur on a river island in the Cerrado biome. For this purpose, we selected 30 trees of copaíba established in a vegetation of Mata Seca Sempre-Verde in the Pirapitinga Ecological Station (EEP), state of Minas Gerais, Brazil. Two radial samples from each tree were collected by an auger. The samples were treated by mechanical polishing for better visualization of the growth rings, and consequently further delineation and measurement. Later, the width of the growth rings was verified in order to generate a master time series of the specie. To check the influence of meteorological factors, we used the Pearson correlation (p < 0.05). The results showed that the population of copaíba in the EEP presented dendrochronologyc potential, which was confirmed by the high values of wide growth rings correlation within and between trees. The dendrochronologyc analysis revealed that copaíba trees were already present before the dam filling, but with lower population density than today. It was also possible to infer that the development of the vegetation type Mata Seca Sempre-Verde occurred since the decade of the 1970. The average sensitivity was enough to consider the species sensitive to environmental variations. Precipitation and temperature only influenced positively the growth rings in the transition from dry to wet seasons. The results revealed information about the dynamics of the local vegetation, elucidating the changes that occurred in the environment in which the population of copaíba is established.

“…Growth series obtained by dendrochronology became more popular as an alternative to permanent-plot data to supply the demand for information and growth models of species (Brienen, 2005;Brienen;Zuidema, 2006a;Schöngart, 2011;Mattos et al, 2015;Canetti et al, 2017;Groenendijk et al, 2017;Miranda, D. L. C. et al, 2018). Growth ring analysis is a fast and reliable tool for assessing tree age, determining its growth rates over the life cycle, and identifying growth differences between species (Groenendijk et al, 2017;Rosa et al, 2017).…”

BackgroundThis study aimed to develop a procedure to determine which logging diameter would achieve optimal wood production by species, aiming to support sustainable management of the Amazon forest. Two main methodologies of analysis by species were combined: probability density function (PDF) and growth modeling. The growth models were used to derive the volume increment curves at the individual tree level. To detect the points of maximum annual increment in volume at the population tree level we used PDF with adjusted growth equations.ResultsThe population maximum annual volumetric increments occurred in smaller diameters compared to that of the individual-level. When combining shorter cutting cycles with the population biological rotation point considered as the minimum cutting diameter (MCD), we observed higher annual increments in volume than that achieved using the Brazilian law criteria (MCD = 50 cm) or other MCD tested.ConclusionThe procedure proposed may be used by forest managers and forest law-makers, aiming to maximize sustainable wood production in the Amazon forest.

“…It also allows the estimation of wood production and calculation of the harvesting time accurately (Skovsgaard and Vanclay, 2008;Braz et al, 2012). Moreover, this information also describes forest competition effects (Curto, 2015), which assists in establish better periods for silvicultural interventions (Santos et al, 2015), periods required for the restoration of the removed forest volume (Braz et al, 2014), forest relationships with the climate, and site index (Mattos et al, 2015), using simple models. These models assume that the forest production and dynamics is an effect of its age, site index and competition.…”

Information on the diameter at the breast height (DBH) growth of trees can be useful to understand their productivity and temporal dynamics in natural forests. This study presents the first results of increments in DBH of Araucaria angustifolia trees since their logging prohibition in southern Brazil, in late 1970s. We used dendrochronology techniques in 210 individuals in three different sites, which allowed a retrospective analysis of the DBH increment from 60 to 150 years. We adjusted temporal dimensional models whose results may help to support a sustainable forest management of A. angustifolia in southern Brazil. The results showed that the width of annual growth rings varied from 0.04 to 4.8 cm year-1 along the last 60 to 150 years, and the mean annual increment ranged from 0.3 to 0.9 cm year-1. The DBH increment accumulated in the last ten years showed a decreasing pattern, indicating that most of the sampled trees had already reached maturity. This result denotes a proportional loss in DBH increment with increasing DBH and age. Decreasing DBH growth rates became even more evident in the last ten years (i.e. ~0.15 cm year-1), indicating a need of silvicultural intervention in some sites to reduce competition among trees for soil nutrients and light. Regarding the average DBH increment growth, the time the trees need to reach the optimal DBH harvesting diameter of 40 cm ranged from 25 to 112 years, according to the local site index characteristics. The curve inflection point that represents the DBH increment occurred between 35 and 45 years for this specific DBH. These results confirm the viability and need of forest management practices of A. angustifolia trees due to the saturation of the trees DBH growth and increment capacity that reached its inflection. Therefore, since their logging prohibition, most A. angustifolia trees reached their optimal DBH harvesting size. Forest management is necessary for conservation of the forest structure. It would favor the growth of young A. angustifolia, seedling productions, the natural regeneration of this species and genetic diversity; and stimulate the increase of timber production.
